Template:WikiProject Bridges redirect

Would anyone mind if I changed the redirect for {{WikiProject Bridges}} to point to {{WikiProject Bridges article}} instead of {{WikiProject Bridges Member}}? Alot of article talk pages use the member template incorrectly, when the article template should have been used. There are only 5 or 6 pages that use the redirect for its current purpose and roughly a hundred that don't. I'd also fix the relatively pages that use the redirect for the member template. --​​​​D.B.talk•contribs 04:16, 2 February 2009 (UTC)

Live load capacities

I have been informed that BP Pedestrian Bridge was designed for a live load of 100psf. What does this mean and can you help me compare this to a standarad, policy, regulation, law, or something similar.--TonyTheTiger (t/c/bio/WP:CHICAGO/WP:LOTM) 17:33, 2 October 2008 (UTC)

Complicated topic. PSF would be pounds-per-squarefoot, I expect, but I'm likely wrong. For Ohio loading standards, see [1], as an example of what's complicated about this and how they answered it in Ohio. An example of its use is at Smolen-Gulf Bridge, a new covered bridge supposed to be opened yesterday. Hm, I wonder if that happened? - Denimadept (talk) 20:39, 2 October 2008 (UTC)
I have been given further information that the 100 psf live load is a general loading requirement for the City of Chicago for areas where the public can assemble. I need to find city code I guess. Any advice would be helpful.--TonyTheTiger (t/c/bio/WP:CHICAGO/WP:LOTM) 17:28, 3 October 2008 (UTC)
Does Chicago have a city engineer or department of transportation office? - Denimadept (talk) 17:50, 3 October 2008 (UTC)
The requirement you are looking for would be contained in the structural code that was used to design the bridge. 100 pounds per square foot of live load is about right for anywhere you would expect people to gather at maximum density (shoulder to shoulder). For a reference, you can look here, where the author can be quoted to say that "for corridors and lobbies, the code requires a live load of 100 psf." If you had a set of the structural plans, they would state which code the structural engineer used. He could have used either the current building code adopted by the city of Chcago (likely the Internation Building Code (IBC)) or the AASHTO Guide Specifications for Design of Pedestrian Bridges. The city's code is constantly updated, se even if you find their current version on-line (which I easliy did), you will not know what code was in effect at the time the plans were approved by the city (and transportation dept since it crossed their road). Either way, this is probably more detail than needed for a Wikipedia article. - ¢Spender1983 (talk) 03:04, 4 October 2008 (UTC)
I would strongly discourage anyone from citing live load capacities in a Wikipedia article. A structure may have been designed for a certain live load, but that design may no longer be valid in light of subsequent advancements in structural analysis methods and understanding of material capacities, not to mention that some structures (especially bridges) lose capacity through deterioration over time. Rating structures for live load capacity carries a legal responsibility and is best left up to licensed civil and structural engineers.Martindelaware (talk) 21:29, 27 March 2009 (UTC)

Coordinators' working group

Hi! I'd like to draw your attention to the new WikiProject coordinators' working group, an effort to bring both official and unofficial WikiProject coordinators together so that the projects can more easily develop consensus and collaborate. This group has been created after discussion regarding possible changes to the A-Class review system, and that may be one of the first things discussed by interested coordinators.

All designated project coordinators are invited to join this working group. If your project hasn't formally designated any editors as coordinators, but you are someone who regularly deals with coordination tasks in the project, please feel free to join as well. — Delievered by §hepBot (Disable) on behalf of the WikiProject coordinators' working group at 04:59, 28 February 2009 (UTC)

"Himalayan" design?

What is this kind of bridge called?

The first photo is used in:

--Una Smith (talk) 18:25, 17 March 2009 (UTC)

I would classify the subject bridge as a simple suspension bridge because the deck follows the catenary (curve) of the suspension cables. I don't know what makes it Himilayan design. It could be the stabilizing system: the extra cable on each side with the inverted catenary and the connecting wires. - ¢Spender1983 (talk) 21:32, 22 March 2009 (UTC)

Here are some others. --Una Smith (talk) 18:37, 17 March 2009 (UTC)

The first is also a simple suspension bridge. The last two are of a suspended-deck suspension bridge (the type in the main suspension bridge article). This bridge also has that interesting stabilizing system. - ¢Spender1983 (talk) 21:32, 22 March 2009 (UTC)
Thanks. That's what I expected to hear. Any idea what this class of stabilizing system is called? --Una Smith (talk) 03:31, 23 March 2009 (UTC)
I would call it an inverted catenary. Shameless plug: there is a discussion of various stabilizing systems in a paper that I co-authored, Justin M. Spivey, Dario A. Gasparini, Stephen G. Buonopane, and Thomas E. Boothby, "Stiffening Suspension Bridges," in Proceedings of an International Conference on Historic Bridges (Morgantown: West Virginia U. Press, 1999): 105-115.Martindelaware (talk) 21:21, 27 March 2009 (UTC)
Perhaps you would e-mail me the PDF? --Una Smith (talk) 21:34, 27 March 2009 (UTC)

