Interstate 375 (I-375) is a north–south auxiliary Interstate Highway in the city of Detroit, Michigan, United States. It is the southernmost leg of the Walter P. Chrysler Freeway and a spur of I-75 into Downtown Detroit, ending at the unsigned (BS I-375), better known as Jefferson Avenue. The freeway opened on June 12, 1964. At only 1.062 miles (1.709 km) in length, it once had the distinction of being the shortest signed Interstate Highway in the country before I-110 in El Paso, Texas, was signed. The Michigan Department of Transportation (MDOT) announced in 2013 that it may remove I-375 in the future, and in 2021 the department announced plans to move forward converting the freeway to a boulevard.
