Overlaps in Connecticut US Routes

[kurumi]

This is super trivial, but looking at intersections of US routes within the state:

US 1 and US 1 do not overlap any routes (makes sense, as a shoreline route)

Among US 5, 6, 7, 44, 202, there are 10 potential interactions (5 * 4 / 2). (Although 7 and 202 intersect a few times, as do 6 and 44.)

Two pairs of routes do not intersect (5/7 and 5/202) in-state; but 8 other pairs do.

7 of the 8 involve overlaps (aka multiplexes). The other one (US 5 and US 6) was also an overlap back when US 6 crossed the Charter Oak Bridge; currently US 6 is not signed where it crosses US 5.

A simple 4-way intersection where two US routes cross? None exist in Connecticut.

I feel simple 4-way intersections of US routes is not a hallmark of the US route system in any state.

Do expressway interchanges count?  If so, then there's US 1 and US 7 in Norwalk.

6 and 202 overlap from NY State into Danbury.

Feels like this one would be continuous overlap...🙃

Derp. Meant to type US 1A (but for one of them, not both :-)

Thinking of NJ, 206 is on 80 where it crosses 46, 40/322 crosses 9 at grade, as does 30.

I take it that the end of a concurrency ending at a simple 3-way (US5/44 × 2) or 4-way surface intersection (eastern US44/202) won't do?

Agreed.  In NY all I can think of offhand are 11/20 and 20/62.  With less strict criteria (i.e. where two US routes intersect without a terminus or concurrency) you could add 20A/219 and 9/44.

New Hampshire:

US 3 N/S and US 302 E/W intersect in Twin Mountain. 

NH 10 used to be signed on US 302 up to Twin Mountain, terminating there (northern terminus) but is no longer signed past Littleton).  I have no idea why, as NH 10 should have its northern terminus in Woodsville NH.  No reason to extend the concurrency with US 302 to Littleton.

I believe it does end at US 302 in Woodsville, yet for some reason is still signed all the way to Littleton.

Historically, US 1 and US 5 did (and still should; hate how US 5 ends abruptly right in the middle of State St).

5 and 202 in Holyoke, MA.
5 and 20 have a expressway/circle in West Springfield (so, close?)

Well, it ends at an interchange with I-91, but agreed that there's no good reason for it not to continue down State Street to US 1 in New Haven.

Well, the reason is that that section of State Street is not part of the state highway system, and Connecticut is not fond of signing routes on roads they don't maintain.

^ Given their quantity of unsigned routes, seems ConnDOT isn't fond of signing routes even on roads they DO maintain...