I sent you an e-mail; reply and I'll send you the PDF. Martindelaware (talk) 03:23, 18 April 2009 (UTC)

I posted the references on Talk:Suspension_bridge#Name_for_cables_underneath_the_span - ¢Spender1983 (talk) 02:42, 16 April 2009 (UTC)

Bridges by structural type

For Suspension, Arch, Cable-stayed and Moveable, I think they should be placed directly in their main category. That is what the project page currently says to do. I don't think that the total number of articles will overwhelm the category.
My gut feeling is that there are enough Truss bridges that putting all bridges of that type into one category would be too large. These should be broken into country/region/state.
Are girder bridges notable enough to be organized into categories by that type? - ¢Spender1983 (talk) 03:58, 4 May 2009 (UTC)

tunnels

Is there a WikiProject Tunnels to complement this? 70.29.213.241 (talk) 04:24, 13 April 2009 (UTC)

See Wikipedia:WikiProject Council/Proposals/Tunnels. __meco (talk) 01:09, 8 May 2009 (UTC)

road bridges category

If fully populated, the Category:Road bridges would contain 95% or so of the bridges in WP. Is this category a good idea? If so, it is partially divided into country, even US state subcats. Should it be fully divided into country/state subcats or have no subcats? Hmains (talk) 00:49, 2 May 2009 (UTC)

No it's not a good idea to populate Category:Road bridges. Category:Concrete bridges and Category:Girder bridges would also be too large if fully populated. Would these also get broken down by country/state or region? For a "typical" prestressed concrete girder bridge, would you place it in Category:Bridges in Montana, Category:Concrete bridges in Montana, Category:Girder bridges in Montana, and Category:Road bridges in Montana?
There is definitely some work to needed to establish a better taxonomy in categorizing bridges. I am willing to discuss and help. - ¢Spender1983 (talk) 03:58, 4 May 2009 (UTC)

By the way, here is a good reference to show that engineers have been categorizing bridges by the mode of traffic carried for many years. I think this is important to show that we are not "creating" catergorization which could be considered original research.

  • Waddell, J.A.L. (1916). Bridge Engineering - Volume 1. New York: John Wiley & Sons, Inc. p. 341.

So engineers have been doing this for more than one hundred years. I note that Waddell basically has categories for (1) Rail bridges, (2) Road-rail bridges (or "combined bridges" as he called them), (3) road bridges (or "highway" bridges as he calls them, which carry vehicles, pedestrians and "herded animal traffic"), and (4) pedestrian bridges. - ¢Spender1983 (talk) 03:58, 4 May 2009 (UTC)

  • I am confused. If a category exists Category:Road bridges, then it should be fully populated with every road bridge; otherwise, it should be deleted. I would not propose to have road bridges catgory broken down by anything and would also upmerge its current subcats. Hmains (talk) 02:55, 8 May 2009 (UTC)

GA Sweeps invitation

This message is being sent to WikiProjects with GAs under their scope. Since August 2007, WikiProject Good Articles has been participating in GA sweeps. The process helps to ensure that articles that have passed a nomination before that date meet the GA criteria. After nearly two years, the running total has just passed the 50% mark. In order to expediate the reviewing, several changes have been made to the process. A new worklist has been created, detailing which articles are left to review. Instead of reviewing by topic, editors can consider picking and choosing whichever articles they are interested in.

We are always looking for new members to assist with reviewing the remaining articles, and since this project has GAs under its scope, it would be beneficial if any of its members could review a few articles (perhaps your project's articles). Your project's members are likely to be more knowledgeable about your topic GAs then an outside reviewer. As a result, reviewing your project's articles would improve the quality of the review in ensuring that the article meets your project's concerns on sourcing, content, and guidelines. However, members can also review any other article in the worklist to ensure it meets the GA criteria.

If any members are interested, please visit the GA sweeps page for further details and instructions in initiating a review. If you'd like to join the process, please add your name to the running total page. In addition, for every member that reviews 100 articles from the worklist or has a significant impact on the process, s/he will get an award when they reach that threshold. With ~1,300 articles left to review, we would appreciate any editors that could contribute in helping to uphold the quality of GAs. If you have any questions about the process, reviewing, or need help with a particular article, please contact me or OhanaUnited and we'll be happy to help. --Happy editing!

Pamban Bridge

Hi

I heard that the Pamban Bridge in Rameswaram, India also opens up for the ships to pass through.

I read the same in Wikipedia. However i do not find it mentioned in the Vertical Lift Bridge page.

Does it not come under Vertical Lift Brige.

