Interstate through Chicago (6)

I believe the answer is:

ninety

(Other definitions for ninety that I've seen before include "''Oh, the craic was ... in the Isle of Man'' (The Dubliners)" , "XC in Roman numerals" , "Joe perhaps" , "Minutes in a soccer game" , "Figure in inn, yet, strangely" .)

I've seen this clue in the LA Times.
