The Michigan Department of Transportation continues to roll back the weight restrictions on its highways.
Effective 6 a.m. Thursday, March 25, MDOT will lift seasonal weight restrictions on more state roads in the Lower Peninsula.
Weight restrictions will be lifted from the southern Michigan border north to and including M-20 from the interchange with US-31 in Oceana County, 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 area.
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 this line. State routes typically carry M, I, or US designations.
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.
County road commissions and city public works departments put in place their own seasonal weight restrictions, which usually, but not always, coincide with state highway weight restrictions. Signs are generally posted to indicate which routes have weight restrictions in effect.