Chinese construction site

I tripped over this: 30°39′19″N 111°19′30″E / 30.655178°N 111.324867°E / 30.655178; 111.324867 Use Google Maps. It looks like China is building some kind of bridge with a possibly suspension mainspan toward the northeast end. It's kind of unclear to me just where this is going, as there's no road on the south west end that I can detect. Anyone know what's going on here? - Denimadept (talk) 20:47, 28 July 2009 (UTC)

Indeed, there is something under construction there, but I doubt it will be record-breaking. However, the topography of the terrain to the southwest is such that it is quite likely that a tunnel will be dug there. There is a big construction site on the other side of that mountain, where a straight line from the bridge would cross the road. -- Blanchardb -Me•MyEars•MyMouth- timed 03:40, 5 August 2009 (UTC)
Looks like a rail line; if you follow it to the northeast it appears to end at one. It's probably the Shanghai-Nanjing-Hefei-Wuhan-Chongqing-Chengdu high-speed line shown on [2] and listed on High-speed rail in China. --NE2 03:45, 5 August 2009 (UTC)

Stolma Bridge in List of longest cantilever bridges

I have just created an article on this bridge based on the existing articles in the Norwegian and German Wikipedias.

Also, spaghetti bridge carries a bit of fame for competitions. I don't see how one could merge into another. I'll cross link them in "See also" for now.

Highest bridge

Both dwarfing the Royal Gorge Bridge with a clearance of 321 m. Now the articles for the Millau Viaduct and Royal Gorge Bridge state that they are the highest ones, the Millau discrediting the Royal as only a pedestrian bridge and taking over as the real highest bridge.

Arsenal Bridge, a CSX Transportation bridge in Philadelphia

The Harrisburg Subdivision page mentions the Arsenal Bridge, a CSX Transportation rail bridge over the Schuylkill River and the Arsenal Interlocking.

Strucurae - external link versus reference

The template {{Structurae}} is perfectly adequate for external links. However, it does not give authorship or typical details required for sources. Does anyone agree with me that a template which produced the information below would be helpful? This template could be similar to the {{Structurae}} template in that the editor only add the structure number and other minimal details such as access date to produce a fully detailed reference like the one below.

Input would be something verey similar to the existing Structurae template: {{Structurae reference|id = s0000001| title = Akashi Kaikyo Bridge| accessdate =2010-08-14}}

Wouldn't this be an improvement to our bridge articles and give proper credit when Structurae is used as a reference? I am not experienced at templates, so I would like to see if anyone wants to try to code it before I try. - ¢Spender1983 (talk) 18:53, 14 August 2010 (UTC)

Because it is your image and you own the copyright, it is best if you upload the image. (You then get to pick what copyright you release it under.) This means that you will need to get your ten edits done. I am not sure, but I think that edits on the talk page (like this one) might count.

Bridge articles have been selected for the Wikipedia 0.8 release

Version 0.8 is a collection of Wikipedia articles selected by the Wikipedia 1.0 team for offline release on USB key, DVD and mobile phone. Articles were selected based on their assessed importance and quality, then article versions (revisionIDs) were chosen for trustworthiness (freedom from vandalism) using an adaptation of the WikiTrust algorithm.

We would like to ask you to review the Bridge articles and revisionIDs we have chosen. Selected articles are marked with a diamond symbol (♦) to the right of each article, and this symbol links to the selected version of each article. If you believe we have included or excluded articles inappropriately, please contact us at Wikipedia talk:Version 0.8 with the details. You may wish to look at your WikiProject's articles with cleanup tags and try to improve any that need work; if you do, please give us the new revisionID at Wikipedia talk:Version 0.8. We would like to complete this consultation period by midnight UTC on Sunday, November 14th.

We have greatly streamlined the process since the Version 0.7 release, so we aim to have the collection ready for distribution by the end of November, 2010. As a result, we are planning to distribute the collection much more widely, while continuing to work with groups such as One Laptop per Child and Wikipedia for Schools to extend the reach of Wikipedia worldwide. Please help us, with your WikiProject's feedback!

If you have already provided feedback, we deeply appreciate it. For the Wikipedia 1.0 editorial team, SelectionBot 16:31, 6 November 2010 (UTC)

Beam bridge

RfC: Yet another attempt at jumpstarting WikiProject Tunnels

History

We have three options:

  1. Do nothing—let tunnels linger like they have been doing until now.
  2. Create WikiProject Tunnels.
  3. Change the scope and name of the current project to include both bridges and tunnels equally.

