The California WikiProject does not have any particular article guidelines, but if check, some of the related WikiProjects, such as Wikipedia:WikiProject Cities do have guidelines and suggestions. There is also all of the material in the Wikipedia Manual of Style.
The other thing to consider is what is the basic information that a reader of the article needs to know. For example, for the bridge articles that you mientioned: I assume that there is a road or train track that crosses the bridge, but the articles make no mention of that (Rocky Creek Bridge mentions PCH, but Bixby Creek Arch Bridge doesn't). The articles also need to mention which county they are in, and which cities they are near or between. If you can find out the information, you should mention who maintains the bridges (state, county, or city), and if there has been any earthquake retrofitting done to the bridges (and when). If you know anything about Bixby Creek and/or Rocky Creek, you should add that info. BlankVerse 09:00, 2 November 2005 (UTC)
