March 7, 2017 -- Effective one half-hour before sunrise on Wednesday, March 8, weight restrictions will be lifted from the southern Michigan border north to and including US-12 at the Michigan/Indiana border east to I-94 in Berrien County, then north and east to I-69 in Calhoun County, then north on I-69 to Lansing and continuing on I-69 east to Port Huron, St. Clair County.

Frost restrictions are still in effect for the remainder of the state and will be imposed and enforced on all state trunkline highways north of the US-12, I-94, I-69 lines. State routes typically carry M, I, or US designations.

In the restricted areas, the following will apply:

  • On routes designated as "all-season routes" (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      pavements and 35 percent for flexible 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.