Perhaps there are more options (if we consider WikiProject Civil Engineering and the creation of a work-group/taskforce within an existing project). As RfCs go this one will we automatically closed after 30 days (although it may be manually extended if need be). __meco (talk) 09:09, 16 November 2010 (UTC)

  • I'm no civil engineer, but it seems to me that things like Gilbert Heathcote's tunnel have nothing in common with bridges at all. Surely there are class of tunnels that are more like mines than like bridges? Such as Adit or Sough? And what about races for hydro-electric generators? --Robert EA Harvey (talk) 13:28, 21 November 2010 (UTC)

Bridge replacement

Taking the situation at Berkley-Dighton Bridge, I'd like to suggest a way to handle a bridge replacement. Using the situation at Tay Rail Bridge as a guide, I'd suggest that we keep the structure number in mind. At the B-D Bridge, the third bridge is now gone. That does not mean it never existed and that the article should eliminate it, nor does it mean that the third bridge is sacred and should never be replaced on WP. Rather, I figure it should be relegated to a lesser status and the new fourth structure should start to take precedence. We keep the information about the third structure, add information about the first and second structures if anyone can find such information, and we add more information about the new structure as we can get it. Maybe we should organize these article in reverse chronological order, with the newest bridge first, the next recent bridge after, etcetera.

Lattice truss/girder bridges in the United Kingdom and Ireland (Britain, for short)

I have just completed an initial survey of these bridges, see http://en.wikipedia.org/wiki/List_of_Lattice_Truss_Bridges_in_the_United_Kingdom

This is an ongoing project, all my own work so far, and currently exists as stated solely as a Wikipedia list (which may not be appropriate but I am only a beginner).

This specific bridge sub-type can be encountered under a variety of names: open web, lattice, multi-lattice, Town, Macneill, etc etc. I will call them (at least for the time being) Town/Macneill lattices. The key defining features are a more-or-less fine mesh of diagonals lying at approximately 45-to-60 degrees to the horizontal top and bottom structural members; also no (or structurally insignificant) verticals.

My souce material has been almost entirely photographic, obtained mostly from Geograph, supplemented from WikiCommons.

I now feel that there is the basis of an article summarising the history of this specific bridge sub-type in Britain. They began to appear in Britain from about 1840, not that long after Town's US patent of 1820 for the wooden equivalent. They appear to have been 'imported' to Britain by John Macneill. The interesting point though is that other forms of girder were appearing concurrently, eg bowstring and - perhaps surpringly this early - plate girders.

The general form of lattice girder developed widely and rapidly throughout the 19th century. Yet the specific Town/Macneill sub-type just kept on going, new and substantial structures being built right up to at least 1910, the peak period being around 1870 - 1880. Why was this? Why, when iron and steel technology, and engineering mathematics, were advancing so rapidly, and a huge variety of truss forms were being evolving, was 1840 technology still considered the most appropriate for bridges such as the Kew Railway Bridge in London?

This project may not be totally in line with the concept of Wikepedia as an encyclopedia, as it might be said to involve research (though not original research) but I am going to try to do it anyway! I would really welcome the support of other WikiProject Bridges participants, particularly those in the UK or British expats, to turn this into an active article. Flying Stag (talk) 13:54, 10 April 2011 (UTC)

There's no mystery; the lattice-girder design was used in what were then the suburbs because it was cheaper than other designs of the same strength. Outside of the cities the ugliness wasn't generally an issue, and cutthroat competition drove the railways and tollbridge companies to use the cheapest designs they thought they could get away with. (In many cases such as Wandsworth Bridge it turned out to be a false economy as traffic increased with the growth of cities, and the cheap-and-nasty lattice trusses had to be knocked down and replaced.) Exactly the same happened elsewhere; there are plenty of box girder bridges throughout the Americas. In most of Europe the pre-1940 bridges were destroyed in the wars, so the pattern isn't as visible.
That said, the project you're describing sounds inappropriate for Wikipedia, unless you can find sources about the phenomenon rather than just a cobbling-together of passing mentions. Don't be surprised if it gets deleted under WP:SYN. – iridescent 14:53, 10 April 2011 (UTC)
Your patronising and ill-argued (not to say unintelligible and even offensive) response is just exactly what gets Wikipedia a bad name amongst beginners. Would some sort of positive suggestion lie totally outside your mindset, or do you find it easier just to issue threats? And I guess you haven't heard of the 'good faith' tag, or even a smiley. (I might then even ask you some sensible questions arising from your 'contribution', about which you might then provide me some sensible answers. Flying Stag (talk) 17:08, 10 April 2011 (UTC)
I am still trying to work out just exactly why you intervened on this page. My post was aimed at editors who had an interest in Wikiproject Bridges. You are not a registered participant, yet you claim to have some knowledge of the topic I am working on. So, come on, if you have useful knowledge to share (and it seems you do) please register and join in, so that we can share sources.
Having said which, so far you seem to have provided me with the answer to a question entirely of your own devising, viz: why cheap bridges were ‘knocked down’, which is sort of obvious. What I am really looking for was why the Town/Macneill multi-lattice was still being used as late as 1910. Not, I would think, primarily because it was cheap – if that were true, there would be none of the diverse trusses that had been devised by then. And if it was nasty, how come the ones still extant have survived. ‘Cheap-and-nasty’ is a bit too ‘pov’, and the survivors are splendid structures which will stand up to any objective assessment of niceness/nastiness (think Runcorn, think Kew). And what about Castlefield basin, a superb (and unplanned) coincidence of brick and iron structures forming one of the most dramatic pieces of three dimensional sculpture anywhere in the world (POV!), two Town/Macneill multi-lattices forming the core of this spectacle?
Your remark re pre-1940 bridges seems right off the wall! If there was a single major bridge in Britain which was destroyed beyond repair in WWII then this fact is not showing up anywhere on Wikepedia where I can find it, let alone anywhere else.
In summary, though I find your post pretty well incoherent, I would value some references to sources from which these rather simplistic views must emanate. I just hope that other Wikiproject Bridges participants are not too disconcerted by this inauspicious start. I look forward to hearing from you. Flying Stag (talk) 15:41, 11 April 2011 (UTC)

