Can't follow the through route

[Alps]

I'm not talking about route discontinuities. I'm talking about being on a continuous route that you cannot follow for whatever reason. Isolated examples have come up in different threads, but I don't think we've ever had a catch-all.

* US 61 in Turrel, AR (the most recent) - cannot jump onto I-55 heading SB, missing ramp
* US 85/87, I forget where, mysteriously begins and ends without any I-25 interchange
* Long ago, someone mentioned a no-left-turn prohibition that took out the through route.

For a couple of years, it seemed that NJ 29 had an issue where one block of it was one-way SB only, but NJ 29 NB still officially went that way. I know there are scattered county routes where this happens as well, not necessarily in NJ (though Hudson County has a number of one-way county routes, so it might).

It appears VA 131 has a situation like NJ 29. http://www.vahighways.com/route-log/va121-140.htm#va131

Currently, you cannot get to SB IL-129 from SB I-55 at Exit 238 in Wilmington, Illinois.  The ramp and bridge were removed this past summer.  IDOT also removed the U-turn ramp there making the other movement, NB IL-129 to SB I-55 impossible without using the next interchange.

US-10 between Manitowoc, WI and Ludington, MI for most of the year. Whether US-10 in Michigan should be downgraded to a state highway is another topic.

That's just an interchange with missing movements, not a case where you can't follow a through route.

However, it is also the beginning/ending point for IL-129, thus, the movements are missing to continue onto a through route.

A bike route in Frisco.

Not very well known, but there is a very short segment of CT 10 in Hamden where you cannot follow the through route southbound.  The road splits into 2 1-way segments around 2 gas stations and a Popeye's.  The northbound segment is designated as CT 10, but the southbound segment is SR 706.  They come back together in less than 1000 ft.

More than once, the District of Columbia has denied left turns at intersections where one of the U.S. routes passing through D.C. is supposed to make that left.

Several times on U.S. 29, and at least once on U.S. 1.  Not sure if it has happened on U.S. 50 or not.

The No Left Turn signs have been removed when the error was pointed out.

Sounds like the same is true with US 61. According to Teh Googles, you have to travel up US 63 to the first available exit and then double back.

* US 85/87, I forget where, mysteriously begins and ends without any I-25 interchange

This is north of Fountain, south of Colorado Springs CO. The road carrying U.S. 85-87 crosses I-25 and the routes (northbound) join I-25 there, but there is no interchange. In eastern Colorado, U.S. 24 parallels I-70 and similarly, invisibly, westbound jumps onto the interstate. Same stretch of U.S. 24 going east out of Burlington just ends, and the road becomes the undesignated I-70 frontage road toward Kansas.

US 377 south in Fort Worth. The sign says to follow US 377 with US 287 and I-35W going back north but there's nothing posted after that. You'd have to get on Pharr St. and get back on 35W SB.

While it is technically possible to follow the through routes through Syracuse and Plattsburg, the signage there is so bad that you're sure to get lost along the way unless you carefully plan everything.  In Plattsburg, the signage even lies around the NY 3/US 9 intersection.

In Vermont, you have US 7A which only exists southbound.

You can certainly follow it; it's just not signed.

This situation also prevents one from following US 33 EB leaving US 250 right before it transitions to VA 33 in Richmond.

Well isn't that the same thing as the OP's US 61 example?  Both highways "end" with no ramp to the rest of the route and no signage to show you how to get to the route?

No, because US 61 has no ramp. Period. You have to go up US 63 to the first interchange and U-turn.

How about NB MD 528 in Ocean City, MD on Philadelphia Avenue?  Where the one way pair of streets are Baltimore Avenue (NB) and Philadelphia Avenue (SB) MD 528 is only assigned on Philadelphia while its counterpart has another unsigned MD Route 378.

However, with MD 378 signed or unsigned, you have that to at least make the connection.  It may count as one as a very unusual situation as normally both streets of a one way pair have the same number.  It is odd that MDSHA would give another route number instead of letting them both be MD 528.

Then again you cannot travel MD 528 NB a few blocks from US 50 northward, so I guess you can count it from that point of view as legislatively MD 528 is only on Philadelphia Avenue a one way street.

Teh Googles isn't worth a damn.  That is how you would have to go (driving 2.6 miles out of your way) if you wanted to follow US 61, but I highly doubt that any portion of that route is actually designated as part of US 61, and Street View confirms that it's not signed as such.

The other huge difference between this and the IL 129 example is that, while it may be awkward to end at a glorified RIRO, it doesn't stop you from following IL 129 because once you've reached the interchange, you're done.  Here, you can't follow US 61 (or AR 77 for that matter) without doubling back for two and a half miles.

Other Maryland examples:

US 1 in Baltimore City - south of North Ave, US 1 is routed southbound on Monroe and northbound on Fulton. Nevermind the fact that Fulton Ave is two way at this point. So if you are on southbound Fulton, you are not on the route.
MD 7 in Elkton - part of East Main Street is eastbound only. Therefore, if you are traveling westbound from the route's beginning near the DE line, there is a break in the route.
MD 139- traveling northbound, there is a break in the route where you must drive on Charlcote Rd before turning left to stay on the route. This is because of some two-way one-way two-way one-way weirdness on Charles Street.

Burlington County NJ has a county route that was cut off due to 9/11, and a state route terminus was cut off due to the same reason.

New Jersey Route 68 ends at General Circle on Joint Base Dix-McGuire-Lakehurst, along with CR 616

County Route 545, the section through the Fort Dix side of the base has long been closed to through traffic. Traffic is detoured through an upgraded road called Range Road that formed the back route to Wrightstown NJ, and was upgraded to handle the traffic that is forced to use it through a repaving and regrading of the shoulders. This road services the ranges setup in the woods around the area.

Technicaly Us9 in NJ cannot be followed through, due to the Beesleys Point Bridge being closed, and the parkway serving as Temporary US9.

[roadman65]

If you follow the trail blazing for US 206 in Lawrenceville, NJ you will not be following the through route. At the point where US 206 turns south on Princeton Avenue, there is a sign missing where US 206 SB changes alignment.  If you continue on the main road ahead, that is only NB US 206 but a two way road, you will end up at the Brunswick Circle where there is another US 206 shield directing SB US 206 back to itself via Strawberry Street.   

Nonetheless, you are leaving the mainline unless you know the actual alignment and make the turn where the sign is lacking.

Found another one I sorta knew about - NJ 88 eastbound, you are forced straight onto a county route at NJ 70 at a five-way intersection, and have to turn left/right to continue on legislated 88.

This is 88 eastbound according to the SLD.

Yeah, it's a strange case because if you're heading east on 70, the bear right onto what has always been 88 is indeed signed as East 88. You can see that as you drive straight on 88 EB but can't turn to follow the sign.
