Signed Routes that complete a full circle

[Max Rockatansky]

What signed routes out there form a complete 360 degree circle?  Obviously this would be something far more common freeway territory with Interstates like I-295 in Jacksonville and I-495 in the D.C.  M-185 on Mackinac Island comes as a state route example of a fully circular route.

Not-entirely-freeway example: KY 4

Another non-freeway example: AL-210 encircles Dothan, AL.

(I believe) NY 47 was a former example, looping around Rochester using both freeways and surface streets.

[US 89]

NV 659 (McCarran Blvd) forms an arterial beltway around Reno.

I-610 in Texas and I-285 in Atlanta area.

I'm quite sure it was a big U. No connection between the north ends.

I was not even alive during the time period when NY 47 existed 
So, I retract my statement.

Texas has many routes that complete a circle

[fillup420]

I-485 Charlotte

I-285 Atlanta

[paulthemapguy]

Columbus, Ohio has I-270.  San Antonio, Texas has I-410.  Kansas City has I-435.  Indianapolis has I-465.  I-465 used to also encompass the northwest stub currently known as I-865, so at one point, it revolved around the city for even more than 360 degrees.

Take a look at the Texas "loop" routes https://en.wikipedia.org/wiki/List_of_state_highway_loops_in_Texas

Prior to the mid-1990s, MA 127 in the Cape Ann area (Gloucester & Rockport) used to be a complete circle.  On a map, the route resembled a balloon with a long string (the Beverly to Gloucester stretch).  Today, with the truncation between MA 128 and Western Ave. (current MA 127), the route now resembles a small opening hook with a long stem.

I-435 around Kansas City
I-275 around Cincinnati
I-820 around Fort Worth
I-410 around San Antonio
I-440 around Raleigh

AR 180 once completed a circle around Mt Sequoyah at Fayetteville, AR before it was decommissioned

Georgia also has a couple of these. The best known is probably GA 10 Loop in Athens, which is almost, but not quite, entirely freeway. I believe GA 1 Loop in Rome is eventually planned to be a full circle, but isn't complete yet. A former example was GA 120 Loop in Marietta; this is now 120 on the south side and 120 Alt on the north side (120 previously went straight through on Roswell St, now partially GA 3 Conn).

Does QC 132 count?  It loops around and ends at itself in the Gaspé peninsula.  Of course, there is the long tail comprising the rest of the route west to NY.

In the "former" category would be MN 100, which originally completed a loop around both Minneapolis and St. Paul.  The western leg is all that remains today.  Parts of what are now (generally going clockwise) I-694, Ramsey CSAH 96, MN 120, I-494, MN 110, and MN 5 made up the loop.

I-440 around Raleigh

I-440 was removed from I-40, so it is no longer a complete circle

In western Canada, the recently-completed all-freeway AB 216 loop around Edmonton.

Circle Drive around Saskatoon misses out, since part is unnumbered, and two other parts have different route numbers (as best as I can figure out, given the total clusterfork that is route signage in Saskatoon).

Ditto Winnipeg's Perimeter Highway, which has different route numbers for its northern (PTH 101) and southern (Trans-Canada 100) halves.

Same story for I-820. The south section was replaced with I-20.

MA 127 used to, ending at itself just west of Gloucester center. It's "northern" end was truncated to MA 128 about 25 years ago.

I was alive, but I have no memory of it existing (other than those reference markers that still can be found). But I agree with the recollection that it never had a northern leg; NY (US) 104 and/or NY 18 filled that role.

I-695 around Baltimore.

TN-155 completes a full loop around Nashville but only about 3/4 of it is freeway (Briley Parkway).  A segment south of the city runs on a surface street.

Wow! I am surprised no one poked fun at this thread.  Amazing!

I-495, the Capital Beltway.
