US 2

[707]

I'm very confused. I know this may sound stupid, but why is US 2 divided by two seperate segments, but others like US 10 aren't?

Our good friends in Canada have a big piece of their country "in the way."

Actually, one of the US 2's was at one point proposed as US 0, but AASHO decided they didn't like the "0" number on one of their routes. (There's no Route 0 anywhere to my knowledge, at least in this country, and likely this continent.) They settled on a split route, and at some point Canada at least partly signed a continuous route for US 2 on their roads through Ontario and Quebec.

Transcontinental and principal east-west routes were assigned multiples of 10, with the lowest number along the Canadian border (U.S. 2, chosen to avoid a U.S. 0).

Budapest's ring road is M0.  As M is a designation for a freeway, the number is indeed 0.

Is the ferry connection of US 10 considered part of the US route?  If not, then 10 is technically "two segments" (as might be US 9) but still a lot more continuous than US 2 whose two segments have another country in between.

US 10 should be  not considered on the ferry as the Badger is seasonal and only runs one trip a day when it runs. 

The Cape May Ferry does not run after, I believe 9 PM, and in Winter Months when the Jersey and Delaware Shores are dead much earlier.  So, if US 9 was considered on the ferry itself it would be in two segments at night.

This one can have two answers.  It depends on how you look at it, I guess.

Oklahoma has a SH-0 and 0B on paper, but not signed. It could be argued that these are just placeholder designations for highways that don't need actual numbers, of course, but the book does say "0" and "0B", so I'm inclined to just call them that.

Fixed my quote.

The Poteau bypass is officially SH 00.

US 0. A highway that none of us will ever see built.

Is there are theoretical routing of US 2 through Canada to connect the segments?

Looking at Google Maps, a hypothetical route would be I-75 over the International Bridge, ON 550 for a couple of blocks, ON 17, ON 417, a short stretch of PQ Autoroute 40, PQ 201, PQ, 202, PQ 223, and an extremely short stretch of US 11.
