Interstate 275 (I-275) is an Interstate in the U.S. state of Michigan that acts as a western bypass of the Detroit metropolitan area. The Michigan Department of Transportation (MDOT) maintains the highway. The freeway runs through the western suburbs near Detroit Metropolitan Wayne County Airport. The southern end is the interchange with I-75 near Newport. MDOT considers the Interstate to run to I-96, I-696 and M-5 on the Farmington Hills–Novi city line, running together with I-96 for about five miles (8.0 km). This gives a total length of about 35.03 miles (56.38 km). According to the Federal Highway Administration (FHWA), the length is 29.97 miles (48.23 km) because they consider I-275 to end at the junction with I-96 and M-14.
