US or Interstate highways that leave a state and then come back

[ranger5830]

Hi all,

I was planning a summer road trip and noticed that US 212 goes from South Dakota to Wyoming to Montana then back to Wyoming after about 300 miles in Montana.  Are there other examples of this?  The only other one I can think of is US 395 leaves southern California to go into Nevada for about 85 miles then goes into Northern CA.  Are there any others?

2 and 141 alternate between Michigan and Wisconsin. 

52 loops into Kentucky for several blocks.

US-5 once briefly looped into NH.

more can be found here...

There's US 191 north of West Yellowstone (MT-WY-MT). It's only about 5-6 miles, though.
If your trip comes through the Black Hills, you should check out Spearfish Canyon.

US 62 leaves and reenters Texas after a good distance.

I-24 dips into Georgia and back into Tennessee but it is brief.

[codyg1985]

US 72 leaves west Tennessee around Piperton (east of Memphis) and then reappears far to the east at South Pittsburg, TN (west of Chattanooga).

[Takumi]

US 340 in Virginia. I think this has been discussed before.

[Doctor Whom]

US 50 goes from MD to DC to VA to WV to MD to WV.

[US81]

US 62 leaves and reenters Texas after a good distance...

as does US 54 and US 180.

NJ/NY 440 is a state route that does this (and not just briefly either. And there are toll river crossings involved both times). Also I-86 crosses the PA/NY state line several times.

Also I-86 crosses the PA/NY state line several times.

The interesting thing about this section (near Sayre, PA) is that it was constructed and is maintained by NYSDOT, and the NY mileposts and exit numbers are maintained. The only indication that you've re-entered PA is a small "STATE BORDER"  sign. After a NY interchange that is entirely in PA, I-86 goes back into NY about a mile to the east.

I-684: Mostly New York, but into Connecticut.

I thought about 180 (as it runs with 62) as well as I-684 but thought why not let everyone have a crack.

According to this map US-95 Hits Arizona Twice.

But sections os US-95 in Arizona is shown as a state route.

[corco]

Yeah... thats because it is. US 95 goes from Mexico to Blythe, CA, leaving AZ concurrent with I 10. Arizona SR 95 has multiple segments, with one segment ending at the California line in Needles.

I guess we could start listing the 3di loops in metro areas near state lines, like I-275. It leaves Ohio for Kentucky and Indiana before returning to the Buckeye State. I don't suppose that's what the OP had in mind though.

[Alps]

US 611 used to leave PA at the Portland-Columbia Bridge and return at the Delaware Water Gap.

That US 52 section was built by and is maintained by West Virginia, similar to the NY 17/I-86 example above.

US 119 goes KY-WV (intersects US 52 just across the state line) KY-WV-KY-WV.

WV/VA 102 crosses the state line several times.

US 71 crosses the Red River from Arkansas into Texas, follows the state line and then re-enters Arkansas in downtown Texarkana.

I-49 is supposed to do the same thing, only taking a larger loop into Texas.

US 50 goes from MD to DC to VA to WV to MD to WV.

I've always enjoyed this example, most notably because of how US 50 goes through three other places between its two Maryland segments (DC, VA, and WV).

Are there even any other examples where a route goes through two other states between segments of another state?

US 72 mentioned above exits Tennessee, goes through Mississippi and Alabama before returning to Tennessee.

That it does...thanks for the reminder!

And of course, it's those "long" states, like Maryland or Tennessee, that really allow this possibility in the first place.

[dgolub]

NY 120A crosses over into Connecticut and then back into New York.

[US 41]

When I-49 is finished it will go from Arkansas to Texas and back into Arkansas.

According to its SLD, NJ Secondary Route 501 does as well, concurrent for much of the route. NJ was planning for New York getting tired of Staten Island and ceding it to NJ, I guess...
