I-375 — a major gateway to Downtown Detroit is coming due for major repairs soon, so the Michigan Department of Transportation and the Detroit Downtown Development Authority (DDA) are asking the question, “Does the current configuration of I-375 really serve the needs of Detroit today – and into the foreseeable future?”

The opportunity to reconfigure I-375 comes at a time of substantial investments and anticipated development in the central business and waterfront districts, and coincides with the anticipated need for substantial repairs on the bridges over I-375 and other maintenance work in the near future.

The DDA has approved a planning contract with Parsons Brinckerhoff Michigan, Inc. to develop a set of alternatives to the I-375 corridor that connects I-75 to Downtown Detroit.

The Michigan Department of Transportation (MDOT) and other sources are paying for the $373,000 study, which will require traffic studies, stakeholder input, and developing concepts for five alternatives to the current configuration of I-375 from its intersection with Gratiot Ave. to Atwater St. Parsons Brinckerhoff is also expected to deliver an analysis of each option, including an economic analysis, traffic and environmental impact study and an assessment of the public spaces created by each option.

This was the perfect time to step back and take a look at how this important gateway to Downtown should be developed to serve a revitalized Downtown and East Riverfront. The DDA and MDOT have no pre-conceived ideas about what I-375 should be, just a recognition that whatever we do will have important economic development consequences for decades to come.

Parsons Brinckerhoff is expected to spend the first month conducting research and gathering input from surrounding property owners, community representatives and other stakeholders. The schedule anticipates Parsons Brinckerhoff will present the client group’s preferred alternative no later than July 2014.

Ed Tatem, Michigan President of Parsons Brinckerhoff says, “We are very excited to be responsible for studying traffic, gathering input from all stakeholders — including commuters — and presenting fresh ideas for this significant project.”

Kelby Wallace, MDOT Project Manager says, “The potential to transform this corridor will need to fit the future vision of the city, that is why the study is engaging numerous partners and investigating all options.”
