All lanes of I-75 to close from Eight Mile to Square Lake Road

All north- and southbound lanes of Interstate 75 will close so crews can set bridge beams 11 p.m. Friday, May 15,  reopening at 5 a.m. Monday, May 18. 

Motorists will continue to drive on just two lanes for north- and southbound traffic on I-75 between 13 Mile Road and Coolidge Highway while work is completed this spring, summer and fall. 

The closure is needed to set bridge beams at John R and Meyers roads over I-75. 

Suggested detours are Woodward Avenue, Eight Mile Road and Square Lake Road. 

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. 

Prep work on the third and final phase — from 13 Mile Road to Eight Mile Road, is scheduled to start this fall. The anticipated completion is fall 2023.
