Interstate 275 (abbreviated I-275) in the U.S. state of Michigan is a western bypass of the Detroit metropolitan area. According to the Federal Highway Administration (FHWA), the length is 29.97 miles while the Michigan Department of Transportation (MDOT) reports the length as 35.01 miles. This discrepancy is due to a disagreement over the northern terminus.

According to the FHWA, I-275 ends at the junction with I-96/M-14 along the boundary between Livonia and Plymouth Township. MDOT considers I-275 to extend north overlapping with I-96 to the junction with I-696 and M-5 along the boundary between Farmington Hills, Michigan and Novi, Michigan. Road signs and most maps support MDOT's view.

The southern terminus is the junction with I-75 in Newport, Michigan, northeast of Monroe, Michigan.

I-275's northern terminus is also the western terminus of I-696, making this junction one of the few (perhaps the only) points that is the terminus of two three-digit Interstate Highways with different parents. With the original planned northern terminus at I-75 near Davisburg abandoned because of local opposition, it appears that the current northern terminus of I-275 at I-696 will be permanent.

[edit] History

1968: The Michigan Department of Transportation and the Federal Highway Administration identify the routing of I-275/I-96 from 5 Mile Rd to the current Northern terminus at I-696.
1972: The remaining route from I-96 South to I-75 is identified.
1973: Construction begins on Phase I of I-275 between Ford Rd and Schoolcraft Ave.
1975: Phase I of I-275 is opened to traffic, construction commences on Phase II between I-96 and I-696.
1976: Phase II opens to traffic, construction commences on Phase III between Ford Rd and I-75.
1977: Phase III and the Jeffries Freeway opens to traffic and MDOT cancels phase IV which would have brought the freeway to its original destination, I-75 near Clarkston. Ramp stubs and bridges built at the new northern terminus to connect to phase IV remain unused for over 15 years.
1994: M-5 (Haggerty Connector) opens to traffic following the original route intended for I-275, M-5 is completed to 12 Mile Road as a fully-functional limited access freeway.
1999: M-5 is extended to 14 Mile Road as an expressway.
2002: M-5 expressway extended to Pontiac Trail in Commerce Township. MDOT officially cancels all future plans to extend the road any further north.
