Interstate 375 (I-375) in Detroit, at only in length, once had the distinction of being the shortest signed Interstate Highway in the country. It is the southernmost leg of the Walter P. Chrysler Freeway and a spur of I-75 into downtown Detroit, ending at the unsigned Business Spur Interstate 375 (BS I-375), better known as Jefferson Avenue. The freeway opened on June 12, 1964. The Michigan Department of Transportation (MDOT) announced in 2013 that it may remove I-375 in the future.
