Starting Mar. 1, the eight-lane Zilwaukee Bridge on Interstate 75 near Saginaw, MI, is to be closed for at least one month to replace the bridge's expansion joints. Drivers will be detoured to I-675 during the shutdown.

The bridge, which spans the Saginaw River between Saginaw and Bay City, handles about 51,000 vehicles a day. About 30,000 vehicles travel on the four lanes of I-675 in that area each day, according to a published report. The project could keep the bridge closed until just before Memorial Day.
