The Michigan Department of Transportation and local agencies are enacting spring weight restrictions, an annual move the department said is needed to protect roads.

Effective 6 a.m. Monday, March 1, weight restrictions will be imposed and enforced on all state trunkline highways from the Michigan border north to and including M-20 from the interchange with US-31 in Oceana County, then east on M-20 to US-131, then north on US-131 to M-20 in Mecosta County, then east on M-20 to US-10 in Midland County, then east on US-10 to M-25 in Bay City, including the entire Thumb region.

In the restricted areas, the following will apply:

  • On routes designated as "all-season" (designated in green and gold 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.
