April 10, 2019 -- Michigan Department of Transportation (MDOT) contracting crews will be closing both directions of Coolidge Highway under I-75 for bridge demolition starting at 10 p.m. Friday, April 12. The closure is needed to allow for the demolition of the bridge that carries northbound I-75 over Coolidge Highway. Currently, both directions of I-75 have two lanes open with all traffic using the southbound side of the freeway, separated by a temporary concrete barrier. This configuration will allow for the northbound lanes and bridges to be reconstructed this year and is expected to remain in place until late November.

During the closure, traffic on northbound Coolidge Highway will be directed to use Long Lake, Crooks and Square Lake roads. For southbound traffic, the posted detour uses Square Lake, Adams and Long Lake roads. Both directions of Coolidge Highway will reopen by 5 a.m. Monday, April 15.

This $224 million project involves reconstructing more than 8 miles of pavement, improving 18 structures, upgrading drainage, constructing community-developed aesthetics and federally approved noise walls, and continuing construction of the high-occupancy vehicle (HOV) lanes between Coolidge Highway and 13 Mile Road.

The entire I-75 modernization project involves rebuilding approximately 18 miles of pavement, replacing bridges, adding an HOV lane in each direction, and bringing the freeway up to current design standards from north of M-102 (Eight Mile Road) to South Boulevard.
