MDOT weight limits start

LANSING, Mich.– The Michigan Department of Transportation and local agencies continue to adjust annual spring weight restriction areas to protect roads.

Effective 6 a.m. today, weight restrictions will be imposed and enforced on all state trunklines in the Upper Peninsula. 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% for rigid (concrete) pavements and 35% 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.