List page: removal of non-existant bridges??

My apologies if this intrusion is unwarrranted. There exists this list: List of bridges on the National Register of Historic Places in Vermont. I know for a fact that one does not exist anymore (destroyed) and one has moved. Is there a proper procedure to note this? Should the non-existent bridge be removed? What should be done about the one that has moved? — Preceding unsigned comment added by Srbergeron (talk • contribs) 23:56, 2 June 2011 (UTC)

Which bridges? The Bedell Covered Bridge is noted as "destroyed", but what else? - Denimadept (talk) 00:14, 3 June 2011 (UTC)
Er, that is, the BCB is noted as "destroyed" on its page. I've just now marked it as "(destroyed)" on the page you're talking about. It'd probably be better to discuss this there. There are other lists which include former structures, such as List of crossings of the Connecticut River, which might give you an idea of how this can be done, as well as the change I just made. - Denimadept (talk) 00:23, 3 June 2011 (UTC)

Luten arch

Can anyone tell if this uncited addition to Luten arch is actually accurate? The editor who keeps putting it back in is refusing to actually supply a source to verify what he claims it does, so I can't tell. The one link he supplied, in an edit summary, doesn't seem to agree with his addition, but I might just be misreading it.--SarekOfVulcan (talk) 00:17, 5 June 2011 (UTC)

I think he's trying to say that the Luten Arch is a tied arch. I see references that say the thrust created by the arch is offset by a tie (or tension member) below the waterline. If that's his intent, it's not well worded. - ¢Spender1983 (talk) 01:28, 21 June 2011 (UTC)

Bridge disasters

Just noticed that the Irk Valley Junction rail crash has been removed from Category:Bridge disasters (or a subcat) with the reason The bridge wasn't responsible and wasn't destroyed and was not the reason for any casualties, I would agree that the cause of the crash was a signalling failure (the bridge was not responsible) but I maintain that the seriousness of the crash and number of fatalities was directly related to the accident happening on a bridge - one carriage falling from it, so I believe it should be added back into the category. Any thoughts ? GrahamHardy (talk) 03:47, 29 June 2011 (UTC)

Simple. The bridge wasn't destroyed, and it's the kind of thing that could have happened on firm land with the same results. So it doesn't qualify as a bridge disaster. A truck falling off a highway bridge qualifies as a highway accident, never as a bridge disaster. -- Blanchardb -Me•MyEars•MyMouth- timed 01:35, 30 June 2011 (UTC)

Wikipedia:WikiProject National Register of Historic Places/Fall 2011 Photo Contest

WP:NRHP is having a Fall Photo Contest running from Oct. 21-Dec. 4, 2011. I'd like to encourage anybody who enjoys photography, as well as anybody who is interested in historic places to participate as a photographer, a sponsor, or both.

One way that an individual editor or a project can participate is to sponsor their own challenge. For example, somebody here might want to include a challenge such as "A barnstar will be awarded to the photographer who adds the most photos to the NRHP county lists of previously non-illustrated NRHP listed bridges." To sponsor a challenge all you need to do is come up with an idea, post it on the contest page, and do the small bit of work needed to judge the winner(s).

Any and all contributions appreciated.

