Talk:List of state routes in Illinois

Table of Illinois Routes
I'm going to start a table of routes that contains more useful information on the lists page... starting with 1-10 and seeing how it looks. Comment here about its usefulness. &mdash; Rob (  talk  ) 02:43, 18 April 2006 (UTC)

General guidelines for regions
These are guidelines, not rules!


 * North: North of Interstate 80
 * South: South of Interstate 64
 * West: Western 1/3rd of state... roughly W of a N-S line through Peoria
 * East: Eastern 1/3rd of state... roughly E of Illinois 47
 * Central: Anything within Interstate 72, 74 and 155
 * North central, etc: Use your own discretion, in accordance with above guidelines.

-- IDOT goes a bit different on regions:


 * Northeast: Chicagoland region, or anything North of I-80 and East of I-39
 * Downstate: Anything outside of Chicagoland

A lot of the politicans in the state (especially ones in Chicagoland) go on this belief as well.

Refocusing
I have split content from this list out to form Illinois State Highway System, so that this page can focus on being a list of the state-level routes in Illinois. We now have List of Interstate Highways in Illinois and List of U.S. Highways in Illinois to accompany this list as well.  Imzadi 1979  →   08:54, 25 April 2014 (UTC)
 * Going forward, the list should be converted into a table per WP:USRD/STDS/L using the newer templates for that task, which is how the other lists were done when they were created.  Imzadi 1979  →   08:58, 25 April 2014 (UTC)

Route Number Formatting
I would like to go thru the page and format the route numbers to "IL-42", "KY-492" etc., with the 2 letter state code, a dash and the number. Is there a Wiki formatting guideline for this that supports or denies this format? I would hate to go thru that kind of work and have it all reversed...N9jig (talk) 03:01, 5 January 2016 (UTC)
 * each state has a standard abbreviation in use in the jct template. For most of them, they lack a hyphen, and they are not based on the two-letter postal abbreviations unless that is what is in use in that state. For example, it is "IL 42" for Illinois and "KY 492" for Kentucky, but in Indiana, it's "SR 1" and for Wisconsin, it would be "WIS 32". We also recommend the usage of non-breaking spaces for the spaces in abbreviations so that the letter portion (the "IL", the "KY", the "SR", etc) can't appear on one line before a linebreak while the numbers appear on the next line. ( has coding in place so that this can't happen, even with hyphenated abbreviations).
 * While what you propose to so sounds like a general improvement by making this specific article internally consistent, it would make it inconsistent with other articles on Wikipedia.  Imzadi 1979  →   03:14, 5 January 2016 (UTC)
 * To make it easier so that editors don't have to dig through the various testcases pages for jct or consult other articles, there is now a column listing the abbreviations at WP:USSH.  Imzadi 1979  →   03:45, 5 January 2016 (UTC)

Temporary and Special Routes
The routes listed as "Temporary" and "Special" Routes are nothing of the same. IL-113N and IL-113S were permanent route numbers that got changed later, as were the appended routes like IL-1A etc. The "Special" routes should list the various bannered routes like "Business" "Truck" "Spur" etc.

These should be integrated into the Route List as they were as "Former Routes" and thus highlighted in grey.

At the time they were posted they were not intended as temp or special routes, IDOT just changed their mind down the road.

I would make the changes myself but I am not versed in Wiki tables. If there is no volunteer to repair this I will tackle it later. N9jig (talk) 21:27, 21 July 2016 (UTC)
 * Done. Were there ever any "temporary" numbers that weren't bannered?  Maybe some of the above-200 ones assigned in the Chicago suburbs because someone was sure an Interstate designation was coming? --Closeapple (talk) 02:25, 22 July 2016 (UTC)


 * There were some "Temporary" route placements here and there but they were short lived and not well documented. Most of the route numbers were not intended as placeholder numberings in that sense.N9jig (talk) 04:33, 22 July 2016 (UTC)
