Unauthorized routes

[roadman65]

I couldn't help notice that US 1 & 90 Alternate designations in Jacksonville, Florida were not approved as such despite it's signing at the time.  Both were to have business routes and mainlines were to be signed on alternate routes.  It's all in the 1968 archives at AASHTO.

What other routes will I find never approved but signed in the field?

CA 130 east of Mount Hamilton is signed by Santa Clara County to the Merced County Line.  That segment of San Antonio Valley Road and Del Puerto Canyon Road were never State Highways.

[NWI_Irish96]

Business US Routes are not on the books in Indiana but signed by several cities.

MA 2A was recently extended into Boston, but only by signage, not officially.

At one point VA 407 had some postings west of its west end. Not sure if they’re still there.

IIRC the north part of US 377 was never approved by AASHTO but OKDOT went ahead and extended the designation along OK 99.

Per the Michigan Highways site http://michiganhighways.org/listings/M-013.html

What is now M-13 north of Bay City was signed ALT US-23, and had to be changed when [then] AASHO denied it.

Wasn't I-90 posted on the Chicago Skyway at one time when it actually wasn't really I-90?

According to IDOT and FHWA, it is I-90.  Its only the City of Chicago that seems to think it isn't.

IIRC the north part of US 377 was never approved by AASHTO but OKDOT went ahead and extended the designation along OK 99.

It was apparently written into law by Congress.

Ah.  Was the route being legislated north to I-44 something that occurred after it was first signed?

US 136 East of Veedersburg IN is technically unauthorized. AFAIK it was officially truncated, but Indiana never removed the signs.

In Michigan, I-275 is signed as concurrent with I-96 between the I-96/I-275/M-14 and I-96/I-696/M-5 junctions, but according to FHWA I-275 ends at I-96/M-14.

Keep going...AASHO eventually approved them.

No. According to the AASHTO document archive, the full details of what happened is this: There was a Highway 99 Association (SH-99 is the Oklahoma SH designation for the corridor, that is still concurrent with US-377, "just in case", I guess?) that lobbied ODOT (and its predecessor Oklahoma Department of Highways) to request a US route designation for SH-99. ODOT obliged. At the time, AASHTO worked on a point-scoring method that would only approve a designation if it scored highly enough according to a formula they used. SH-99 scored poorly, primarily because of its proximity to the already-existing US-177. ODOT tried a number of different route extensions (besides just US-377) and reroutes to try to get a US shield for the highway, but AASHTO wouldn't play ball.

The Highway 99 Association saw that they were getting nowhere going through ODOT, so they turned to Rep. Wes Watkins (both-OK), who added the designation to a bigger transportation bill. It was signed by President Reagan. ODOT then submitted one last application to AASHTO asking them to approve the US-377 designation according to what was now federal law. They still declined it. ODOT, caught between obeying either AASHTO or Congress, threw their lot in with Congress and posted the signs according to the law.

US 26 was pulled off of ORH 47 [SW Market and Clay Streets] and 91 (former? OR 99W) [SW Naito Pkwy] through downtown Portland and onto ORH 61 (I-405), SW Broadway, 5th Ave, Sheridan St, 3rd Ave, and Arthur St, and so far as I can tell, never told AASHTO about it.

Wasn't US 98 signed west of it's western terminus?

[Mapmikey]

Wasn't US 98 signed west of it's western terminus?

Which western terminus?

There have been US 98 postings left over from its Natchez truncation (official terminus then was the Mississippi River Br).

BTW Louisiana tried 3 times to get US 98 extended to Monroe.  AASHO consented on the 3rd try but said it had to be US 265 for some reason.

[fillup420]

the under-construction I-885 in Durham NC hasn't been approved by AASHTO, but signs are going up currently

[jmacswimmer]

The Baltimore Beltway is technically MD 695 from the northeast I-95 interchange, over the Key Bridge to the I-97 interchange, but is signed as I-695 along with the rest of the Beltway.

[Avalanchez71]

How about both TRUCK US 31 and TRUCK US 431 in Franklin, TN?  There are signs everywhere denoting truck routes all over town.  The "main" TRUCK US 31 runs along SR 397 from SR 6 to SR 6, however, there is another one that is barley signed along Downs Blvd with one sign.  It appears to run without signage along SR 96 to US 431 along TRUCK US 431 back over to US 31.  Then the same type of thing is haywire with TRUCK US 431.  There is even signage nearly showing that the mainline and truck route are concurrent when the truck route should end.

Wasn't US 98 signed west of it's western terminus?

Yes, it was still signed to the river even after its truncation to Bude because at the time MDOT did about as well with signage as some Tennessee cities.
