I-475 corridor project - Genesee County
About the project
The I-475 projects began with a $300 million investment commitment from the Rebuilding Michigan Bond program to reconstruct the remaining eight miles of I-475. As the development process began, MDOT heard the community’s concerns about I-475 and the desire to improve the local facilities as a part of the project. To address these comments and concerns, MDOT initiated a Planning Environmental Linkages (PEL) study.
MDOT has completed the PEL study on eight miles of I-475 from Bristol Road to Carpenter Road. While there is not enough funding in place to implement every concept derived from the PEL, MDOT will not abandon the project. Opportunities to support pedestrian and multi-modal transportation while improving neighborhood connectivity still exist and are being analyzed. Dependent on traffic analysis and ongoing discussion with the city, there is potential to transition existing structures to pedestrian crossings and add shared-use paths adjacent to I-475.
The project will be completed in two sections: the North Section of I-475 from the Flint River to Carpenter Road and the Middle and South Sections of I-475 from the Flint River to Bristol Road.

Middle/South sections: Flint River to Bristol Road
I-475 from the Flint River to Bristol Road
The PEL study provided MDOT with valuable insight of the community’s vision for the corridor. One of the most important components from the PEL study is the need for improved connectivity between the communities on the east and west sides of I-475. As a direct result of the PEL findings, MDOT is looking at each I-475 crossing within the project limits for opportunities to improve connectivity and pedestrian safety between the communities. The opportunities currently being incorporated into the project are:
- Converting the Second Street bridge to a pedestrian-only facility.
- Improved multimodal/pedestrian facilities.
- Removal of redundant entranced/exit ramps.
- Removal of 14th Street bridge.
- Removal of indirect left-turns.
Proposed construction dates: Spring 2026 - Fall 2027
Cost: $270 million
Traffic restrictions: To be announced
Additional information
This work is part of Gov. Gretchen Whitmer’s Rebuilding Michigan program to rebuild the state highways and bridges that are critical to the state's economy and carry the most traffic. The investment strategy is aimed at fixes that result in longer useful lives and improves the condition of the state's infrastructure.
