My family went on a vacation to Washington DC in 1982, using that route to travel there. I do not remember how far east the US 48 designation was signed into Maryland, or if it was co-signed with US 40 anywhere along the route. In December 1990, my dad, brother and I went to a few places along the east coast and we came home via that route. They were finishing up the freeway construction between Cumberland and Hancock at the time, but again, I don't remember how much of the route was signed as US 48.

I drove U.S. 48 (end-to-end) from Hancock, Maryland to Morgantown, West Virginia  in 1983.  The freeway was complete then from the Cumberland Thruway (I think it was present-day Exit 46) section west all the way to I-79.  IIRC, it was signed as U.S. 40/U.S. 48 from Hancock to  Keyser's Ridge (present-day Exit 14), where U.S. 40 left the freeway headed west and north toward Uniontown, Pennsylvania (as it does today) and U.S. 48 continued on a relatively straight westbound path toward Morgantown and I-79. 

East of Cumberland, there were two freeway segments of U.S. 40/U.S. 48 that were completed long before the entire freeway between Cumberland and Hancock was open to traffic.

The first freeway segment (headed eastbound) was in eastern Allegany County and included the interchange at Little Orleans Road (the structure that carries Little Orleans Road [Exit 68] over I-68 is distinctly older looking than most of the other bridges along this part of I-68).

The second freeway segment was in western Washington County, between the MD-144 interchange (Exit 77) at the eastern foot of Sideling Hill and the east end at I-70 (I-68 Exit 82).

Aren't we due for a US 437?

What?

400, 412 (412.5 rounded down), 425, next is supposedly 437.

Why isn't 412 related to 12? Couldn't they have named it some other number? Same with 425.

I'm guessing at the time, AASHTO was more preoccupied with the Interstate system, and when states requested new US routes, they just started issuing 4xx ones, due to indifference. Nobody aside from road geeks really care, so long as it gets them from point A to point B. I think AASHTO has finally snapped out of that, though.

I agree with AASHO/AASHTO being preoccupied and indifferent with regard to the US route system.  However, I think they started getting out of the business of assigning designations in the '70s, before the infamous 4xx routes were created.

Starting in about 1960, as more and more Interstates were opening to traffic, many state highway departments started truncating and/or decommissioning their parallel US routes.  Obviously the Interstates had become the exciting new development, whereas the original "interstate highways" (the US routes) were considered outdated and obsolete.  As an association consisting of state highway officials, it's not surprising that this mindset soon manifested itself within AASHO (which became AASHTO in 1973).  It was during this general timeframe when AASHO/AASHTO became more apathetic as far as assigning new US route designations, instead shifting towards letting the states come up with their own designations.

*1963: US 259 was one of the last new designations free of controversy.
*1966: US 164[ii] did not connect with US 64.  I suspect (but have no proof) that AZDoT wanted it to be US 64 (since it had been AZ 64).  AASHO wouldn't allow that, since (at that time) it did not connect with the existing US 64, so 164 was a tolerable alternative.
*1970: US 163[ii] is nowhere near US 63.  My understanding is that AZ and UT originally wanted 164[iii], probably since 164[ii] was going to be decommissioned that same year, but since it was a north-south route, AASHO told them it needed to be an odd number.  However, instead of assigning a more logical number, AASHO allowed AZ/UT to simply subtract one integer to come up with "163".
*1970: US 57 is a single-state US route, running east-west but with a north-south number.  This route had been TX 57, and it connects with Mexico 57.  It seems Texas felt it should be a US route, and AASHO allowed them to keep using the same number 57.
*1973: US 48[ii] was an acceptable designation.
*1982: US 412 is nowhere near US 12.  I assume AR and TN came up with the number, but I've never heard an explanation for their rationale.
*1989: US 425 is nowhere near US 25.  I assume AR and LA came up with the number, but I've never heard an explanation for their rationale.
*1994: US 400 is nowhere near US... zero?  Apparently AASHTO let KDoT choose from a list of available numbers.
*1994: US 371[ii] is an acceptable number, although it is questionable why this corridor was worthy of a US route designation, since US 71 is a much more direct route between US 371's endpoints.
*2002: US 48[iii] is an acceptable designation.
*2003: US 491 replaced the US 666 designation, and it was the state DOTs who proposed the number.  491 was a reasonable choice in light of the fact that the states involved did not want to duplicate their existing state highway numbers 291 and/or 391.
*2005: US 121[ii] will not connect with US 21; I do not know the story about where this number came from.  But I view this as another "proof" that AASHTO is not methodically assigning 4xx numbers to new routes.

That number was assigned long before 2006. I drove by the Coalfield Expressway Authority office in Pineville, WV, in 2002 and it was adorned with a huge US 121 sign then.

This route really should have been an x19 or an x23. Or even an x52.

I meant to say 2005, that's the year AASHTO approved US 121.  So if you saw signs prior to that, then that suggests VDOT and WVDOT came up with that number themselves.

I feel like 121 should have gone to FL/GA/SC 121.

Yeah, it was proposed earlier. I don't have any sources to cite, but I suspect it was first proposed around 2000 or 2001.

The oddball US-4xx highways were intended to eventually become Interstate corridors.  As such, perhaps their numbers were never intended to be permanent.

↓  See below.  ↓

US 412 is a NHS/ISTEA High Priority Corridor, and was designated in 1982 (see http://www.aaroads.com/high-priority/corr08.html ). It might become a future Interstate.

US 425 was added to the US route system in 1989; this is the preferred corridor for any future extension of I-530 to I-69. Part of US 425 is included in the I-69 corridor (see 6.4 ).

US 400 is also a NHS/ISTEA High Priority Corridor, added to the US system in 1996, the newest US route (see http://www.aaroads.com/high-priority/corr03.html ). The number was picked by Kansas DOT out of a list of available numbers, and agreed to by Missouri and Colorado. US 400 is also planned as a future extension of I-66.

As I've said before, if both AASHTO meetings this year don't approve any new US routes then this decade will be the first one since the US routes were created not to see any new numbers added to the system. Perhaps we should campaign to get the system as proposed by froggie approved, that would see the addition of US 86 and 88 as well as the return of US 28, 32, 38, 66, 94 and 99 (and the relocation of US 96) :sombrero:.

US 121 ends at I-77, which was the original US 21. The number works for me.

This explanation is often given, but some of it just doesn't quite add up.  For example...

US 425 was added to the US route system in 1989; this is the preferred corridor for any future extension of I-530 to I-69. Part of US 425 is included in the I-69 corridor (see 6.4 ).
I'm not sure either I-530 or I-69 were on the radar back in 1989.

US 400 is also a NHS/ISTEA High Priority Corridor, added to the US system in 1996, the newest US route (see http://www.aaroads.com/high-priority/corr03.html ). The number was picked by Kansas DOT out of a list of available numbers, and agreed to by Missouri and Colorado. US 400 is also planned as a future extension of I-66.
I think it would be more accurate to say: US 400 was the bone thrown to Kansas as a consolation after the western I-66 proposal got killed. 
Also, did the list of available numbers (that AASHTO gave to KDoT) include only 4xx numbers?

That’s a good question. I believe Kansas’ rationale was that there was no other Route in the state with the number 400. If that’s the case, then why wasn’t US-400 numbered US-450, which is much more fitting—and available? For that matter, why wasn’t US-350 extended east (even with MO-350 up in Kansas City, US-350 would’ve been concurrent with US-166 and only for a mile, if that).
