Two-way I-75 traffic shifts to southbound lanes between Eight Mile and I-696

Northbound Interstate 75 traffic will be reduced to one lane between Eight Mile Road and Interstate 696 to allow crews to shift two lanes of north- and southbound traffic to the southbound lanes beginning at  7 a.m. April 4. 

According to a press release from the Michigan Department of Transportation, two lanes of north- and southbound traffic will be open during peak travel times. 

The northbound ramp from I-75 to eastbound I-696 will close until early November as part of the Segment 3 portion of the I-75 modernization project, which spans from 13 Mile to Eight Mile. 

Suggested detours are Eight Mile Road to  Van Dyke Avenue, to eastbound I-696. 

The anticipated completion for Segment 3 is fall 2023. This phase will cost $630 million, bringing the overall project cost to $945 million.

Currently, both directions of I-75 traffic, separated by a temporary concrete barrier, are maintained on the newly constructed northbound side of the freeway. This will allow for the southbound lanes and bridges to be reconstructed this year. This configuration is expected to remain in place until late November. 

When completed, the $224 million project, the second phase of the I-75 modernization project, will reconstruct 8 miles of pavement and 18 structures, upgrade drainage and improve aesthetics. It will feature federally approved noise walls and a high-occupancy vehicle lane between Coolidge Highway and 13 Mile Road. 

Final pavement markings for the 8-mile segment through Troy will be finished in 2021.

The $127 million first phase of the project, the addition of one lane to northbound and southbound I-75, covered 3 miles of the freeway, between South Boulevard and Coolidge Highway through Bloomfield Township, Auburn Hills and Troy. That began in August 2016. The project’s first phase of construction also replaced five bridges, reconfigured the interchange at Square Lake Road and made improvements to the Adams Road carpool lot. 

That work was completed in 2017.

Federal funding covers about 80% of the costs. 

That stretch of freeway carries up to 174,000 vehicles per day.
