| Description | Segment 3 of the Michigan Department of Transportation's (MDOT) I-75 Modernization Project completed the reconstruction and widening of an 18-mile segment 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 in Oakland County from 8 Mile Road to north of 13 Mile Road. This corridor had not received comprehensive improvements since it opened in the 1960s. Segment 3 improvements included complete pavement reconstruction, addition of a HOV lane, replacement of 28 bridges, safety improvements, and ITS upgrades. Additionally, the project included a four-mile storage and drainage tunnel to separate freeway water from the local combined sewer system. The project was delivered through a 30-year design-build-finance-maintain availability payment concession. The concession combined what would have been 5 construction segments under traditional contracting methods into one segment and accelerated the completion date by 12 years. |
