Interstate Highways That Don't Cross State Lines

Wouldn't you think an interstate highway would have to serve at least two states? Well, there are 13 major highways that don't leave the state they start in.
Only 1- and 2-digit interstates (so no I-405).
Alaskan, Hawaiian and Puerto Rican interstates don't count.
I-86 and I-88 aren't listed here because there are multiple interstates with those numbers.
