When routes with the same number intersect

[hbelkins]

Happens twice to US 74.

In North Carolina...



In Tennessee...

GA 23 and US 23 have a concurrency for a while. This GSV is in Folkston, the southern end of the concurrency.

The famous "three-legged" junction of QC 132 near Mont-Joli, Quebec.  QC 132 continues straight ahead around the Gaspe Peninsula, then curls back to end at itself here.  This baffled me the first time I saw the intersection, but I figured out what was going on by the time I went that way again two years later.

Another route similar to that is MA 127 (not anymore, but it used to end at itself).

I-90 crosses NY 90 (no confusion because there is no interchange, just an overpass/underpass, and the fact that I-90 is always called the Thruway.).

It could also be argued that US 3 and MA 3 intersect. (Also, are 3 and 3A considered the same number? Nothing was mentioned about letters.)

Virginia checks in with VA 319 everywhere you turn:

VA 376 also does this:

VA 358 does it with shields:

Another route similar to that is MA 127 (not anymore, but it used to end at itself).

If MA 127's no longer a loop through Gloucester & Rockport; where's MA 127's northern terminus?  It's still signed beyond MA 127A's northern terminus.

It could also be argued that US 3 and MA 3 intersect.  (Also, are 3 and 3A considered the same number? Nothing was mentioned about letters.)

One could theoretically say that for every route X that intersects w/route XA or Business Route X.  I could be wrong, but I don't believe the OP's looking for that.

If MA 127's no longer a loop through Gloucester & Rockport; where's MA 127's northern terminus?  It's still signed beyond MA 127A's northern terminus.

It's still mostly a loop. Only the "northernmost" 1 mile was removed. It ends at the rotary with 128 now (it still crosses 128 once before that).

[froggie]

Not mentioned yet is US 27/GA 27 in Lumpkin, GA.

Another route similar to that is MA 127 (not anymore, but it used to end at itself).

If MA 127's no longer a loop through Gloucester & Rockport; where's MA 127's northern terminus?  It's still signed beyond MA 127A's northern terminus.

It's still mostly a loop. Only the "northernmost" 1 mile was removed. It ends at the rotary with 128 now (it still crosses 128 once before that).

The rotary, aka Grant Circle-aka Exit 11, is presently signed as TO 127 in the northbound direction and just simply WASHINGTON ST. for the southbound direction.  Such certainly gives the impression that 127 terminates somewhere north of the rotary.  There's no trailblazer signs supporting such either according to GSV.

Granted, this is OT; what was the reasoning behind the truncation?  If the direction cardinals were confusing for the loop part of 127, MassDOT could've just called it as LOOP 127 and used Inner & Outer Loop notations.

OTOH, MA 127 is fully signed at the MA 128 intersection with Eastern Ave. (Exit 10).

I-283 and PA 283 near Harrisburg. Having worked at both a AAA club in central PA as well as a hotel an exit away from this interchange, I can attest that trying to get much of the non-roadgeek public to understand this junction was an uphill battle.

[hbelkins]

Any interstate-to-state continuance (like the 283s in PA, several NY examples, 440 in Arkansas, etc.) would count.

Virginia's most famous example would be US/VA 360.

[dgolub]

There's an interchange of NY 27 and Nassau CR 27 on Long Island, although the latter is unsigned.

You can go either south, north, or south on CR 4 from this point.

[silverback1065]

In Indiana, I-64 and SR 64 in southern IN. 

[NE2]

Florida renumbered two of these: SR 1 became SR A1A and SR 27 became SR 997.

[cl94]

We could probably count New York's state route extensions of 3DIs at the mutual termini. Depending on where we place the northern terminus of I-787, it and NY 787 may or may not intersect at a mutual terminus.

NY 7 comes pretty darn close to US 7, but the latter is a few miles inside Vermont.

With signed county routes in Warren County, CR 8 intersects NY 8 and CR 9 "bumps" US 9. There are a couple cases in Erie County where an unsigned county route intersects a state route, as well.

[theline]

In Indiana, I-64 and SR 64 in southern IN.

Where do the 64s cross? I'm missing it.

[silverback1065]

Exit 118 on I-64 it's just west og New Albany. It's the sr 62/64 interchange

[robbones]

I 20 & GA 20 east side of Atlanta

[roadman65]

Doesn't US 25 terminate at GA 25 in Brunswick, GA?

I still say QC 132 has the best scenario of all roads.

[theline]

Exit 118 on I-64 it's just west og New Albany. It's the sr 62/64 interchange

Thanks. I didn't realize that SR 64 went that far east. I'm familiar with the western end.

[robbones]

Doesn't US 25 terminate at GA 25 in Brunswick, GA?

Yes it does

[formulanone]

I 20 & GA 20 east side of Atlanta

In Conyers, GA20 is signed north-south, while the interstate is signed east-west.

[Charles2]

In Tuscaloosa County, AL, CR-59 has an interchange with I-20/59.  There aren't any CR-59 shields on I-20/59.

[national highway 1]

In Matador, TX, TX 70 meets US 70.
