Talk:List of auxiliary Interstate Highways/Archive 1

Contributions
Hi all 3di contributors

I was wondering if:
 * Any way to section this list into separately editable sections, since this list is getting so big? (Haven't found any related templates yet.)
 * Thanks Bkonrad.  Bwefler 19:05, 6 Mar 2005 (UTC)


 * Want to collaborate & divvy out who does 3di's from which primary interstate? So far I have done (hopefully completely) the 3dis for many interstates involving western states, Texas, and some Midwestern states (and others I'd "call'em as I see 'em?")
 * I'll take I-24,26,30,40. talking to myself here ... Bwefler 19:30, 6 Mar 2005 (UTC)


 * Any other suggestions?

Thanks. Bwefler talk 17:46, 6 Mar 2005 (UTC)

I-805
Isn't the 805 a connector between I-5 and I-8 and hence the name? (I know the Interstate system relies on the list two digits for the main Interstate it associates with, but I think there could be a mention of I-8 here.) RickK 00:50, Mar 8, 2005 (UTC)


 * Maybe save that for a historical section or something ... Bwefler talk 03:05, 8 Mar 2005 (UTC)


 * The 8 in the name is pure coincidence; it was the fourth even 3DI off I-5 (after 205, 405 and 605). --SPUI (talk) 22:09, 8 Mar 2005 (UTC)
 * I-805 is actually I-5's bypass of San Diego downtown. --17:07, August 10, 2005 (UTC)

A couple notes
We should link to the pages for the Interstates. I've been working on separating them into pages (which I've done for the I-95 spurs). So we should link to I-295 (FL) for instance, and if necessary put up a temporary redirect to the main page.

Unbuilt Interstates and old numbers should be included, but we need a line to keep stuff like I-102 out. I propose the following:
 * 1) Don't list it if it was renumbered by 1959, when the routes were signed.
 * 2) Don't list anything that was quickly renumbered, UNLESS the number was used by non-internal sources (like newspapers).

This goes without saying, but no I-394 (MI), no I-875 (MI), etc.

I think we should sort the states by order served along the parent, from south to north and west to east. Maybe sort the 3DIs by where they spur from the parent. --SPUI (talk) 22:42, 8 Mar 2005 (UTC)

Ref's need full state names to avoid redirects
SPUI:

I appreciate your efforts, but I have been spelling out the state names in the city article links to avoid redirect messages. (See in the history, NiteOwlNeil's note.)

Bwefler 02:58, 16 Mar 2005 (UTC)


 * Redirects are there to use, and to make life easier. This way you can simply type I-295 (RI) and get I-295. --SPUI (talk) 01:18, 16 Mar 2005 (UTC)

Significance?
What is the significance of three-digit highways? Why have a list of these, separate from other highways? The introduction to this article should address these questions. I suspect three-digit highways are different from regular highways in some way ... dbenbenn | talk 09:54, 27 Mar 2005 (UTC)
 * These are meant to be less major spurs from the more major two-digit ones. Having these in a separate list keeps the 2-digit list from getting cluttered. --SPUI (talk) 10:51, 27 Mar 2005 (UTC)
 * Also, for example, I-180 is different from all other interstates since it has traffic signals almost everywhere. No other interstate can make that distinction, and it is also the shortest interstate.  Vishwin60 03:47, 28 September 2006 (UTC)

Trivia

 * Found an even shorter one I-315 Justin 22:56, 13 January 2007 (UTC)


 * There was an error on the trivia I-878 is the shortest unsigned interstate at 4.93 miles. But I-478 in NY is only 9,000+ feet. Justin 22:29, 13 January 2007 (UTC)
 * I-878 is 0.70 mi, so it is the shortest interstate. I-478 is 2.14 mi, according to the FHWA. V60 VTalk - VDemolitions 21:53, 3 February 2007 (UTC)


 * I removed the trivia section completely as it's inappropriate for a list article, all the info is already found elsewhere (mostly at Interstate Highway System), and the info that was there was inaccurate and contradictory anyway. Krimpet 04:52, 6 February 2007 (UTC)

Table Completed!
The table of the List of auxiliary Interstate Highways is now officially completed! Artisol2345 16:56, 17 August 2007 (UTC)
 * The list is also completed! However, I am willing to fix any inaccurate information and have the article conform to the highest qualities. But if you have any need to fix anything else, please do so. Artisol2345 00:47, 10 September 2007 (UTC)

Improve list
How do you all think we can organize the table a little more? 68.101.124.142 01:14, 26 September 2007 (UTC)

More Information?
This article has too little of information for an article that has a long list. 23:23, 27 September 2007 (UTC)

I have a new proposal!

