M-46 improvements begin July 21 in Tuscola, Sanilac counties

SAGINAW, Mich. - The Michigan Department of Transportation (MDOT) is investing approximately $3 million to improve more than 14 miles of M-46 from M-24 (Mertz Road) to M-53 (Van Dyke Road) in Tuscola and Sanilac counties. Work includes cape seal, micro cold milling, joint repairs, shoulder gravel, sidewalk ramps and pavement markings.

"Across Michigan, we are moving dirt and fixing the damn roads to grow our economy, helping Michiganders go to work, drop their kids off at school and run errands safely," said Gov. Gretchen Whitmer. "By the end of this construction season, we will have fixed, repaired or replaced nearly 24,500 lane miles of roads and 1,900 bridges, supporting thousands of good-paying, local jobs without raising taxes by a dime. This year, let's build on our momentum to pass a bipartisan local road funding plan so we can keep fixing our damn roads and creating good-paying, local jobs."
