Highways that just miss state lines (deal, build, island)

[General I80]

Interstate 8 in CA goes below 1800 feet from Mexico (here)

Interstate 19 in AZ ends 100 meters before entering Mexico in Nogales.

US-151 used to go through Illinoia, but now follows a new bridge going directly from Iowa to Wisconsin.

You can see the Mexican border wall from I-8 in parts of Imperial County, California.

The 8 replaced US highway 80. Along the old highway 80, you get really close to the border wall.

Interstate 64 and Ohio are only a mile apart just west of Huntington, West Virginia.

I don't know if this counts, but I-684 cuts the corner of Connecticut, with no exits or entrances. New York plows the snow and otherwise maintains the road.

That's actually more interesting than this thread's standard examples.

So people who live or own land across the road have to go to New York to one of the exits to get across the road legally back into Connecticut.

According to Google, US-71 drifts a few meters into Teas, a few miles north of Texarkana, and from there to the Red River bridge. My first time in Texas was hitching up 71, and I walked across the road just to make sure.

That would be true, except that the land is uninhabitable. I think it's wetlands.
