State routes of SAME NUMBER intersecting

[Alps]

There can only possibly be a handful of these around the country. What I just discovered: The western terminus of WV 7 is mere feet from OH 7. For all intents and purposes, they intersect, despite being different roads. So, yeah, where else does this possibly happen?

There's the US-95 in California/Arizona 95 mess and the US-89 in Idaho/Wyoming 89 mess, but in terms of just state highways I can't think of anything.

I-295 and D.C. 295 in Southeast Washington would seem to qualify, though neither are state routes (since D.C. is not a state and I-295 is not a state route either).

Not exactly the same number, but OR-39 intersects with CA-161 and CA-139 at the CA/OR border.

[KEVIN_224]

Are we counting the route number staying the same at the state line, such as CT Route 8 becoming MA 8 and eventually VT Route 8?

[jp the roadgeek]

Just about every state numbered route in New England that crosses a state boundary and retains state maintenance.  Also reciprocal in most cases with NY as well, the only exceptions being VT 9/ NY 7, and those roads that become NY county routes.  If you mean two unrelated roads with the same number (almost ) intersecting, then NH 113 and ME 113 intersect US 302 about 3 miles apart in Conway, NH and Fryeburg, ME.

Connecticut Route 145 had a three-way intersection (i.e. with itself) for a few decades starting in 1932. I'd love to see how that was signed.

[corco]

Washington 100 has a three way intersection with itself- it's unsigned.

[NE2]

I seem to remember a T intersection on the state line of two same-numbered routes. Can't think of where, however.

[formulanone]

It's probably rare enough where two same-numbered, yet different classifications of roads intersect.

Hwy 548 intersects itself at a T intersection on St. Joseph's Island east of Sault Ste. Marie.

QC 132 does a big loop around the Gaspesie and then ends at itself near Mont-Joli.

But that's the same route, not two routes with the same number.

[bugo]

OK 63A has 3 ends,  OK 77S has 4.  That means the routes intersect themselves.

[cpzilliacus]

There are plenty of state highways that retain their state number in the next state. 

I can name several of those.

I assumed those didn't count for this thread because the OP referred to situations involving "different roads."

[deathtopumpkins]

They don't quite intersect, nor are they both state routes, but NH 4 in Dover is only a few miles from US 4 in Durham.

I've never understood why NH numbered this road route 4. Sure, it does connect to Maine's route 4, but it's hardly a direct through route, especially considering the ME 236 multiplex right across the border and the fact that it begins, barely signed, on a side street in Dover.

OK 63A has 3 ends,  OK 77S has 4.  That means the routes intersect themselves.

OK 77D has 3 ends as well.

If you include the ferries:
-NY 373 becomes a city street in Burlington, VT
-NY 314 ends at a T intersection with VT 314

IL-172 used to be a 'T' shaped route with a leg to Prophetstown.  I was cut back to an 'L' sometime in the 1970s.

I vaguely recall that when Interstate 88 was new in Illinois, it intersected Illinois Route 88 in Rock Falls.  This was before they renamed it Illinois Route 40.  Did they simultaneously exist?  I seem to recall seeing an IL 88 sign while on I-88.

[SteveG1988]

What about NJ440-NY440-NJ440, would that count, using two seperate bridges to link staten island to NJ.

There has been discussion elsewhere about VDOT's practice of assigning one route number to an assortment of state-maintained roads and streets on several of its college and university campuses (which obviously intersect each other), including these:

Va. 302 - University of Virginia
Va. 303 - VMI
Va. 314 - Virginia Tech

See the excellent Virginia Highways Project for more.  Especially on this page.

Yes, they simultaneously existed when I-88(west) was designated in the late 1980s until IL88 was changed to IL40 in the early 1990s

While it is true Virginia has plenty of these, most are not posted well enough to qualify...

Right off the top of my head, the only ones I know are posted in all directions at some intersections are VA 319, VA 358, and VA 376.

From 1933 to 1966, Virginia had a regular state highway that looped onto itself.  I don't know how it was posted, but here is a mapscan showing it.  Even weirder is that in 1966, VA 169 was extended north and the loop remained in the primary system.  I have not found a county map that shows what the loop became numbered as (169Y?):
