Lanes of I-75 will close tonight from Square Lake to 14 Mile

Traffic lanes on northbound Interstate 75 from Big Beaver Road to Crooks Road are set to be closed, depending on the weather, 9:30 p.m.-5 a.m. July 10-11.

The southbound lanes of I-75 will also be closed from Square Lake Road to 14 Mile Road 9:30 p.m.-5 a.m. July 10-11.

The closures are needed so crews can set new bridge beams on the overpass at Wattles Road. 

Suggested detours for northbound traffic are Big Beaver and Crooks roads to westbound M-59 to northbound I-75. Detours for southbound traffic are Square Lake Road to Woodward Avenue to eastbound I-696, then back to southbound I-75. 

Currently, both directions of I-75 traffic, separated by a temporary concrete barrier, are maintained on the southbound side of the freeway. This will allow for the northbound 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.
