Michigan I-75 Modernization Project (Segment 3) Design Build Finance Maintain (DBFM)

I-75 from north of M-102 (8 Mile Road) to north of 13 Mile Road in the Cities of Hazel Park, Royal Oak, and Madison Heights located in Oakland County

Segment 3 consists of complete pavement reconstruction, modernization of the freeway, ITS upgrades, and replacement of 28 bridges (22 vehicle overpasses and ramps and 6 pedestrian structures). Additionally, the project will construct a 14-foot diameter drainage tunnel from 8 Mile Road to 12 Mile Road to separate and meter freeway water from the local storm water system to mitigate future flooding concerns.

This $1.4 Billion DBFM project allowed for private financing and the flexibility to fund the project with availability payments spread out over 30 years, enabling MDOT to invest in other projects. This procurement model also requires the concessionaire to maintain the I-75 Segment 3 corridor for 25 years after construction completion, ensuring reliable asset condition.
