BLOOMFIELD TOWNSHIP (WWJ) – Scheduled to span more than a decade, a nearly billion-dollar construction project to improve and widen I-75 in metro Detroit is now underway.

Construction started Monday on the effort with a 2-year, $90.8 million project to reconstruct both directions of I-75 between Coolidge Highway and South Boulevard in Oakland County. The project includes reconstructing pavement, replacing bridges and modernizing the Square Lake Road interchange — just the start of the first phase of the massive renovation from 8 Mile Road to South Blvd.

On Monday on southbound I-75: between M-59 and Square Lake Rd. the left lane is closed; between Square Lake Rd. and Crooks Rd. the right lane is closed.

According to the Michigan Department of Transportation, one lane on the southbound side will be closed continuously to prepare for a future traffic shift, while northbound I-75 will have intermittent single-lane closures from Coolidge Highway to South Blvd. in the coming days.

A new traffic configuration is expected to last into early September, when additional work on the project is scheduled to begin.

Annie Rosenborough of Detroit was among motorists not happy to hear about any of it.

“I’m going to have to get up a little bit earlier to get to work on time,” she told WWJ’s Charlie Langton.

The work is taking place in phases through 2030. Overall, the cost of the roughly 18-mile project is expected to top $1 billion.
