Interstate 275 (I-275) in the US state of Michigan is a western bypass around the Detroit metropolitan area, completed on January 14, 1977. The freeway is maintained by the Michigan Department of Transportation as part of the larger state trunkline highway system. It runs through the western suburbs near Detroit Metropolitan Wayne County Airport, terminating in an interchange with I-75 near Newport, northeast of Monroe. Early planning maps for the Interstate Highway System in the 1950s included a highway roughly parallel to the modern I-275. As plans developed through the 1960s and into the early 1970s, the freeway was to run from I-75 near Newport north to Novi and connect back to I-75 near Davisburg, but the state canceled the northern section after local opposition. Additional plans to extend the highway through Oakland County were kept on the drawing boards through the 1980s, but failed to materialize. Highway M-5, the Haggerty Connector, opened along part of the former I-275/M-275 right-of-way between 1994 and 2000. (Full article...)
