I-75 Modernisation Project, US

Oakland Corridor Partners, a John Laing-led consortium, is responsible for the modernisation of an 18-mile stretch of the I-75 in Michigan, USA. Oakland Corridor Partners reached financial close on the project in November 2018. Construction commenced in the autumn of 2019 and is expected to complete in the second half of 2023.

Highlights of the project

The project involves the modernisation of Segment 3 of the I-75, covering a 5.5-mile stretch of road in Oakland County from 8 Mile Road to north of 13 Mile Road. It includes the reconstruction of this corridor, improvements to 28 bridges, safety upgrades across the corridor, and construction of a new four-mile,15-foot diameter storage and drainage tunnel.

This crucial corridor has not received comprehensive improvements since it was built in the 1960s. Drivers will benefit from a safer, less congested route which is less prone to flooding. The public-private partnership model will accelerate completion of the upgrade by up to 12 years versus the Michigan Department of Transport’s original modernisation plan.