  • At least three images, so that should justify a Commons category, linked from the article with {{Commons category}} and back-linked from Commons to the available wiki articles (if you link at least en:WP, then 'bots will eventually add any international interwikis). Blag the example code from another bridge article - I did Gaunless Viaduct last week, that should work.
  • Better photo! Bridge articles really need a side-on view, as it's very hard to understand a bridge otherwise.
  • Clarify what type of bridge it is. Is it a truss, beam or cantilever? (two of the Commons cats are wrong) If it's some combination, then explain this. If it's not clear what such a type means (and apart from simple stone arches, it rarely is), then give a structural paragraph in the bridge article that precis the structural description. This is easy to write, you can just lift it from the relevant and linked structural type article, but it's worth having it on the page in front of the reader.
  • Considering this bridge as a cantilever specifically needs explanation. The two central piers appear to be hinged, rather than rigid, so this is a very different sort of cantilever from the Forth Railway Bridge. Clarify that whilst the outer spans are presumably cantilevered (i.e. minimal load on the abutments), the central span might be seen (wrongly, as it turns out) just as much as a truss beam.
  • Clarify the truss type. Is this a Howe or a Pratt truss? Now this is hard, as it's a cantilever, not just a simple truss beam. The outer spans (as cantilevers) are the commonplace Pratt truss (diagonals in tension), but the central span (for a cantilever with hinged piers) is more complicated. Are these diagonals in tension too, or in compression? Is that central span a cantilevered Pratt truss, balancing the inner and outer spans, or is it a two-hinged arch? Ideally we'd find a source for this, but as a quick rule of thumb, the design of this bridge only makes sense if it's a cantilever, because only then would the diagonal placement make sense. If we compare it the the fairly common examples of a truss arch with truss side spans, then they use vertical bracing alone, as their arch structure would place no useful load into such diagonals.
Some careful writing here and you might expand this article into a good exemplar of the cantilevered hinged truss, as compared to the truss arch. That would make it a really useful and educational article, more than just a gazeteer entry. WP bridge articles need more of that - almost nothing is explained as yet, merely listed. (Mind you, then some ignorant idiot with a rulebook and no engineering understanding will probably come along and delete it, as WP:OR!)
  • Historical context. Was this a new bridge or a replacement? Was it built for a new route, or to add a new bridge to an old route? How did people cross the river before: nearby old bridge, ferry, or a big detour?
  • "one of only two" Footnote for where the other one is.

Please help get the UK's listed bridges ready for the start of the Wiki Loves Monuments competition on 1st September

In September the UK is taking part for the first time in the international photography competition Wiki Loves Monuments. Participants will be invited to submit pictures of listed structures of significant importance (eg grades I or grade II* or equivalent), as recorded by English Heritage, Historic Scotland, Cadw and the Northern Ireland Environment Agency . The main external website for competitors can be found here, and you can leave a message there if you have queries about competing. Do please join in, and let people in your local area know of this excellent way in which both existing and new Wiki users can help improve the encyclopaedia by contributing photographs of local listed structures. What about organizing a local Wikimeet to attract new people?

In preparation for the start of the competition on 1st September there is still quite a lot of work to do, and we would like to ask for the help of members of this wikiproject. Many of the listed structures are residential or other buildings, but there are a significant number of bridges that may be of specific interest to members of this project. Your local and expert knowledge will be invaluable in ensuring that the lists of eligible structures are up to date and correctly formatted. If you look at Listed buildings in the United Kingdom you will see how many structures are included. If you then follow the links, you can get to the detailed lists for your area. Alternatively have a look at the WLM planning table. Can you help to ensure that the lists for your area are up to date and well presented?

Some of the lists have been semi-automatically generated from data provided by the official listing organizations. These use pre formatted templates (eg EH header) which will make it much easier for competition participants to upload their photographs to Commons as an automated process. Please don't change the template structure, as we need to ensure that the templates are properly compatible with the WLM standards that are in use worldwide. The format will allow a bot automatically to collect the information and to put it into the international Monuments Database.

The data still needs the attention of local editors:

  • The "title" may need wikilinking to a suitable article name (whether we currently have that article or not). If there are several buildings in one street all of the wikilinks point at an article about the street; however each entry has a separate line in the list.
  • The "location" column looks and sorts better if just the parish or town is included (& wikilinked).
  • The "date completed" column sometimes has eg "C19" for 19th century, and "C1850" for c. 1850 when the date is uncertain - these need to be corrected manually.
  • The "grid ref & lat & long" (which is occasionally missing) may be given to 8 characters — only 6 (grid ref) or 5 (lat & long) are really needed.
  • Clicking on the "list entry number" should take you to the data sheet for that entry on the official database which can be checked if needed for details.
  • The image column should have a picture added if we already have a suitable image on Commons. (N.B. if you are going to be taking photos yourself for inclusion in the competition don't upload them until September)
  • References may be added according to normal WP practice.

For further information, please see Commons:Wiki Loves Monuments 2013 in the United Kingdom.

If you have any queries, please post them not below but on the Organizers' help page on Commons.

Anything you can do to help improve these lists will be much appreciated. The final deadline for cleaning up is 31st August.

Leaflet for Wikiproject Bridges at Wikimania 2014

Hi all,

My name is Adi Khajuria and I am helping out with Wikimania 2014 in London.

One of our initiatives is to create leaflets to increase the discoverability of various wikimedia projects, and showcase the breadth of activity within wikimedia. Any kind of project can have a physical paper leaflet designed - for free - as a tool to help recruit new contributors. These leaflets will be printed at Wikimania 2014, and the designs can be re-used in the future at other events and locations.

