Long state highway in one state ties into very short highway in another

[andrepoiy]

Quebec Route 124 is 326 km.
It becomes Highway 124 in Ontario, a good 7 km in length.

[DandyDan]

K-27 runs for 226 miles in Kansas, then turns into the southern segment of Nebraska Highway 27, which runs for 0.78 miles to US 34.

K-99 goes from the Oklahoma border to the Nebraska border. NE 99 then only goes 13 miles north.

[7/8]

Quebec Route 124 148 is 326 km.
It becomes Highway 124 148 in Ontario, a good 7 km in length.

FTFY.

Another example: QC 141 (80.8 km) becomes VT 141 (only 0.8 km).

whooops my bad, funny you knew what I was talking about

US 195 goes 93 miles in WA, while it is only half a mile in ID.

[1995hoo]

NC/VA 87: 239 miles in NC, 4 in VA.

Less notable but similar:

NC/VA-86 has 53.1 miles in North Carolina and 3.33 in Virginia.
NC/VA-96 has 112 miles in North Carolina and 7.83 in Virginia.

[SkyPesos]

US 195 goes 93 miles in WA, while it is only half a mile in ID.

US 131: 269.32 miles in MI, 0.64 miles in IN

[Bruce]

US 195 goes 93 miles in WA, while it is only half a mile in ID.

And before US 95 was rebuilt at the south end of US 195, it too had an absurdly short section. US 95 in WA was barely 1 mile long between its two sections in ID, which total 539 miles long.

[BrianP]

MD 97 is 55 miles and PA 97 is only 9.3.
US 222 is 91 miles in PA and 3.6 in MD
This one is fun since it involves three states and four segments with the longest and really short shortest in the same state:
US 340
17 miles in MD
0.6 miles in VA
16.4 miles in WV
116 miles in VA again.

OR 35 and WA 35 (US 26 on Mt Hood to WA 14), in a debatable example, as WA 35 isn't signed on the Washington side of the Hood River Bridge.
Bonus: ORH 26 and WA 35, extending the Oregon side west to the west end of the Ross Island Bridge.

Also: OR/ID 52, with the Oregon portion being the extremely short end.

K-99 goes from the Oklahoma border to the Nebraska border. NE 99 then only goes 13 miles north.

And it crosses Oklahoma from north to south too. It no longer connects to Texas 99, however.

West Virginia's best example is one that disappears in Maryland.  WV-28, which runs 151 miles from Huntersville (WV-39) to almost Ridgeley, then enters Cumberland on the Canal Parkway (unsigned MD-61) that is only 1.9 miles long.  I shouldn't include this wimpy one is WV-37, which is a tad more than 39 miles and crosses the Big Sandy River to become Spur KY-3, which is a microscopic 280 feet long.

In addition to the OH-32 example, there are some not so impressive short stubby intrusions into West Virginia:  PA-21 is only about 51 miles, which changes over to WV-891 that is a mere 2.3 miles long.  My favorite is VA-311 that runs only about 42 miles then enters West Virginia with the same number (WV-311), which clocks in at an even 4 miles (this was extended into West Virginia as a result of multiplexing US-60 onto the eventual path of I-64). 

Dishonorable mention is VA-259/WV-259, which runs about 27 miles in Virginia, runs about 45.5 miles in West Virginia, then crosses back over in Virginia for not quite 5 miles.

[hbelkins]

VA 160 just runs from VA 68 near Appalachia to the state line, but KY 160 continues through Harlan, Letcher, and Knott counties for a significant distance.

[US 89]

International border, but in the same vein so I say it counts. US 395 travels for over 1300 miles through four states… and then crosses into British Columbia, where it continues as BC 395 and then ends after just 2.5 miles.

[SD Mapman]

K-27 runs for 226 miles in Kansas, then turns into the southern segment of Nebraska Highway 27, which runs for 0.78 miles to US 34.

And even if they connected all the N-27 segments, it would hit SD and become the roughly 3.5 mi SD 391.

Also in the same area, you have WY/NE/IA/IL 92, which is around 100 miles in Illinois, 280 miles in Iowa, 490 miles in Nebraska, and a measly 17 miles in Wyoming.

[jay8g]

Not as extreme as many of these, but still amusing: ID 41 (39 miles) turns into WA 41 (0.4 miles) -- southbound only. The north end of the highway runs along the state line, and for some reason, the southbound lane got its own unsigned Washington state route number (though it appears to be fully maintained by Idaho).

[OCGuy81]

Could you count I-41?

176 miles in Wisconsin and less than a mile in Illinois.

[Flint1979]

I know OH-49 is 153 miles long and starts in Trotwood just west of Dayton and travels up to the Michigan state line and becomes M-49 (the only state highway in Michigan to continue as the same highway number from another state). M-49 ends 25 miles into the state so this might not be the most extreme but M-49 most certainly is nowhere nearly as long as OH-49.

[plain]

US 58 runs 508 miles in VA → barely 1/2 mile in TN

US 206 runs nearly 130 miles in NJ → under 1/2 mile in PA

DE 1 runs 102 miles → MD 528 runs 9 miles

[DandyDan]

MN 210 runs for 228 miles and ND 210 runs for 3.

[Roadgeekteen]

Not that much but 8.3 mile RI 15 becomes 0.23 mile MA 15.

[jp the roadgeek]

Can't believe I forgot this one:

DE 896: 21.13 miles
MD 896: 0.21 miles
PA 896: 33.772 miles
