Shortest segment

The distinction of "not crossing State boundary" does not make sense to me:

• Shortest segment not crossing a State boundary: 0.11 mi (0.18 km): I-95 in the District of Columbia, where it crosses the Potomac River on the Woodrow Wilson Bridge.[53]

Although DC is not a state, I would claim the particular I95-segment runs from the VA to the MD state boundary.

I thought quite a while about how to word this particular one -- how to be brief and yet still accurate. Before my edit, it read 'The shortest Interstate route segment within a state (or federal district)', which seemed a bit wordy. As the boundaries of DC with its neighbors are in fact the state boundaries of Maryland and Virginia, I thought the present wording was both accurate and concise. What about something like this:

• Shortest segment not crossing a State boundary: 0.11 mi (0.18 km): I-95 on the Woodrow Wilson Bridge across the Potomac River where it briefly briefly crosses the southernmost tip of the District of Columbia between its borders with Maryland and Virginia.

Or maybe someone else has a better way to express it concisely and accurately. Edit boldly! YBG (talk) 06:31, 30 August 2009 (UTC)

More about extremes

Because N-S routes are generally much shorter than E-W ones and major routes than not-divisible-by-5 ones, the information about I-10 and I-81 added by 76.189.169.77^{T / C} but undone by MPD ^{T / C} seems noteworthy to me. I'm willing to be convinced otherwise, but I'm inclined to restore it. But I am happy with the removal of the bit about grandfather clauses. YBG (talk) 06:24, 16 October 2009 (UTC)

The "not divisible by 5" qualification seems rather trivial to include. There are several major non-divisible-by-5 interstates which are quite a bit longer than others that are. I-30 and I-45 are rather shorter than, say, I-94, I-81, I-59, the eastern I-76, etc. etc. The only major distiction should be between the 2-d interstates and the daughter 3-d interstates. The whole "divisible by 5" thing is a bit too trivial. Ostebsibly, the "divisible by 5" ones are the longest, but there are too many exception in either direction to make it a big deal. Even if this stuff is true, its probably way to trivial to bother noting. --Jayron32 06:52, 16 October 2009 (UTC)

Would you agree that the distinction between N-S and E-W is significant to merit separate categories? YBG (talk) 06:56, 16 October 2009 (UTC)

Possibly. I-95 and I-90 as the longest NS and EW respectively probably bear mentioning, and possibly I-476 as the longest spur, but once we get to "longest not divisible by 5" or "most cars traveled on the third tuesday in may" or other such random trivialities, it can get to be a bit much. --Jayron32 07:01, 16 October 2009 (UTC)

I'm willing to concede thst longest not-divisible-by-5 may not be very notable ... they seem to be in the denser areas where there aren't as many numbers available. But might shortest-not-divisible-by-5 be a bit more significant, as the assignment x0 or x5 to a short route seems a bit more of a deviation from the plan to assign those numbers to coast-to-coast or border-to-border routes.

Exit numbers = mile markers

I had thought that changing exit numbers to match mile markers was a US national (federal) standard or guideline. I cannot find this. Can anyone help? Student7 (talk) 18:11, 24 July 2010 (UTC)

Distance-based numbering became mandatory in the 2009 MUTCD (Section 2E.31, page 32). Originally, I heard that all states have to comply with the change by 2020; however, the list of compliance dates on page 41 of the Intro and TOC PDF makes no mention of it. – TMF 19:56, 24 July 2010 (UTC)

Divided Highways

Just in case anyone is interested, the interstate system which are basically "divided highways" links to british variation of the term on wikipedia. The term "divided highways" links to "dual carriageways" on wikipedia. The term carriageway is not used by the majority of the international community. The term carriageway is very british centric, just like the term divided highway is very north american centric. So I have request a move of "carriageway" to "roadway" which is a neutral commonly used term throughout the world. Just thought some of you maybe interested in the discussion at Talk:Dual carriageway. UrbanNerd (talk) 23:07, 22 August 2010 (UTC)

