March 3, 20210

The Michigan Department of Transportation (MDOT) and local agencies are enacting spring weight restrictions.

Weight restrictions valid from March 1, on all state trunkline highways from the Michigan border north to and including M-20 from the interchange with U.S. 31 in Oceana County, then east on M-20 to U.S. 131, then north on U.S. 131 to M-20 in Mecosta County, then east on M-20 to U.S. 10 in Midland County, then east on U.S. 10 to M-25 in Bay City.

All state trunklines in this region have weight restrictions enforced and imposed. State routes typically carry M, I or U.S. designations.

Following rules apply on the certain areas:

On routes designated as “all-season” (colored in green and yellow on the MDOT Truck Operators Map), there will be no reduction in legal axle weights
On routes designated as “seasonal” (designated in solid or dashed red on the MDOT Truck Operators Map), there will be a posted weight reduction of 25 percent for rigid (concrete) pavements and 35 percent for flexible (asphalt) pavements
All extended permits will be valid for oversize loads in the weight-restricted area on the restricted routes. Single-trip permits will not be issued for any overweight loads or loads exceeding 14 feet in width, 11 axles and 150 feet in overall length on the restricted routes.
