Post by: Voyager on March 29, 2009, 05:11:08 AM

Presently, US 20; historically, US 6.

How about the longest north-south (historically and currently)?

How about in the "no longer existing category"?

LOL master son, but seriously, I'd like to know the longest decomissioned north-south/south-north U.S. route.

Anticipating a possible future question:

281 is the longest 3 digit US route.

Hmm...how about the longest decomissioned 3-digit route?

Looks like 666 is the winner.

Presently, US 20; historically, US 6.

Since there's a gap in US-20 in Yellowstone Park, US-6 is still the longest continuous route. :coffee:

OK, now how about the longest diagonal US highway (NE-SW or SE to NW)? 

US 52  NW-SE 
US 62  SW to NE?

Or did i forget one?

Does US 11 count as a diagonal?

New Orleans (SW) to Rouses Point, NY (NE)

I does spend significant parts of its route going east-west including through my hometown of Bloomsburg, PA.

According to C-DOT, US-6 now ends in Mack, CO -- 12 miles from the UT Border, but we all know better. :sombrero:  Last week, I saw the "END 6" sign they must have put up sometime in the last year -- I have yet to see it on any street-view website.  I'll be back out there next week, with camera in hand for proof.

But then again C-DOT has pretty much abused US-6 for years. :pan: This is just another layer of icing on the cake.

I'd have guessed US 30.
