Shortest highways

[Voyager]

CA 151

CA 263

What else can anyone think of?

What is the point of having highways that are incredibly short and could easily be replaced with a business loop but most of the time are just signed with them?

SR 433 (WA) - 0.94 mi
SR 543 (WA) - 1.03 mi

31 miles long.

A lot of times they'll serve a bridge, correctional facility, state park, dam, or other governmental facility. Also lots of old alignments along freeways ends up getting state highway designation once downgraded from their former status.

WYO 74 in Wyoming only exists so that the bridge in Saratoga Wyoming is under state maintenance, WYO 14 serves the Laramie Airport, WYO 376 serves the Rock Springs Airport, and there are several other instances. All of those are less than half a mile long.

Wyoming itself has a ton of routes with no functional purpose that are short and dead end. It's almost like every paved county highway is state maintained, because the pavement always ends at the end of these roads, although in many instances it is very unclear as to why they are paved.

Washington State has several short spurs to state parks (SR 300), correctional facilities (SR 102), DOT yards (SR 504 Spur), viewpoints (SR 174 Spur), ferry terminals (SR 163), and things like that.

Idaho is incredibly good about not having ANY of these.

As far as the business loop question, a lot of old frontage roads don't serve anything of significant size to get AAHSTO approval as a business loop, but are still within state jurisdiction. I'd assume the multiplexed ones don't really need to be signed but are because most states categorize their business loops under separate reference designations to avoid confusion, and sometimes those signs bleed out to the public, either on purpose or on accident.

From the North Carolina DOT map:

North Carolina 400 at 0.93 miles in Manteo.

SR 331 (Forest Parkway) - This route is 3 miles long, connecting SR 85 and I-75 with SR 54 (Jonesboro Road). It also provides access to the State Farmer's Market. The road continues east of SR 54, as a county road, to East Atlanta Road -- changing names to Panola (Clayton County) and West Panola Roads (Henry County) respectively. The route continues west past SR 85 (as a county/city road), down old Sullivan Road, dead-ending into I-85. It changes names to Phoenix Boulevard and Godby Road in the process.

The shortest Interstate x0 is I-30 at 367 miles, from just west of Fort Worth, TX to North Little Rock, AR.

[Voyager]

What about I-97?

[akotchi]

N.J. 59, at 0.15 miles.

Well Ontario's shortest is quite long (about 50km), but the historical shortest was deleted in 1997, it was 12 km long.

VA 283(its already posted only as US 58 ALT Business so why can't it just be US 58 ALT Business)

Nevada's shortest highway is SR 646/Prater Way in Sparks.  From just west of N. McCarran Blvd to N. McCarran Blvd, it is 0.090 mi (~475.2 ft) long.  I believe the only reason it is in the system as a state route is because NDOT owns that little bit of road, and it not near an interchange or other facility that could qualify it as a frontage road.

Another short one, actually shorter, is what's left of SR 663/Sierra Street in Reno.  At 0.055 mi (~290.4 ft), it now solely consists of the Sierra St bridge over I-80.

The shortest state route in Michigan is:

M-212 at 0.72 mile

Google map: http://maps.google.com/maps?f=q&source=s_q&hl=en&geocode=&q=aloha,+mi&sll=37.0625,-95.677068&sspn=34.176059,56.25&ie=UTF8&ll=45.525713,-84.455509&spn=0.029525,0.054932&z=14

M-212 runs from M-33 to Aloha State Park.  Many of Michigan's shortest state routes end at state parks.

Neither are signed (no routes numbered 400+ are).

The shortest signed state route in Connecticut is CT 125, at 1.24 miles.

[ctsignguy]

shortest route to my knowledge in Ohio is US 25....crosses the Ohio River from Covington KY to Cincinnati...and dies right at the end of the bridge, just a couple hundred feet into Ohio!