Hi! I've been wroking on remaking the table and try to make it look neater. I want to hear what you all think about it, and if you think it's better than the current table. So here is a sample on Interstate 5... 01:53, 26 October 2007 (UTC)
 * I don't like it. The font size is excessively large and the background coloring is unnecessary. -- T M F Let's Go Mets - Stats 02:21, 26 October 2007 (UTC)
 * Well it's the same standard coloring used in Interstate infoboxes. The colors are what separates the Interstates into its proper categories. Also, I don't know if I made any font size bigger, but it's been that way. In fact, I made the fonts for the states smaller. I want to hear more people's opinions, though...  02:59, 26 October 2007 (UTC)
 * In the cells containing information about each route, the text is most definitely larger in your "remake" than in the existing list. -- T M F Let's Go Mets - Stats 03:04, 26 October 2007 (UTC)
 * The font is too big. --Rschen7754 (T C) 03:06, 26 October 2007 (UTC)
 * So if I were to make the text smaller, what whould you still think about the remake?


 * Also, I put colors on the current table signifying an unsigned or future auxiliary route. I think it should have different colors; one that sticks out less. (Right now, I can't find such color.)  03:14, 26 October 2007 (UTC)


 * Actually, I found an error in the coding, fixed it, and made the text smaller. Now what do you think? What other adjustments do you think I can make?  03:16, 26 October 2007 (UTC)

If another reason is needed to not add colors to the list, consider this: with little extra code in the existing list, the size of the page is a painfully large 105KB, which takes forever to load as it is. Who knows how many more bytes will be added if colors are added to the entire list. -- T M F Let's Go Mets - Stats 03:23, 26 October 2007 (UTC)


 * It's only 105KB based on the amount of characters in the text area on the editing page of the article. It would greatly reduce the number of characters if we use templates to shorten up the coding.


 * Just for the record, I like articles over 100KB. :) Besides, there are so many lists larger than this one. You can always try List of terrorist attacks (over 200KB).  03:33, 26 October 2007 (UTC)


 * That doesn't give this list permission to be gigantic. My guess is that some users that click on this list probably cancel loading due to the huge load time for the page. I do, anyway. Because of the hefty size, I really don't find the current list, or the proposed "remake" above, useful, tbh. If I want to find an auxiliary Interstate, I'll just use the state highway lists by state, which often include interstates in that state. -- T M F Let's Go Mets - Stats 03:44, 26 October 2007 (UTC)


 * No duh, I said for the record. Sorry if I was harsh, but I never said I wanted the list to be gigantic. If no ( what you call "consensus") can be reached, then would any of this matter at all?  04:10, 26 October 2007 (UTC)


 * And, if you really believe that this list is extraneous and you use the Interstate Highways list, why was this page created in the first place? More importantly, who started with the table to organize the information? (Yes, I know, I finished the table when it was half-way completed.) Few more questions that some people would want to figure out.  04:21, 26 October 2007 (UTC)

What is the problem with the current list? --Rschen7754 (T C) 03:28, 26 October 2007 (UTC)


 * Well to me, nothing's wrong, really. I'll just stay on with the current list. Something sparked me an idea of a new table, and I wanted to see if editors find it acceptable. For now, I'm guessing it's a no.


 * However, there is another problem when I tinkered with the code on the list. I included additional colors in the current list, and as I mentioned above, someone should replace the colors and find the ones that don't stick out so much.  03:33, 26 October 2007 (UTC)
 * If it ain't broke, don't fix it  master son T - C 12:19, 26 October 2007 (UTC)

The colors are a bad idea. What we really should do is make something sortable. --NE2 06:47, 27 October 2007 (UTC)

Change from [[Image:AA-BB (CC).svg]] to
Somebody has start changing from to , stop after i-35 section. If people wants to do it they do it to all of them. I now have to dig it through and start fixing it. Plus this page is almost 100 KB long-- Freewayguy  Msg USC 00:58, 21 June 2008 (UTC)

"I-38 does not exist..."
Hey all -- Since Interstate 38 does not exist, I recommend that I-238 be listed under heading "Other" or "Orphan."

