Two local projects overseen by the Michigan Department of Transportation have begun. In Ontonagon County, work on the M-64 bridge over Floodwood River and M-64 bridge over Halfway Creek are underway as part of the $4.9 million MDOT investment to rebuild four bridges in Iron and Ontonagon counties. Work is estimated to finish up in late October. One alternating lane will be open at the bridges during work using temporary traffic signals. A 13-foot width restriction will be in place at the bridges.
