SAGINAW COUNTY, Mich. -- The northbound ramp from Interstate 675 onto northbound Interstate 75 is now shut down for repairs and will remain so until late November.

Northbound traffic can exit onto southbound I-75, exit at the Zilwaukee exit (about a mile) and then get back onto northbound I-75.

Anita Richardson, spokeswoman with the Michigan Department of Transportation, said detour signs are posted.

The work is part of a larger multimillion-dollar project to repair sections of I-675 and replace or repair multiple bridges and highway access ramps.