Thanks -- Bwefler (talk) 17:53, 14 Mar 2005 (UTC)


 * Object - someone looking for I-238 would see the pattern and look for it between 35 and 40. --SPUI (talk) 18:29, 14 Mar 2005 (UTC)

I agree with the move idea and have done so WP:BOLDly... Interstate 38 doesn't exist and listing it would just confuse people. 238 should be listed in a section describing what it is, an exception. It's not a typical 3DI but neither is it a primary interstate.Gateman1997 20:24, 25 January 2006 (UTC)
 * I agree with moving it, however, I'd put it under I-80 (IIRC they ran out of numbers in California), then make a note of why it's an exception to the format. Just my $.02. Mtndrums (talk) 09:39, 19 February 2010 (UTC)
 * Only issue I'd have with that is strictly speaking I-238 is a not an auxiliary interstate of I-80 either. If they'd intended it to be they easily could have changed the number in recent years to 480 but they've yet to do so which seems to me to indicate they do not intend it to be an aux of 80. For now it does just remain an exception to the general rules. Gateman1997 (talk) 18:23, 19 February 2010 (UTC)

Interstate 870
Is this possible I-870 ever been plan in history? Maybe i don't see any valid source saying so.-- Freewayguy  Msg USC 00:51, 21 June 2008 (UTC)

It was floated around during the 1980s as I-255 was under construction in Illinois but it was not used. There was quite a bit of public comment on the I-270 Draft EIS that was made in the early 1980s. Kimmy78 (talk) 03:55, 14 February 2011 (UTC)

Page edit hits 60-second timeout
In October 2013, several people studied the long reformat time of "List of auxiliary Interstate Highways" which often exceeds the 60-second timeout limit and hits "504 Gateway" error or "wp:Wikimedia Foundation error" (8 times during editing on 27 October 2013). There are 3 major templates used over 100x times:
 * Template:Roadlink - used 472 times, runs over 35 seconds
 * Template:Jct - used 228 times, runs over 21 seconds
 * Template:Convert - used 116 times, runs about 3.5 seconds

To reduce the total reformat time, 2 faster templates have been used:
 * Template:Roadlink/USA - used 472 times, runs over 18 seconds
 * Template:JctI - used 228 times, runs over 2 seconds

However, the total time is still over 26 seconds and risks a timeout on slow servers, unless reduced closer to 20 seconds or below. If many road names were changed to simple wikilinks, to avoid {roadlink...}, then the edit-preview time could be faster. -Wikid77 (talk) 23:43, 27 October 2013 (UTC)
 * All of the roadlink calls can be switched over, all of them. In fact, I believe that is in progress.  Imzadi 1979 →   23:56, 27 October 2013 (UTC)
 * And they are gone.  Imzadi 1979 →   19:23, 28 October 2013 (UTC)

Conversion to templates
This table should be converted to use the templates from WP:USRD/STDS/L. In the process, the gray color will be switched from unsigned highways to former highways. In the interim, I updated the color key to indicate that the gray color is for former highways. In the future, unsigned highways should be noted with a note, the lack of a shield, or both.  Imzadi 1979 →   01:15, 23 November 2014 (UTC)
 * The table has been converted to use the templates. In the process, the List of future auxiliary Interstate Highways and List of unsigned auxiliary Interstate Highways were both merged in. In the latter case, all of the entries were present already. In the former, that list was out of date, and only a few entries had to be moved over. Since most of the future 3dIs were already here, there was no need to maintain parallel lists and let them get further out of sync.
 * In the process, a few former 3dIs that weren't listed have been added, restoring I-164 back into its proper place on this list. The table is incomplete. I will list the cleanup tasks in another section.  Imzadi 1979 →   07:54, 23 November 2014 (UTC)

Table clean up
The following needs to be done:
 * Dates need to be added.
 * Lengths should be double checked against the most recent FHWA Route Log and Finder List, and they should be updated so every entry possible has a length to 2 decimal places.
 * In doing so, I-275 in Michigan will need it's official MDOT length added as a note because FHWA's length does not match what the signs and maps show.
 * Cities need to be cleaned up so that have state names We can display the postal abbreviations to conserve space in the table.
 * Now that the table is sortable and lacking section headers for each 2dI and faux headers for the states, we need to make sure that each line of the table is linking to the connecting highways.
 * In linking to other highways, we really should be bypassing redirects so that non-American readers can hover their cursors over the abbreviations to get full names.

