Lake Shore Drive Bridge[edit]

The Outerlink Drive Bridge built in 1936 was replaced some years ago with the current Lake Shore Drive Bridge and are not the same bridge. The current bridge was built to replace the much hated "S" curve which was a poorly built piece of road that was a dangerous traffic hazard. —Preceding unsigned comment added by (talk) 03:38, 22 May 2008 (UTC)


"This contributed to several public health issues including a major cholera epidemic. "

Can someone cite a source for this? According to , there was no cholera epidemic.

Article changed. Thanks for pionting that out. Rmhermen 16:45, 31 July 2006 (UTC)

St. Patricks Day[edit]

I moved the thing about dying the river on St. Patricks day to the top. I'm not sure if this is the best place for it or if a new section should be added. A special events, or holiday section perhaps. I don't know enough to do it myself though, and a new section wouldn't seem necessary for such a small amount of info. Jack Lumber 21:01 10 August, 2005

It doesn't need its own section. I did put a mention of it in the new intro I wrote, though. --Dhartung | Talk 06:43, 11 August 2005 (UTC)
"The secret ingredients used to dye the river green today..." Is it really likely that whoever dyes the river is allowed to keep the chemicals they use a secret? Surely they must be EPA approved? Rawling4851 13:40, 18 May 2007 (UTC)

There's no evidence that dumping flourescein is illegal. See It can reach a concentration of 30 mg/L, according to the State of Michigan. I was at the dyeing today, and the substance looked exactly like this flourescein (see the MSDS on the page),, i.e., an orange powder. This page,, says they use 25 lbs to dye the river (and there's no reason to think they don't use less now). If my calculations are correct, 25 lbs is diluted to 30 mg/L in a cube 25 ft on a side (coincidentally). That's not a large volume. They're dispersing it over an area about 500'x100' (see,-87.617726&spn=0.005591,0.00912&z=16&source=embed). I think they're using flourescein. —Preceding unsigned comment added by (talk) 04:04, 15 March 2009 (UTC)

Reverse River[edit]

This article says that the river was reversed in 1900 into the ship and sanitary canal by the chicago sanitary district. The Illinois and Michigan Canal article says it was reversed in 1871 into that canal by the army corps of engineers. Which is it? Rmhermen 22:08, Oct 8, 2003 (UTC)

The river was partly reversed in 1871 into the I&M Canal, yet usually still flowed naturally, with the reversal occuring after heavy rain. In 1900 the River was permanently reversed into the Sanitary and Ship Canal, with it always flowing backwards, as it does to this day. Dralwik 01:54, 26 Mar 2005 (UTC)

The source that indicates the river still flows naturally beneath the surface, is now dead. I think this research needs to be located or that section should be removed. —Preceding unsigned comment added by (talk) 02:17, 28 July 2010 (UTC)


I uploaded the following images: Image:Chicago River dyed green, focus on river.jpg, Image:Chicago River dyed green, buildings more prominent.jpg, and Image:Chicago River, dye travelling upstream.jpg. I wasn't sure which images to put here and in St. Patrick's Day; feel free to switch them around. — Knowledge Seeker 07:36, 13 Mar 2005 (UTC)

I'm adding my picture of the Chicago river at night, but I fear it might be redundant. Opinoins? -- BMIComp (talk, HOWS MY DRIVING) 23:41, 23 July 2005 (UTC)

Ecology of the Chicago River[edit]

At the very least, it needs to be touched on at some point. I'm sure Friends of the Chicago River or the Park District has some history, but I myself know very little about the river's ecology.

I agree. We also need to mention the recently completed "Deep Tunnel" project, which has had a positive effect on the river that can hardly be overstated and which is now a model for other cities.

What about boating?[edit]

Something should be added about recreational boating on the river. Launch sites? Types of boats allowed? --Kalmia 06:03, 13 July 2006 (UTC)

In addition to recreational boating, how about something on the existing riverwalk and future plans? —The preceding unsigned comment was added by (talk) 18:20, 3 March 2007 (UTC).


What's the deal with the blatant plagiarism of the following article from the Fairfield Mirror in the "St Patrick's Day" section? The information is practically copied word for word out of the article with no references or credits given whatsoever? I added one reference but when I found out the entire thing was ripped out of the article, I think it's best if the section is rewritten without stealing other author's works.

pctures in the "bridges" section[edit]

These pictures have been edited to the point of being just silly - way too much contrast and saturation. What's the best way to find replacements? Alphachimera (talk) 19:23, 6 July 2011 (UTC)

Picture of the day
Chicago River

A view west along the main stem of the Chicago River, a system of rivers and canals that runs through Chicago, Illinois, US. Though not especially long, the river is notable for being the reason why Chicago became an important location, as the link between the Great Lakes and the Mississippi Valley waterways. Buildings such as Trump International Hotel and Tower in the center and Aqua (gray building with turquoise "streak") are among the prominent structures depicted. On the right is the cleared land that was awaiting redevelopment as the Chicago Spire. This photo is from the Link Bridge with the Streeterville region of the Near North Side community area to the north and the Lakeshore East and Illinois Center regions of the Loop to the south.