This is particularly aimed at highlighting less discoverable but successful projects, e.g:

• Active Wikiprojects: Wikiproject Medicine, WikiProject Video Games, Wikiproject Film

• Tech projects/Tools, which may be looking for either users or developers.

• Less known major projects: Wikinews, Wikidata, Wikivoyage, etc.

• Wiki Loves Parliaments, Wiki Loves Monuments, Wiki Loves ____

• Wikimedia thematic organisations, Wikiwomen’s Collaborative, The Signpost

The deadline for submissions is 1st July 2014

For more information or to sign up for one for your project, go to:

Just wanted to flag up the content that has recently been uploaded to commons as part of the National Library of Scotland's collaboration with Wikimedia UK. Three batches totalling about 250 images have been released. The photos include images of the construction of the Forth Bridge and the Tay Bridge disaster, about 130 images in all.

Hopefully some of this content will be of interest or of use to this project!

Cheers, ACrockford (talk) 12:54, 9 July 2014 (UTC)

Wikipedia:Sockpuppet investigations/Lswassa

Some of the bridge articles linked in the above sockpuppet investigation appear to be notable and could use some help. I did a little work on Cheong poong bridge, but I'm no expert on bridge articles. cheers.--Milowent • hasspoken 13:06, 24 July 2014 (UTC)

Standarization, Crossings as a sub category of Bridges, or vice versa?

Some (or all?) categories of lists of crossings are subcategories of lists of bridges (for example Category:Lists of river crossings in the United States is a sub cat of Category:Lists of bridges in the United States) I think it should be the other way around, every bridge (and ford, and tunnel) is a crossing.

Comment on the WikiProject X proposal

Hello there! As you may already know, most WikiProjects here on Wikipedia struggle to stay active after they've been founded. I believe there is a lot of potential for WikiProjects to facilitate collaboration across subject areas, so I have submitted a grant proposal with the Wikimedia Foundation for the "WikiProject X" project. WikiProject X will study what makes WikiProjects succeed in retaining editors and then design a prototype WikiProject system that will recruit contributors to WikiProjects and help them run effectively. Please review the proposal here and leave feedback. If you have any questions, you can ask on the proposal page or leave a message on my talk page. Thank you for your time! (Also, sorry about the posting mistake earlier. If someone already moved my message to the talk page, feel free to remove this posting.) Harej (talk) 22:47, 1 October 2014 (UTC)

Expert attention

This is a notice about Category:Bridges articles needing expert attention, which might be of interest to your WikiProject. It will take a while before the category is populated. Iceblock (talk) 03:12, 14 October 2014 (UTC)

WikiProject X is live!

Hello everyone!

You may have received a message from me earlier asking you to comment on my WikiProject X proposal. The good news is that WikiProject X is now live! In our first phase, we are focusing on research. At this time, we are looking for people to share their experiences with WikiProjects: good, bad, or neutral. We are also looking for WikiProjects that may be interested in trying out new tools and layouts that will make participating easier and projects easier to maintain. If you or your WikiProject are interested, check us out! Note that this is an opt-in program; no WikiProject will be required to change anything against its wishes. Please let me know if you have any questions. Thank you!

Note: To receive additional notifications about WikiProject X on this talk page, please add this page to Wikipedia:WikiProject X/Newsletter. Otherwise, this will be the last notification sent about WikiProject X.

Draft:Florida's National Historic Bridge

Can someone take a look at Draft:Florida's National Historic Bridge? I have been trying to help an IP edit the page. However, I can't find any references for the page. If it needs to be deleted, please do it. Thanks. Allen (Morriswa) (talk) 16:55, 8 February 2015 (UTC)

It was a hoax. To quote Imzadi1979: "Various versions of this draft article have used photographs of a bridge in New Jersey, stated that said bridge carries an Interstate Highway over a non-existant river in the Miami area, and changed the various dates of its supposed reconstruction. A quick look at a map will show that I-395 in Florida does not cross a river, let alone run between two cities called Atlantic City or Wheattown. This whole draft is a hoax." The same hoaxers made a string of others, see below. JohnCD (talk) 21:22, 13 February 2015 (UTC)

Recruitment Letter

Hello Wikipedians,

We’d like to invite you to participate in a study that aims to explore how WikiProject members coordinate activities of distributed group members to complete project goals. We are specifically seeking to talk to people who have been active in at least one WikiProject in their time in Wikipedia. Compensation will be provided to each participant in the form of a $10 Amazon gift card.

The purpose of this study is to better understanding the coordination practices of Wikipedians active within WikiProjects, and to explore the potential for tool-mediated coordination to improve those practices. Interviews will be semi-structured, and should last between 45-60 minutes. If you decide to participate, we will schedule an appointment for the online chat session. During the appointment you will be asked some basic questions about your experience interacting in WikiProjects, how that process has worked for you in the past and what ideas you might have to improve the future.

