What are the shortest and longest numbered highways in Hawaii?
The shortest numbered route is unsigned 0.03 mile-long state route 442 on Lanai, a short spur toward Lanai City from state route 440. I don’t know whether it is signed, but it wasn’t on my last visit in 2001. The shortest signed state route (unless route 442 turns out to be signed — I know Hawaii’s other mini-routes are unsigned) is state route 32A (Hobron Street) on Maui, at 0.41 miles. The longest numbered highway is state route 11 on the Big Island, at 122.09 miles.
