US 199

[Bickendan]

Thou shalt not kill (the remnants of US 66 or 99).

Also, why keep US 400 when US 166 pretty much runs the same way?

FTFY

The explanation, as near as I can tell, is that US 199 was never formally moved off the 6th/7th couplet; in fact, this is still the formally defined routing of the Redwood Highway.  This might explain why US 199 is signed (along with OR 99) along 6th & 7th Streets in Grants Pass:

 

The Grants Pass Parkway, which most of the signage indicates is the actual route of US 199 (and has since the facility opened in about 1990), is considered by ODOT to be a spur of US 199.

Now, though, it looks like it will formally be moved onto the Grants Pass Parkway.  I wonder if that will immediately end the signed duplex on 6th/7th, which I kind of enjoyed.

I just returned from a trip to the redwoods, and I can now answer my own question: ODOT has now removed the US 199 shields from 6th/7th.  Here's the same assembly pictured above as it appears now:

Also, if US 166 is only regionally important, why not just downgrade it to KS 166? Also, why keep US 166 when US 400 pretty much runs the same way?

Why bother to replace all the signs?

Also US 400 has only been around since the 80s or so. US 166 is original to the system.

US 400 is an illegitimate child route, it should really be a new US 450 with a western end at US 50 in Garden City KS. An easy method is to white out the first zero and stick a 5 on.
Or you could reroute US 166 onto US 400.
US 412 should be a minor violation of the grid like US 59, a US 86 with a western terminus at US 56 at Guymon OK.
US 425 should be US 265 ending at US 65 at Clayton. US 65 should be re-extended back to Natchez.
But I do agree US 266 should go.

U.S. 400 could have been a resurrection of U.S. 154, since it's a very marginally compliant U.S route, what with its last furlong being in Missouri. (If you disregard the AASHTO directive that U.S. routes should not be extended over another merely to reach a terminus with another U.S. or interstate route). I find its westward extension over U.S. 50 into Colorado as far as the junction with U.S. 385 to be ridiculous. Colorado barely acknowledges the appearance/disappearance of 400 at that junction. But, another possibility would have been to extend Colorado's short U.S. 350 over 50 from La Junta to Dodge City, as long as you could accept a silly concurrency of over 200 miles.

U.S. 412 isn't a minor violation of the grid. It should have been x64 or a child of some other appropriate intersecting route, and never extended west of Boise City. (See rule above). Admittedly, it didn't go that far west when first established, so a non-systematic number may have seemed more appropriate when it was first established. Same with U.S. 425, and I agree about U.S. 65 being a more appropriate route to extend.

Too bad Oklahoma has already used 266 as a state route, so U.S. 266 would have to get a different state route number such as 264 upon its decommissioning.

I can grudgingly accept 400 since that number implies it is a spur of '00', or a spur of nothing as '00' isn't a valid route number in the US (internally-designated OK-0 and 0B notwithstanding). 412 is a worse violation since it implies it is a spur of 12, which it never even comes close to.

Also don't underestimate Oklahoma's willingness to do awful things to its numbering system; we already have two of a bunch of different highways (SH-74, SH-4, SH-37, three SH-9As, et al) so it's not like Oklahoma having two SH-266s is really going to cause the entire system to cave in–though it would be uncomfortably close to existing 266, it's not like it'll be any worse than US-270/OK-270.

I can see you've driven across Kansas too. And listened to its politicians of late.EDIT: Drifting way off thread and into verboten topics. Sorry.
