→At only 1.062 miles (1.71 km) in length, Interstate 375 (I-375) in Detroit has the distinction of being the shortest signed Interstate Highway that is up to Interstate Standards. Only I-110 and the unsigned I-878 and I-315 are shorter.[3] I-375 is the southernmost leg of the Walter P. Chrysler Freeway. It is a spur off of I-75 into downtown Detroit to end at the unsigned Business Spur Interstate 375 (BS I-375), better known as Jefferson Avenue. The freeway opened on June 12, 1964.

Route description [edit]
I-375 and the Chrysler Freeway begin at Jefferson Avenue and St. Antoine Street in downtown Detroit near the Renaissance Center.[4] They run east before turning north. Just about a mile (1.6 km) after the southern terminus, I-375 meets the Fisher Freeway which carries I-75 north of downtown. At this interchange, I-75 takes ramps to leave the Fisher Freeway and use the Chrysler Freeway, replacing I-375. I-375 is a four-lane freeway the entire length.[5] The entire length of I-375 is included on the National Highway System,[6] a network of roadways that are the country's most important roads.[7]
According to the Michigan Department of Transportation (MDOT), I-375 is 1.062 miles (1.709 km).[2] Based on FHWA data, there are three Interstates that are shorter: I-110 in Texas (0.92 mi or 1.48 km), I-878 in New York (0.70 mi or 1.13 km) and I-315 in Montana (0.83 mi or 1.34 km).[3] The latter two designations are not signed on their respective roadways.[8]
Every year, MDOT conducts a series of surveys on its highways in the state to measure traffic volume. This is expressed in terms of average annual daily traffic (AADT), which is a measure of traffic volume for any average day of the year. In 2009, MDOT calculated that 14,112 vehicles per day used the southernmost section of I-375, and 53,900 vehicles used the northernmost section near I-75. These vehicles included 798 trucks.[9]
History [edit]
Construction on the first segments of the Chrysler Freeway started on January 30, 1959. These segments were opened to traffic on June 26, 1964.[1] The southern most segment was designated I-375 at this time.[10]

The unsigned Business Spur Interstate 375 (BS I-375), which is 0.167 miles (0.269 km) long, 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.[2] BS I-375 runs next to the Renaissance Center and under a segment of the People Mover.[5] This designation was created in 1964.[11] The 2009 traffic surveys by MDOT reported that 33,376 vehicles, including 922 trucks, had used BS I-375.[9]
