Interstate 475 (I-475) is a north–south auxiliary Interstate Highway in the US state of Michigan. I-475 is a 16.9-mile (27.2 km) bypass route that serves the downtown area of Flint while its parent, I-75, passes through the west side of the city. I-475 starts southwest of Grand Blanc and runs through suburbs of Flint before passing through downtown. There, it intersects I-69 and crosses the Flint River. The freeway turns westerly to connect back to I-75 north of Flint near Mount Morris.
This component freeway of the State Trunkline Highway System was planned in the 1950s and built in the 1970s. The trunkline was first named the Buick Freeway to honor David Dunbar Buick's contributions to Flint's early automotive industry as founder of Buick Motor Company. I-475 was renamed in 1981 the UAW Freeway, honoring the United Auto Workers, a labor union which was active in Flint. At the same time, the name of I-69 in Flint was changed from the "Chevrolet Freeway" to the "Chevrolet-Buick Freeway". Since 2001, I-475 has borne both the UAW and Buick names officially.
