This $224 million project will involve 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.
Initially, the construction impacts will begin after morning rush hour on the southbound lanes from Adams Road to south of 13 Mile Road as crews begin preparations for a traffic shift. By Friday morning, around-the-clock lane closures will be in place with southbound traffic using the right shoulder as a travel lane. By mid-March, it is expected that all traffic will be carried on the southbound side of the freeway. Two lanes will be open in each direction with a temporary concrete barrier separating northbound and southbound traffic. Temporary exits will be maintained for northbound traffic at various locations. A crossover at an entrance ramp will allow traffic to access northbound I-75 while traffic is shifted onto the southbound lanes.
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.
MDOT has previously partnered with 3M on the I-75 modernization project to transform the Oakland County work zone over a 3-mile stretch to improve safety for drivers and to test advanced vehicle-to-infrastructure technologies for connected and autonomous vehicles.
