Shortest state highways in multiple counties?

[KCRoadFan]

I was just curious: either by state or overall, what are the shortest state highways that go through more than one county within their respective states (i.e. they cross at least one county line)?

I know that here in the KC metro, MO 9 goes through Platte and Clay counties, with a small section at the south end in Jackson County. Overall, it only covers 14 miles - but it's a major route within the Northland.

IN 645 is 1.97 miles long and crosses the Martin/Daviess County line.

[Mapmikey]

VA 345 is 0.49 miles long and crosses a county line

[DJDBVT]

VT 64 runs for 6.77 miles, crossing the Orange/Washington County line.

[US 89]

Utah SR 168 is 1.160 miles and just barely crosses the Weber/Davis County line before dead ending at a closed gate to Hill AFB.

Shortest one in Colorado is CO53 which is 1.66 miles long and is on the border of Denver and Adams Counties.

Shortest one in Colorado is CO75 which is 3.237 miles long and goes between Jefferson and Arapahoe Counties.

Shortest one I'm seeing in Wyoming (with much larger counties) is WY235 which is 4.49 miles long and in Lincoln and Sublette Counties.

Georgia 228: three counties over 10 total miles (Schley, Sumter, Macon)

Georgia 153: four counties over 19 total miles (Webster, Marion, Schley, Sumter)

NJ 173 as it's around 15 miles and serves two counties, Hunterdon and Warren.  In NJ that would be the second shortest.

NJ 181 between Morris and Sussex Counties is the shortest.

Unless I missed one, the shortest state route in NY to pass through multiple counties is NY 32A, which is 1.9 miles in length and enters both Ulster and Greene counties.

NY 272 is also notable, as it's only 7.5 miles in length and straddles the Monroe/Orleans county line for its entire length.

Unsigned WV-6 (Earl M. Vickers Bridge) in downtown Montgomery in Fayette County and crosses into Kanawha County at the low water mark on the Montgomery side of the Kanawha River.  Total length is 0.6 miles.  I don't know the history, but it looks like the county line is gerrymandered to keep all of downtown Montgomery and the former West Virginia Tech campus within Fayette County.  Otherwise, the entirety of the Vickers Bridge would be in Kanawha County.

In a nomination for the "longest" shortest highway that's in multiple counties - AK8 is 135 miles long and travels through Denali, Matanuska-Susitna, and Copper River Boroughs/Census Areas.

VA 307 passes through three counties (Prince Edward, Nottoway, Amelia) in 9 miles.

Shortest I've found in MI is M-42, 10.3 miles, in Wexford and Missaukee.

Followed by M-117, 14.5 miles, Mackinac and Luce; M-179, 16.9 miles, Allegan and Barry.

The starting point of NC-128 (Mount Mitchell Scenic Drive) is near MM-355 of the Blue Ridge Parkway, which is located on the border between Yancey and Buncombe counties.  Since the Blue Ridge Parkway is not part of the state highway system, the official start point is beyond the Parkway right-of-way, so that all 4.6 miles of NC-128 are technically within Yancey County.

CT 55 is 2.64 miles long (a continuation of the much longer NY 55) and serves Sherman in Fairfield County and New Milford in Litchfield County.

[US20IL64]

For Chicagoland:

IL-390, thus far, is only 9.8 miles long, serves only Cook and DuPage Cos.

Next shortest in IL-394, at 14.6 mi. Cook and Will Cos.

Shortest I've found in MI is M-42, 10.3 miles, in Wexford and Missaukee.

Followed by M-117, 14.5 miles, Mackinac and Luce; M-179, 16.9 miles, Allegan and Barry.

Looks like M-188 is only 4.559 miles long and runs right on the border of Eaton and Ingham Counties.

California:

CA-275 (historic US-40) is now just .14 miles long (the Tower Bridge) and crosses the Yolo-Sacramento County line. It's unsigned, though.

Shortest signed one I can come up with is CA-220, about 6 miles between Sacramento and Solano Counties (includes the J-Mack Ferry across the Steamboat Slough, which is where it crosses the county line).

In the same state, MO 370 beats MO 9 by about a mile, at 13 miles long. Though there's likely to be one even shorter, I haven't checked.

Idaho: ID50 is 8.092 miles long and goes between Jerome and Twin Falls Counties
Montana: MT64 is 9.039 miles long and goes between Madison and Gallatin Counties
New Mexico: NM539 is 5.840 miles long and goes between Rio Arriba and San Juan Counties