You'll note that I mention bypassing redirects and piping links. In the first line of the table, we we link "H-1" to "Interstate H-1", so if a reader is confused by the "H-1" abbreviation, he or she can hover his/her cursor over the link and a tooltip will display with the full name, "Interstate H-1". If that same reader attempts to do the same with "SR 1" in the next line, he or she will be greeted with a cryptic "SR 1 (CA)". We assume our readers will know that "SR 1" equals "State Route 1", and that they will know "CA" equals "California", but that is not a valid assumption to make on a global publication like Wikipedia. However, if we link to "California State Route 1", that is a useful expansion of the abbreviation. We're also missing state names in this initial conversion, so they need to be added. For similar reasons as the highway designation abbreviations, if we pipe a link to "El Segundo, California" so that it appears as "El Segundo, CA", readers can use the tool tips if they are not familiar with the various state postal codes.  Imzadi 1979 →   08:10, 23 November 2014 (UTC)

Couple Unrelated Questions

 * 1) For Interstates under construction, should the finished length or current length be put underneath the length column? For example, Interstate 369 in Texas has a current length of 3.50 miles. Should we put 3.50 miles under the length column, or should we put the finished distance, which would most likely be much longer?
 * 2) Interstate 265 is considered a single Interstate, even though it has two separate segments in both Kentucky and Indiana. Should this be in two separate columns (like it currently is), or be merged into one single column? Will211 (talk) 07:03, 6 February 2016 (UTC)
 * Replies:
 * I've updated all of the lengths in the table off the most recent FHWA Route Log and Finder List and cited entries in the table that do not appear in that document. I would go with the current length open to traffic, which is what FHWA would list. If necessary, we need to add explicit citations in a length_ref for specific rows of the table.
 * For the moment, I'd leave them separate until they merge together.  Imzadi 1979 →  14:29, 6 February 2016 (UTC)

I-164 request
Technically I-164 still is designated in IN, all but 0.69 miles were taken by I-69 (coincidentally). I updated to reflect that but was having trouble including the reference for the change new mileage because I'm no Wikipro. Here's the info from the I-164 page that I couldn't get to show up without errors. Can I get an assist? I'm hoping this change will be acceptable since it's accurate and now makes I-164 the shortest 3di. Thanks.Bodo920 (talk) 08:04, 20 November 2016 (UTC)

Why we only need 3 examples?
I've searched this article for a long time but I still didn't why we only need 3 examples for each types of auxiliary Interstate Highways. 2606:A000:6205:B300:5C0D:8B17:E157:1605 (talk) 15:22, 4 July 2018 (UTC)

 * Examples in threes is a common rhetorical device in writing.  Imzadi 1979  →   17:17, 4 July 2018 (UTC)

FHWA site redesign
Some pages on the FHWA website have been moved. For example, http://www.fhwa.dot.gov/reports/routefinder/index.cfm#s09   has moved to https://www.fhwa.dot.gov/planning/national_highway_system/interstate_highway_system/routefinder/index.cfm#s09   I have made the change in this article, but editors revising individual highway articles should check all FHWA links on the page of interest to see if they have moved. Also, be careful not to add FHWA redirects that point to a more general page, rather than to a page with the same information as before. Eastmain (talk • contribs) 07:19, 8 June 2019 (UTC)

List sorting
I'd like to propose changing the sorting of this list from strictly geographic to numerical then geographical. It makes no sense to me that I-105 (CA) and I-105 (OR) are not next to each other in the list. –Fredddie™ 16:02, 24 April 2021 (UTC)

Where is Interstate 214?
> 84(C): Following portions of US 190 eastward, passing near the central Texas cities of Fort Hood, Killeen, Belton, Temple, Bryan, College Station, Huntsville, Livingston, Woodville, and Jasper before connecting to SH 63 at the Burr's Ferry Bridge where it becomes LA 8 at the Louisiana border. This route includes a loop generally encircling Bryan–College Station, Texas designated "I-214".

> I-14 in Texas is proposed to have one auxiliary route, Interstate 214, which would serve as a loop for Bryan–College Station metropolitan area.
