Coolidge Highway Under I-75 In Oakland County To Close Friday

Lansing, MI - Michigan Department of Transportation (MDOT) contracting crews will be closing both directions of Coolidge Highway under I-75 for bridge demolition starting at 9 a.m. Friday, May 1.

The closure is needed to allow for the demolition of the southbound I-75 bridge over Coolidge Highway.

Currently, both directions of I-75 have two lanes open with all traffic using the northbound side of the freeway, separated by a temporary concrete barrier, between 13 Mile and Adams roads. This configuration will allow for the southbound lanes and bridges to be reconstructed this year. I-75 traffic will not be impacted by the bridge demolition.

During the closure, northbound Coolidge Highway traffic 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. After the demolition work is completed, southbound Coolidge Highway will remain closed until the end of June. Through-traffic will follow the posted detour. Access to residential streets will be maintained. Northbound Coolidge Highway will have one lane reopen by 5 p.m. Sunday, May 3.
