Shortest highways

[mrcmc888]

Tennessee has TN-51 at 1.91 miles.

Delaware- DE-491, 0.36 mi.  Not signed.

In Pennsylvania, PA-299 is .052 mi.  It only covers one bridge in Erie.  It's baffling to me why, when its old route was destroyed by the airport, it was kept on this tiny segment instead of fully decommissioned.  If PADOT really wanted to keep it around, they could have designated Powell Ave-20th Street-Marshall Dr as the highway, seeing that it does what the route's old alignment did.

Kentucky's shortest is KY-410 in Greenup near the Ohio border.

Miller Park Way in Milwaukee has a 1.0 mile freeway segment that used to have an unsigned designation as WIS 341, back before it was decommissioned in 2015. It basically links I-94 with Miller Park and WIS 59 (National Ave), before continuing on as a surface street. The freeway is still there, but the highway number was removed.

Also in Milwaukee is WIS 119, which connects I-94/41 to the Mitchell Airport. At a length of only 1.89 mi, I believe this is the shortest highway in Wisconsin.

Another really short highway in Wisconsin would have to be WIS 30, which connects US 151 with I-39/90 and I-94, and serves as a direct route from I-94 into Madison.

Here is a really short highway in Nebraska that a fellow road enthusiast and i found in 2002.

Whenever I see a topic like this, I'm instantly reminded of IN-520.  Glad people covered that upthread.

In Illinois, it's probably Wisconsin 35's connector road, IL-35.  It's about 2 miles long.  IL-136 is a similar situation connecting to IA-136, and it's also very short.

I think there is some highway in Kentucky that is 37 feet long.  I don't know what the shortest *signed* highway is.

What What only 37 feet?


https://en.wikipedia.org/wiki/List_of_state_highways_in_Kentucky_shorter_than_one_mile


But Kentucky 410 is the shortest signed route in the state.

"Special route?" That must be a Wiki-made-up term because never, ever, in my life have I heard that term used. Has anyone else ever heard of such a thing?

Current MA 15 (not the one that is I-84) in Seekonk: an 0.23 mi unsigned continuation of RI 15 in Seekonk.  Shortest signed MA route is MA 108, a continuation of NH 108, at 0.91 mi.  Didn't see a reassurance shield on the route itself, but there is an LGS on MA 110.   NH 121A has a 260 foot section that ducks into MA, so it would technically be the shortest route overall in MA, and there is even a MA style LGS with a MA 121A route shield on MA 125, but the signage at the southern terminus, despite being in MA, is NH type signage, so I would imagine NHDOT would be responsible for maintenance.


RI 114A is the shortest route in RI and is signed on RI 114 and River Rd at intersections, but not on the road itself.  You can see the white paddle town MA town line sign from its terminus.


NH is NH 10A at 0.547 mi.  There is a reassurance shield eastbound, and when combined with the 0.522 mile VT 10A (which also has a reassurance shield),  it has to be the shortest multi-state route at about 1.07 mi.  All 69 feet of VT 26 isn't signed on the route itself (there is a NH 26 shield within view), but there are VT 26 shields on VT 102; a green and white one NB and a black and white one SB.

So odd.  It almost looks like somebody swiped the shield and hung it up at the gate.  Why TxDOT would leave it as a floating/unconnected SH, just baffles me.  But both links are the same spot.

[froggie]

All 69 feet of VT 26 isn't signed on the route itself (there is a NH 26 shield within view), but there are VT 26 shields on VT 102; a green and white one NB and a black and white one SB.

VTrans replaced all signage at the 26/102 junction two years ago.  All shields are now the modern green-on-white standard.

A state cemetery road is signed, but not the roads immediately surrounding the state capitol. Keep Austin Weird.

I just walked the length of FM 742 last week, so along with Mississippi Highway 702, and Florida State Road 800, I have a short list of clinched-on-foot routes.

Tennessee has TN-51 at 1.91 miles.

Delaware- DE-491, 0.36 mi.  Not signed.

In Pennsylvania, PA-299 is .052 mi.  It only covers one bridge in Erie.  It's baffling to me why, when its old route was destroyed by the airport, it was kept on this tiny segment instead of fully decommissioned.  If PADOT really wanted to keep it around, they could have designated Powell Ave-20th Street-Marshall Dr as the highway, seeing that it does what the route's old alignment did.

Kentucky's shortest is KY-410 in Greenup near the Ohio border.

PennDOT owns the bridge, and all PennDOT-owned bridges keep an unsigned SR number...usually a quadrant number (1000-4999).  In this case, since the bridge was already assigned SR 0299 as part of the signed route, the route became unsigned but the bridge kept the SR 0299 unsigned inventory number.

Delaware- DE-491, 0.36 mi.  Not signed.

I wouldn't say it's completely unsigned. There is only a single DE 491 shield, however, and it's posted along DE 92 (Naamans Road) approaching the routes southern end.

Another really short highway in Wisconsin would have to be WIS 30, which connects US 151 with I-39/90 and I-94, and serves as a direct route from I-94 into Madison.

WI243 is the shortest highway in Wisconsin.  It is less than a half-mile long.

They come up in 2 different spots when I click them - one is the Comal St gate and the other is off 11th.

With a designation of 243 I would think it would be in the Milwaukee area, next to I-43. There's also a 1.2 mile long segment of 243 in Minnesota as well. Still, I was just going off of my personal knowledge, and I've never been to that part of Wisconsin/Minnesota so I wouldn't know.

It's numbered for MN-243, which is also the legislative route number for the Minnesota portion of the highway.

Speaking of short state highways, just did a feature on NM 2001 which was/is only 0.3 miles long.  It isn't really clear if NM 2001 still technically exists but it would be the second shortest state route in New Mexico only behind NM 446:

OK, I'll look again.  May be my computer.  Or me.

Didn't occur to me until today but both AZ 95S routes are slightly shorter than AZ 24:

Makes more sense but it's still pretty confusing why PA-299 wouldn't still be assigned to the whole road the bridge is currently on since it covers much the same route the old one did.

CA-141 in Vallejo it was once part of alignment of Curtola Parkway, the western terminus of I-780, Mare Island Parkway and Wilson Ave. It's the shortest CA route in Vallejo.

CA-141 in Vallejo it was once part of alignment of Curtola Parkway, the western terminus of I-780, Mare Island Parkway and Wilson Ave. It's the shortest CA route in Vallejo.

That former routing appears to be about four miles long. Even if it weren't decommissioned three decades ago, hardly worth mentioning since there are existing routes just in California that are much shorter (including signed CA 153 and unsigned CA 275 and CA 283, all less than one mile long).

California actually has a lot of small little connector routes of similar length.  218, 219, and 233 all come to mind somewhat locally to me.  Most were unsigned until 1964.
