GENESEE COUNTY — Work is scheduled to begin on the $44 million reconstruction of I-475 starting March 11.
According to the Michigan Department of Transportation, the state will conduct substantial repairs to the 18 miles of I-475 in Genesee County with the work continuing through entire 2019 construction season.
The project will include: rebuilding three 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.
Removal of the pedestrian bridges on each side of the Saginaw Street interchange.
Bridge and ramp work at Saginaw Street and Detroit Street.
The project is expected to be completed in November.
Beginning March 11, northbound I-475 will be reduced to one lane from Carpenter Road to Clio Road. Lane closures will also be in place on Saginaw Street and Detroit Street under I-475. Southbound I-475 will be closed and detoured from the north junction of the I-475 interchange to I-69. Motorists should follow the posted detour using southbound I-75 to eastbound I-69.
Motorists can also expect intermittent single-lane closures in both direction of I-475 from I-69 to the south I-75/I-475 junction for sign upgrades.
MDOT said this work will improve the road surface and drainage, while also improving safety with new signs and freeway lighting. — G.G.
