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. The project will be completed in two sections: the North Section of I-475 from the Flint River to Carpenter Road and the South Section of I-475 from Bristol Road to the Flint River.

Reconstruct I-475 from Flint River to Carpenter Road

MDOT is rebuilding northbound and southbound I-475 from the Flint River to Carpenter Road, including the service drives and the Flint River bridge. Punch list items such as grading and slope restoration will be completed by summer 2026.

Northbound I-475: Spring - Winter 2024
Southbound I-475: Spring - Winter 2025

Cost: $141 million

Traffic restrictions: Northbound traffic will use I-69 to I-75 and local posted detours. Southbound traffic will use I-75 to I-69 and local posted detours.

I-475 from Bristol Road to the Flint River

As a direct result of public feedback, MDOT will continue to study the I-475 bridges and crossings due to a desire for improved connectivity between the communities on the east and west sides of I-475. To fund the additional costs of implementing concepts developed by the planning and environmental linkages (PEL) study, MDOT is seeking additional funding. The following options are being considered:

  • Converting the Second Street bridge to a pedestrian-only facility.
  • Converting select crossings under I-475 to pedestrian-only facilities.
  • Widening sidewalks on each side of select bridge structures to accommodate nonmotorized transportation.
  • Upgrading/replacing/relocating existing pedestrian structures.
  • Service drive lane reductions.
  • I-475 lane reductions.
  • Lane reductions on roads over I-475.

The PEL study has provided MDOT with insight into what the community would like to see as the long-term plan for the corridor. Unfortunately, not all concepts can be implemented concurrently. Some concepts will need to be implemented at a later phase or as separate projects, and as funding is realized.

MDOT will apply any additional funding to the project design and request input from the community on the proposed concepts and alternatives.  

Proposed dates: Spring 2026 to fall 2028.

Cost: $270 million

Traffic restrictions: To be provided at a future date.
