urban national parks -signed US routes and interstates?

[FightingIrish]

why does US-10 get two segments, but US-9 does not?

I have no idea. US 10 had only one segment in the 1927 log, so it's not for historical reasons. Perhaps it's because the US 10 ferry is seasonal.

That's right. The SS Badger across Lake Michigan from Manitowoc to Ludington is considered part of US 10.

Otherwise, I do know that US 2 is a segmented route, but it was intended to be that way.

U.S. 1 and U.S. 50 cross the National Mall in the District of Columbia, and are clearly signed.  U.S. 1 North as 14th Street and south as 15th Street, U.S. 50 as  Constitution Avenue, N.W.

Clearly my ass. I don't think any signs remain for US 1 on 15th. (This isn't because it's in a park, however, but because of attrition.)

US 1 and US 50 are very poorly signed in DC, I'd be surprised if anyone can follow their routes without a map!

Agreed.  U.S. 1 Alternate is not signed at all in D.C.  U.S. 29 is also poorly signed. 

But crossing the NPS lands in D.C., the signing is probably O.K.

In the grand scheme, urban or otherwise, I'm pretty sure it comes down to who maintains the road regardless of who owns the land.

I've often wondered how the US routes would be routed inside the park if the routes were signed, and used to try to find ways to give US 14 and US 16 separate endings. (Talk about your useless concurrencies...)

There are too many U.S. routes entering Yellowstone from the east. Either 14 or 16, or both, are superfluous unless you can find a unique route for either of them to exit from the west side of the park. Probably somewhere in the archives of this board are proposed numberings of these through Yellowstone that I'm too lazy to research.

Google Maps signs them through the park, and CHM includes the mileage as well.

If you're talking about Yellowstone, they're wrong.

Unless Google is also wrong about the location of Yellowstone, that's exactly what I'm talking about.  You can always take it up with CHM.

[NE2]

Yep, CHM is wrong. If I cared, I'd care.

The routes that they have the US routes take is from FHWA shapefiles*.

US191 from the west entrance north is signed and officially recognised by AASHTO inside the park, but none of the others are.

The 'unofficial' FHWA shapefile routings are:
US 14: West Thumb (western terminus) - Lake Village - East Entrance
US 16: West Thumb (western terminus) - Lake Village - East Entrance
US 20: West Entrance - Madison - Norris - Canyon Village - Lake Village - East Entrance
US 89: South Entrance - West Thumb - Old Faithful - Madison - Norris - Mammoth - North Entrance
US 191: South Entrance - West Thumb - Old Faithful - Madison - West Entrance
US 212: Tower Jct (western terminus) - Northeast Entrance
US 287: South Entrance - West Thumb - Old Faithful - Madison - West Entrance

*That there isn't a Yellowstone-sized gap on CHM is a consensus position dating from July 2008 and those shape files. It is a bit of an inconsistency as routes have to be signed or official (official-only with many caveats - Interstates and E roads only) and these routings are neither. This status quo may change.

[vdeane]

I'd go with the shapefiles.  Having a gap is silly.  Plus if CHM deleted everything that wasn't signed, they'd have to drop all non-freeways in DC!

[corco]

When I drove the entire Wyoming state highway system, I omitted the routes within the park except for the part of 191 in Montana. There's no signage within the park and the AASHTO doesn't acknowledge them, so I don't know how you consider them to be routes.

Who or what is CHM?

I think this has been asked somewhere but I don't recall the outcome or where it came up - assuming route continuity, is there anywhere else where the US Highway system requires a park entry fee? I don't believe there is, in which case it makes sense why these are not officially routes.

[corco]

To my knowledge no- heck, even just south of Yellowstone through Teton there is no entry fee and the routes are signed (which also lends to me thinking that the routes are not routes through Yellowstone, since the other national park in the same state immediately adjacent to the park in question has totally different practices).

16A in South Dakota goes through a national park, and you are directed towards an entry fee, but there is a sign to this effect (pardon blurriness)


that reads "Non Stop Through Traffic on 16A Exempt"

Trail Ridge Road (US 34) through Rocky Mountain NP?

Yes, according to Rocky Mountain NP.  The roads are marked as US-34 and US-36 on the map as well.
