ESTIMATED COMPLETION DATE:
The Michigan Department of Transportation (MDOT) will invest $44 million in substantial repairs to nearly 18 miles of I-475 in Genesee County. In preparation of the work, crews will begin pavement repairs, including patching and resurfacing within the project limits, and repairs to the sound wall. This work will require single-lane and shoulder closures. The following work is planned within the project limits beginning in spring 2019:
- Rebuilding 3 miles of I-475 from Carpenter Road, north to just east of Clio Road.
- Northbound I-475 will include a 50-year pavement design, using hot mix asphalt.
- I-475 will undergo a capital preventive maintenance cape seal from Clio Road to I-75.
- Interchange improvements and redesign at Saginaw Street, including the removal of two loop ramps.
- A freeway road diet, reducing I-475 from three lanes to two lanes from Saginaw to Carpenter Road.
- Lighting improvements from Carpenter Road to Saginaw.
- Sign improvements along the entire length of I-475.
- The ramps from southbound I-475 to westbound I-69 and from westbound I-69 to northbound I-475 will be resurfaced to accommodate additional traffic during construction.
- Removal of the pedestrian bridges on each side of the Saginaw Street interchange.
- Bridge and ramp work at Saginaw Street and Detroit Street.

Beginning Aug. 27, lane and shoulder closures can be expected as crews work to begin staging the project limits for construction in spring 2019. The ramps at I-69 will be closed and detoured for up to five days during resurfacing in late fall (specific dates will be shared as they become available).
This work will improve the road surface and drainage, while also improving safety with new signs and freeway lighting.