References

The various references need to be cleaned up. I've started the first round, by templating them all and harmonizing formats as best as possible. Now all of the authors listed should be in Last, First orders, and all of the dates should be in US standard date format (Month DD, YYYY). Now, all of the missing information should be added. There are several links in there that are probably dead from link rot that should be fixed, several missing accessdates, publication dates, publisher names and author names. There are 60 current references, so it's possible that I might have missed one or two fixes in my initial pass, but we should take them all and get them cleaned up. For dead links, we either need to find replacement URLs, or find out if the pages were archived at archive.org in the Wayback Machine. If they're archived, then we can add the |archivedurl= |archivedate= parameters with the information to resurrect any dead links. As a goal, anything with an external link should have an accessdate added, even if that date is when the link was checked to make sure it still works. Imzadi 1979 → 03:18, 18 September 2010 (UTC)

Second minor thought, but while we're scrubbing the references formats, any that are from "roadgeek" sites, which are all technically self-published sources should be replaced with hihger-quality sources, online or in print. That will go a long way towards getting this article fixed up for any future GAN or FAC. Imzadi 1979 → 03:22, 18 September 2010 (UTC)

Split between federal and state

There was originally a split of funds between federal and state for construction. 90% federal, 10% state. This was deleted probably for lacking citation, also because it seemed to suggest that this was a current division of funding for maintenance, which it isn't. Anyway, now missing.

Extremes section

Should the extreme section be taken to a new article? It seems a bit unwieldly. Also, some do not have citations at all. IR393DEME (talk) 01:59, 2 December 2010 (UTC)

Yes, certainly references should be added where missing. I don't think this information deserves its own article, however. Items that are WP:TRIVIA or can't be verified should be deleted. Also, the use of bolding and the format ought to be rethought. -- Ssilvers (talk) 02:21, 2 December 2010 (UTC)

This is misleading. The National Highway system is 160,000 miles. The interstate system is just a subset of it. Senior Trend (talk) 01:10, 12 April 2011 (UTC)

This article is about the Interstate; so the statement in the first paragraph “making it both the largest highway system in the world and the largest public works project” is not true. Python eggs (talk) 17:59, 12 April 2011 (UTC)

Plus, expressways are no where near 160,000 miles in the U.S. Highway is a superset of expressway, which is a superset of the Interstate. I agree it is unfair to compare all Chinese expressways to the Interstate, but expressways is not highway. Python eggs (talk) 18:02, 12 April 2011 (UTC)

That's true. Maybe putting the NHS as the largest public works project and largest highway system is more accurate. Senior Trend (talk) 01:46, 14 April 2011 (UTC)

Re: First US state to complete main line of interstate highway

Please have a look at the construction subset paragraph of this article. Oregon completed its section of Interstate 5, the north-south mainline, in October 1966 with the opening of the Marquam Bridge over the Willamette River in Portland. Governor Mark O. Hatfield presided over the ribbon cutting ceremony. —Preceding unsigned comment added by 98.246.49.64 (talk) 17:31, 4 May 2011 (UTC)

However, Oregon has 3 mainline interstate highways, when were they all completed? I'm not that familiar with Oregon, but most states in the west did not have a reasonable complete system until the mid 1970s. Dave (talk) 15:56, 16 August 2011 (UTC)

America's Highways Reference

It may be of interest to the maintainers of this page to know that I recently posted a PDF copy of the 1977 Federal Highway Administration book "America's Highways 1776-1976" at the Internet Archive. This is a primary source used by most of the historical accounts of the US highway system. --BenFranske (talk) 06:51, 16 August 2011 (UTC)

Speed limit on interstate 10

A statute effective June 17, 2011, authorizes 85-mph speed limits in Texas, although the new law requires traffic and engineering studies before the higher limit takes effect. This also gets rid of the 65MPH night limit in Texas as well.DEWY CHEATEM AND HOWE (talk) 09:32, 9 November 2011 (UTC)
