The I-75 Modernization project in Oakland County is approximately 18 miles in length and traverses through six communities: Auburn Hills, Bloomfield Township, Troy, Madison Heights, Royal Oak, and Hazel Park. It was built in the 1960s and has never had a major improvement since that time. This project will add a lane that will be used as High Occupancy Vehicle (HOV) in the peak hours of travel for carpoolers and transit vehicles, and then operate as a general lane for all to use, for the remaining hours. This will be the first HOV lane constructed in the State. The project will upgrade interchanges, reconstruct the existing freeway pavement, construct carpool lots, improve the drainage system, replace bridges, and include aesthetic enhancements to the corridor. The planned improvements will increase motorist safety, travel efficiency, and reliability. It will also address safety concerns, reduce congestion, relieve drainage issues, and improve the road and bridge condition. It is a critical route for local and intrastate goods movement, a key commercial and business route, a tourist route to Northern Michigan, and a local residential artery.
