Interesting things about specific US route terminuses

[hbelkins]

US 6 ends in Provincetown, MA on Federal land.  Are there any other US routes that end that way?

US 14 and US 16 end at the entrance to Yellowstone National Park.

US 14 and US 16 end at the entrance to Yellowstone National Park.

US 385 at Big Bend National Park.

US 209 ends at PA 147 in Millersburg--instead of ending at a US route, Interstate, or seaboard, it terminates at a lowly state route.

[US 89]

US 14 and US 16 end at the entrance to Yellowstone National Park.

As does US 212, but at a different entrance

US 180 as mentioned up thread does as well with Grand Canyon National Park.

US 209 used to run down to US 22/322, I wonder why that was changed

Prior to the 1964 renumbering, no fewer than 8 US highways terminated at US 101 in CA (40,50,60,70,80,199,299,399); that was cut back to just US 199 after that year.  In addition -- again, prior to '64, all the fully cross-country US highways ending in "0" terminated at US 101 (adding US 20 and US 30 in OR).  And keeping in the pre-renumbering "101" family -- Alternate US 101 was the western terminus (1935-64) of US 66, and hosted the truly weirdest set of termini, that of US 6 and US 91, which terminated not at Alternate 101 but along that route, terminating at each other -- from opposite directions -- and the junction of SSR 15, which terminated there as well in Long Beach.

When US 15 was moved to the east bank of the Susquehanna, US 209 was dropped south of Millersburg and replaced by US 15. However, US 15 moved back to the west bank, with PA 147 replacing it.

US 62 is the only east-west US route to go from the Mexican Border to the Canadian Border (El Paso, TX to Niagara Falls, NY)

[mrcmc888]

US 69 and 96 end at each other in Port Arthur, Texas.  US 96's north end is also at what will become Interstate 69.

US-258 ends at what was the front gate of Fort Monroe. Now most of the land is owned by the City of Hampton, with only a smaller interior portion used as a national monument.
US-64 and US-158 both end at the entrance to the Cape Hatteras National Seashore.

US-64 and US-158 both end at the entrance to the Cape Hatteras National Seashore.

US 264 used to end there too, as it was concurrent with US 64.

[sbeaver44]

Both segments of US 422 have a Western end at US 322.

[Hwy 61 Revisited]

Both segments of US 422 have a Western end at US 322.

Also, US 422 never directly touches US 22--it stops short at US 119.

the eastern end of US 76 is 1.7 miles long

The eastern terminus of US 466 in Kingman was the only place it touched US 66 as they didn't meet in Barstow.  Also the eastern terminus was somewhat well known for being co-signed with US 93 but US 466 was there first and was the first US Route to cross the Hoover Dam.

US 399 had an odd north terminus which multiplexed US 99 north into downtown Bakersfield to US 466.

Back when US 6 ran to Long Beach, it ended going the wrong way at both termini. It still does so at its Eastern end (going physically West).

US 30's ends haven't moved much ever since the US Route system was created. They have always been in Astoria OR (where the Columbia river enters the Pacific) and Atlantic City NJ (logically on the Atlantic shore) respectively, making it the only US Route that has always run coast to coast.

US 52 is the only east-west US highway that officially ends at the Canadian border.  3 of the 4 US 2's ends are near the border and US 62 ends at NY 104, less than 1 mile from the border.

Speaking of US 62, I know someone mentioned it earlier, but it's the only east-west US highway that ends at the Mexican border.

US 81 is not only concurrent with I-29 throughout most of North Dakota, but they're also co-signed all the way to the Canadian border. I'm just surprised about that considering the fact that they rarely sign US 52 on I-94 and they truncated US 10 to Fargo. That, and the fact that it's southern end was truncated to I-35W/US 287.

US 285 ends in Sanderson, TX, the name of the person probably most interested in the endpoint.  The other end is right where he lives.

The northern end of US 220 is at the NY/PA state line. Until it was truncated a few years ago, it ended just inside New York at a local street that is old NY 17.

Interestingly, one of the other state line termini also involves New York. US 46 ends at the NJ/NY state line in the middle of the George Washington Bridge.

US 46 also ends at a state route, NJ 94, which is usually frowned-upon. It used to extend into PA along the Portland-Columbia Toll Bridge, but then US 611 was moved into New Jersey, truncating it.

[Max Rockatansky]

US 223 multiplexes US 23 just over the State Line into Ohio which maintains its interstate Route status. 

[bugo]

US 259 ends at US 59 at each end.

[jemacedo9]

PA has a few, some of which are mentioned above:

US 209 ends at a state route, PA 147 (mentioned above)
US 220 ends at the state line (mentioned above), but also never touches it's parent
US 206 never touches it's parent (at one time there was an implied multiplex of US 206 and US 209)
US 222 never touches it's parent
US 422 never touches it's parent (mentioned above) and both segments have a western terminus at the same route (US 322)

[Eth]

US 25 ends at a route of the same number (GA 25), and does so while concurrent with another route of the same number (GA 25 Connector). And yes, they're all signed.
