HIghway With the Shortest Trip Through a Jurisdiction

[sbeaver44]

I-76/PA Tpk spends approximately 2.6 miles in Huntingdon County.  I know this isn't signed Westbound as the entry point is in the Tuscarora Tunnel and there's nothing after the tunnel.  I don't remember if Eastbound is signed.  It also doesn't spend too long in Berks County either.

US 30 spends about 2 miles in West Virginia.  As far as states go, that's got to be one if the lowest ratios of length in a state vs total highway length.

New York Route 419 is an entrance road to Watkins Glen State Park from NY 329.  It is 0.30 miles long.  I suspect we'll find a lot of these type of roads across the US.

NY 21 spends half a mile in Yates County.
NY 246 spends 0.1 mile in Genesee County.
NY 65 spends 0.25 miles in Livingston County.

When US 69 goes south out of Emmons, MN into Iowa, it goes through Worth County before entering  Winnebago County.

I-75 spends about three quarters of a mile in Hamtramck, MI with Detroit on both sides.

The segment between MD and WV is only about 0.6 miles long. The only other route that segment encounters is SR 671.

I-69 (formerly I-164) northbound around Evansville at about the 12-13 mile marker, there are two county signs about 100' apart.  Leave one county (Vanderburgh) enter another (Warrick) and quickly leave it for Vanderburgh again.

[-- US 175 --]

US 175, in the interchange where it crosses I-20 (and passes near I-635's southern (SE) terminus), leaves Dallas, passes through a tiny corner of Balch Springs in the middle of the interchange, then goes right back into Dallas.

If I remember correctly, doesn't IH 84 end at IH 90 like less than a mile into Massachusetts?

[1995hoo]

"IH"?

The city of Lakeside, Colorado is only about 2400' x 2400', so I guess it has 2400 feet worth each of I-70 and CO95.

"IH"?

Texas people have a tendency to say "IH" for interstates instead of "I."

If I remember correctly, doesn't IH 84 end at IH 90 like less than a mile into Massachusetts?

It's about 7 miles or so.

I think other than DC's I-95/495, the next shortest interstate in a state is I-129 only being in Iowa for 0.27 miles.  The other shortest 2di is I-78 in New York for 0.9 miles.

I-57 barely clips the northwest corner of Clay County, IL.  From north to south, it enters from Effingham County and leaves in to the eastern panhandle of Fayette County.  In this GSV, you can see the "Fayette County" sign in the distance, even with the fisheye lenses that Google uses, as you cross into Clay County going south. https://goo.gl/maps/vNk5npTf1sSGCqm76

The clip is so short that I initially didn't think I deserved to count Clay County in my county clinching from only driving I-57.  I drove US45 through the seat of Clay County (Louisville, pronounced "Louis-ville") in 2019, so there's no gray area anymore.

In western Kansas, between Oakley and Colby, I-70 angles northward for about 20 miles before leveling off again. It's on this angled stretch that it clips the northeast corner of Logan County, entering Thomas County to the north about a mile after coming in from Gove County, which is to the east.
