A study on reconfiguring Interstate 375 in downtown Detroit is being planned.

The Detroit Downtown Development Authority says Wednesday that it has approved a planning contract to develop alternatives to the current configuration of the 1-mile expressway from Gratiot Avenue to Atwater Street.

The freeway corridor connects I-75 to downtown. The state Department of Transportation and other sources will pay for the $373,000 study.

Downtown Development Authority officials say the chance to reconfigure the expressway comes "at the time of substantial investments and anticipated development in the central business and waterfront districts."

Bridges over I-375 also may be in line for substantial repairs in the near future.

Plans also are underway to add lanes to I-94 north of downtown Detroit and I-75 in the city's northern suburbs.
