The headache has begun for commuters who drive on southbound I-75 in Oakland County. A massive, two-year construction project closed the freeway between Detroit and Downriver this weekend.

The $200 million project includes replacing all of the concrete on the I-75 Rouge River bridge, the largest concrete surface in the entire state.

According to WDIV, MDOT's plan for the project includes:

  • Removing and replacing all concrete on the I-75 Rouge River bridge, the largest concrete surface in Michigan (approximately 20 football fields).
  • Replacing concrete on the I-75 bridge at Fort Street, south of Springwells Road.
  • Removing the Goddard Street bridge over I-75 and replacing it with two smaller bridges.
  • Repairing 13 other bridges along I-75 through the Downriver communities.
  • Adding intelligent transportation system (ITS) equipment. ITS includes a combination of electronic, telecommunication and information technology MDOT uses to improve safety and travel times on the transportation system.

Northbound I-75 will remain open during the project.
