In talking with someone at AASHTO, they provided a link to look at past Interstate, U.S., and Bike Route applications. In perusing through some of the applications and correspondence, I found some pretty interesting ideas.

Among them are:

US-78 extension to Denver, CO circa 1954

US-24 extension to St. George, UT circa 1955

US-200 establishment between Missoula, MT and Duluth, MN, circa 1961

US-64 extension to California via a lengthy concurrency with US-66 (1933 correspondence)

There are also other applications/correspondence that we know about as well. I canít seem to get direct links to the individual applications, but here is the link to the database:

Just enter in the number, state, and/or year youíre looking for and you should be able to find these documents pretty easily.

Nice! This sheds some light on what the hell actually happened with US-377 in Oklahoma, where, before, all we knew was there was a string of applications that were rejected. Turns out that Rep. Wes Watkins had been the one trying to get the extension done (at the behest of a local Highway 99 Association). AASHTO at the time had a point-scoring system and 377 never reached the required score (based on quality of the road, perceived over-density of US routes, being rejected before, and the designation being pushed by someone outside the highway departmentódefinitely not a criterion that would stand up in the modern day!)

What we do know is that in 1988 ODOT mysteriously started posting US-377 without AASHTO approval, as noted in their own documentation. So prevailing wisdom has been that was an instance of ODOT being ODOT and not playing by the rules. Turns out the truth is much less interesting...Wes Watkins wrote the designation into the Department of Transportation and Related Appropriations Act, 1988 (which was signed in December 1987). ODOT to submitted an application to AASHTO for rubber-stamping. AASHTO disapproved it in June 1988. ODOT shrugged, looked at the law, and posted the signs anyway. Can't say I blame them.

Oh, by the way, according to the bill, the official terminus of US-377 is at I-44, not OK-66. Oklahoma just sucks at road signs.

I wonder who was the shortminded who proposed the number I-238 without checking if there was a I-38 first. Oh, wait...

I like how Texas, New Mexico and Arizona tried to extend US 90 all the way to San Diego. California, on the other hand, didn't got along as they couldn't find a suitable alternate to US 80.

Oh, and I like how Rand McNally really cared about route numbering. Surely they didn't release their road atlases in April back then.

I believe it was a CA state route and they didn't want another I-x80.
