Effective at noon on April 2, the Michigan Department of Transportation (MDOT) will lift spring weight restrictions on state roads from the southern Michigan border north to the Mackinac Bridge.
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 Mackinac Bridge. State routes typically carry M, I, or US designations.
On March 16, Gov. Gretchen Whitmer signed Executive Order 2020-12, temporarily lifting seasonal weight and other delivery-related restrictions for vehicles on state and local roads carrying essential supplies to mitigate the spread of Novel Coronavirus (COVID-19). The executive order extends until 11:59 p.m. Monday, April 13. This spring weight restriction update does not alter the direction given in the governor's order. Permits will still be required for loads exceeding the normal legal limits.
