Highways you're surprised it hasn't gotten truncated/decommissioned

US 10, especially in Michigan.  Just run M-10 to "The Beaver" and call it good.

You realize that M-10 and US-10 are over 80 miles apart, right?

[webny99]

US 11 and its splits. Everything north south of Watertown, NY, is pretty much parallel to an interstate.

FTFY.

I have the opposite take that US 10 still should end in Detroit.  If anything US 24 ending at the Lodge Freeway would be just as an appropriate terminus. 

[kphoger]

US-400 west of Dodge City.

I mean, seriously, who are they kidding?

[CNGL-Leudimin]

I-894. Again, why is still around? It made sense back in the day, but now it is totally redundant to I-41.

US 19W as redundant to I-26. Change US 19E to "plain" US 19.

Yeah, I had two different thoughts going and they got jumbled as fingers hit keyboard. I was torn between "everything south of Watertown" and "everything but the portion north of Watertown" and it came out wrong.

While I'm at it, all of US 25 north of Corbin.

I've heard that so many times but never actually seen a "standard"  for US Routes.  Allegedly that's what happened with US 89 and it's alternate route through the mining community of Jerome. 

I don't know about construction standards, but there are supposed to be utility standards for US routes. They're supposed to be on major interregional corridors. That exempts a whole lot of mileage in Kentucky, including all of US 431, most if not all of US 421, and US 460 west of Pikeville. No one in Paintsville or Prestonsburg is going to take 460 to Frankfort, nor will they take US 431 from Owensboro to Nashville.

MD-3 Business in Glen Burnie. It no longer connects with mainline MD-3 because I-97 replaced it in the area.

Going back to Indiana, while I'm not surprised it hasn't been truncated or decommissioned, there's no real need for US 421 north of Greensburg. The highway heading north from Greensburg to Michigan City all follow routes that are occupied by either interstates (I-74) or various state highways. Parts of SR 29, SR 39 and SR 43 could very easily assume parts of US 421 and INDOT would lose no control of the highway. I'm guessing for some reason there's a need for a single highway connecting Indy to Michigan City.

As for US 35, in reality it's the state highway that can go from Kokomo to I-69, there's no need for SR 22. US 35 should only share a multiplex with I-69 and a part of SR 28 in Delaware County. It serves decent for a Kokomo to Michigan City highway.

And then there's my more recent belief that parts of SR 67 should be decommissioned from Indianapolis to Daleville due to the state highway sharing its route with one other highway in between those two communities (I-465, US 36, SR 9, I-69)

[Roadgeekteen]

MA 4 or MA 225 in Lexington.

[ztonyg]

US 35 doesn't really need to be a US highway north of Kokomo and could be truncated, though the truncated part should be state highways.

Again, what's the point?  Why truncate the US route if the truncated part is still going to be a state route?

Tell that to Arizona with AZ 89 and AZ 89A.

For some reason Arizona didn't want to sign US 89 along I-40. Why? I don't know.

[STLmapboy]

MO-265. All concurrencies save a shor 3 mile section.

[ozarkman417]

MO-265. All concurrencies save a shor 3 mile section.

MO 413 has a similar case. Its time in Springfield and a short section near Billings are the only two places were it does not have a concurrency. You could truncate 265 so it starts near Silver Dollar City and it ends at US 65.

MO 165 is entirely concurrent with County 165 and was somewhat recently truncated near Holister.

As if a couple reassurance shields saved them that much money and yet they didn't relinquish anything.

[US 89]

I’m surprised Arizona hasn’t dumped US 60 west of Phoenix given their track record with routes like US 89. The part east of Wickenburg could easily become a US 93 extension, with the remaining segments becoming either SR 60 or returned to county maintenance (as happened with 66 further north).

[sparker]

US 199 is definitely one, especially since its parent doesn't exist anymore.

US 199.  Sure it crosses a state line, but still?
US 10, especially in Michigan.  Just run M-10 to "The Beaver" and call it good.

US 199 at least was embroiled in the Winnemucca to the Sea saga for awhile.  US 199 is one of those highways that doesn't really have apparent regional importance until you end up driving it. 

US 199 functions as the only reasonable tether from the coast to inland southern Oregon and northern California from the Klamath River to the Rogue River.  As a bi-state route, the criteria for existence as a US route is settled; "demoting" it to two state highways would be both gratuitous and petty.  Renumbering as part of the revisitation of the Winnemucca-to-the-Sea concept would be the only arguable reason for changing its current designation -- but that's a fictional subject.  But in the general vicinity, routes that to me seem to have the Damoclean sword hanging over their existence would be CA 3 east of I-5 to Montague, OR 70 (there's gotta be something political going on there!), and the northern section of CA 169 (it's pretty much a neighborhood street along the river). 

[Max Rockatansky]

Some others from California that I've found odd:

-  CA 229; much of the highway is a single lane and the two lane portion is part of former US 466.  CA 229 is doesn't really serve a greater transportation purpose nor connects to a state facility.  The highway essentially is a local road that is overbuilt for state standards. 
-  CA 172; much as the and same as CA 229 with a large one lane section.  This route is former CA 36 over Mineral Summit, the modern road is infinitely superior.  The only people that live on CA 172 are at the East terminus and the rest of the highway is closed during winters. 

[GaryV]

While I'm at it, all of US 25 north of Corbin.

I agree - and also all of US-25 W.  But wouldn't it just get renumbered as a Kentucky route?

[roadman65]

I am surprised that US 9 was not recommissioned in NY, being that state truncated US 15 when the NY 17 freeway was constructed west of Corning.

North of Albany it is completely surpassed by I-87. Maybe from NYC to Albany not so much as it has no freeway directly near it.

Any of the remaining spurs in Michigan that serve state parks (M-211 and M-212 come to mind)

US 5 would be gone if the New England states were like California.

Speaking of US 5, CT 15 north of Meriden.  Granted, most people refer to the Berlin Turnpike and the South Hartford expressway as Route 15, but with the exception of the last half mile or so between Main St and I-84, it is concurrent with US 5. 

And then there's US 202.  What is a child route of a road in Maine doing in Delaware?  You can eliminate it by expanding US 301 and rerouting it onto US 13 north of Wilmington to Morrisville, PA (via a brief concurrency with DE 1), then using US 13 for US 202 up to Haverstraw, NY (you'd need to eliminate the 1/2 mile NJ 13, and yes you'd be breaking a US/state route rule in NY, but NY 13 is far enough away).   In NY, all you'd need to do is extend NY 116 and NY 100 briefly.  In CT, extend CT 53 to Brookfield and re-extend CT 25 to Canton.  In MA, just create a new state route from Westfield to Belchetown, then extend MA 21 north of there and you can even use NH 21 to Concord (would work great with my proposed CT/MA 21).    Other than extending NH 43, you're pretty much done. 

And no one has mentioned MA 128 yet? <ducks and runs for cover>

And with that - I'll add MA 128. Should not exist south / west of the I-95 interchange in Peabody

See I've always been cool with that.  At least it's a state facility reaching another state facility.

na I love MA 128.
