Mound Road’s history as a national leader in manufacturing during WWII allows it to pivot to a corridor leading automotive innovation. Yet it needs a reconstruction to look and feel like the state-of-the-art technology corridor that it is.

The 40-year-old road surpasses the average roadway expectancy of 25 years and would require Macomb County to spend millions annually on maintenance and repairs. The total rebuild is far beyond a resurfacing project.

Innovate Mound will reconstruct approximately nine miles of Mound Road from 11 Mile Road to M-59, and add a fourth lane in each direction from 17 mile to M-59. It includes new concrete pavement, drainage, curbs and driveways, signal optimization, roadway widening, connecting vehicle and fiber optic communications technology, enhanced non-motorized facilities, and energy-efficient lighting.

After two and a half years of planning, design, and outreach, Macomb County and HNTB as the lead consultant will begin the construction phase with plans to break ground after Labor Day.
