I-75 Modernization Project Segment 3

Close

Segment 3 of the Michigan Department of Transportation's (MDOT) I-75 Modernization Project will complete the reconstruction and widening of I-75 from M-102 (8 Mile Road) to south of M-59 in Metro Detroit. Segment 3 is a 5.5-mile segment located north of 8 Mile Road to north of 13 Mile Road in the Cities of Hazel Park, Royal Oak, and Madison Heights, Oakland County. The full project's 18-mile corridor has not received comprehensive improvements since it opened in the 1960s. The need for increased capacity to relieve congestion has been driven by growth along the corridor from land use changes and migration of people, services, and industry. It is an important commercial, commuter, tourist, and local area business route moving people and goods across the state daily. 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). Also included is a safety upgrade that separates traffic entering northbound I-75 from I-696, and northbound I-75 traffic exiting at 11 Mile Road. The project will widen a portion of the segment with the addition of an HOV/general purpose lane in both directions from the 8 Mile Road to 12 Mile Road. 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 system to mitigate future flooding concerns. The project will be delivered through a 30-year design-build-finance-maintain availability payment concession that combines what would have been 5 construction segments under design-bid-build and traditional finance methods into one segment, and accelerates the completion date by 12 years. Segment 1, the northernmost portion from north of Coolidge Highway in Troy to north of South Blvd. in Auburn Hills was completed through design-bid-build contract delivery. Segment 2, the middle section from north of 13 Mile Road in Madison Heights to north of Coolidge Highway is being delivered through design-build contract delivery. The design-build contract was awarded in summer 2018 and construction will be complete in 2020.