You must be over 18 years old, speak English, and you must currently be or have been at one time an active member of a WikiProject. The interview can be conducted over an audio chatting channel such as Skype or Google Hangouts, or via an instant messaging client. If you have questions about the research or are interested in participating, please contact Michael Gilbert at (206) 354-3741 or by email at mdg@uw.edu.

We cannot guarantee the confidentiality of information sent by email.

Hoax bridge draft articles

A string of hoax draft articles about bridges has been created over the last few days by user I Love Bridges1 (talk · contribs) (who I have blocked) and a number of IPs in the range 166.216.130.*, including:

None of them stood up to close examination - e.g. the roads concerned did not cross the relevant river, the description did not match pictures, and searches found no confirmation. This note is just to warn the WikiProject in case they try again. Looking at other edits from that IP range, I have seen edits to other bridge articles which have been reverted. Any bridge edit from a 166.216.130.* IP should be regarded with extreme suspicion. JohnCD (talk) 18:18, 13 February 2015 (UTC)

Lutherbrücke

I created a stub for Lutherbrücke, a bridge in Berlin. The German Wikipedia article has a lot of details, if anyone cares to translate. ---Another Believer (Talk) 14:08, 29 May 2015 (UTC)

Bridges in Chicago - articles needed!

If any project members are looking for new article to start, I've identified a few bridges along Chicago's riverwalk without Wikipedia articles:

I may get around to creating some of these when I have time, but others are certainly welcome to beat me to the punch. Happy editing! ---Another Believer (Talk) 15:24, 8 June 2015 (UTC)

Pulaski Skyway listed at FAR

I have nominated Pulaski Skyway for a featured article review here. Please join the discussion on whether this article meets featured article criteria. Articles are typically reviewed for two weeks. If substantial concerns are not addressed during the review period, the article will be moved to the Featured Article Removal Candidates list for a further period, where editors may declare "Keep" or "Delist" the article's featured status. The instructions for the review process are here. Imzadi 1979 → 01:50, 15 October 2015 (UTC)

Oławski Bridge

Oławski Bridge needs attention: it was clearly translated by someone with inadequate English knowledge, and the technical terminology includes links to nonexistent English pages. Please see Talk:Oławski Bridge#translation. --Thnidu (talk) 04:12, 2 January 2016 (UTC)

What do you mean by "links to nonexistent English pages"? I can only see two redlinks, both of which are clearly valid; the Oława is a genuine river (see Oder#Western tributaries), and pl:Alexander Kaumann is an obviously notable architect. It needs sourcing—which I'll leave to someone who can dig out the sources, which will likely mostly be in German for the construction and Polish for modern use—but other than that I can't see anything immediately wrong with it other than the term "blow" and the use of "cattle drive bridge" without giving the Polish name as well. (Any significant structure from 19th-century Breslau which has survived undamaged to the present day is pretty much going to be notable by definition.) ‑ Iridescent 16:08, 2 January 2016 (UTC)

Article: Bridge

Hi, I'm new to this project, and have joined because I have suddenly (!) developed an interest, particularly in respect of south west Wales, and the new article Cenarth Bridge. One of the project's principal articles, surely, is Bridge, but I found it littered with citation-needed tags, all placed at once in a hit-and-run quite a few months ago. I have dealt with some, but there are 11 left, some not so easy to eliminate. I'm sure this article could be GA without too much more work? Tony Holkham (Talk) 21:19, 3 February 2016 (UTC)

Wikipedia can't produce decent articles on broad topics. The editing model doesn't work for them.
My suggestion: don't even read it (it's really not much use). Write a new article from scratch. Make sure there is some sense of editorial narrative to it. Get the scope right and fill out the details. Decide beforehand what does need to be covered: how much of different types, how much of individual bridges, how much for engineering history of their development and innovations, how much for their cultural history. When it's done, read the old article and then see if there's anything there worth moving in. Then paste it over the top. Andy Dingley (talk) 22:29, 3 February 2016 (UTC)
What you say, Andy, does make sense. Thanks. Perhaps the article should just be a brief intro, then a list of types. Tony Holkham (Talk) 22:39, 3 February 2016 (UTC)

Are tunnels bridges?

Well, not normally. Someone just added Sapperton Canal Tunnel to this project, which struck me as extremely odd. Of course there are objects of such dimensions that it is hard to decide if they are bridges or tunnels, but not in cases like this. I suggest that if this project wants to include tunnels, the wording on the project page should be changed. Otherwise, (clearly defined!) tunnels should be removed. Imaginatorium (talk) 06:37, 24 April 2016 (UTC)

There are some cases like Eyre's Tunnel where there's a genuine discussion to be had about whether something is a short tunnel or a wide bridge, but this clearly doesn't fall into it; de-tagged. In reality it doesn't make the slightest difference to anyone whether a talkpage is tagged or not, since to the best of my knowledge nobody except the taggers ever cares. ‑ Iridescent 15:43, 24 April 2016 (UTC)
