Interstate 375 (Michigan)
The 1.15 mile Interstate 375 in Detroit has the distinction of being one of the shortest signed Interstate Highways. I-375 is the southernmost leg of the Walter P. Chrysler Freeway and is a spur off of I-75 into downtown.
The unsigned 0.015 mile-long Business Spur Interstate 375 (BS I-375) continues west on Jefferson Avenue from the southern end of I-375, ending at the entrance to the Detroit-Windsor Tunnel at Randolph Street (M-3). Jefferson Avenue past that intersection is M-10, quickly becoming the Lodge Freeway.
