Spring weight restrictions expanding to all state roads Monday

March 16, 2018 — The Michigan Department of Transportation (MDOT) and local agencies are enacting additional annual spring weight restrictions to protect roads.

Effective at 6 a.m. Monday, March 19, weight restrictions will be expanded to cover all state trunkline highways for the entire state of Michigan, both Upper and Lower peninsulas. 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.

For weight restriction information and updates, call 800-787-8960, or you can access this information on MDOT’s website at www.michigan.gov/truckers, under “Restrictions.” All-season routes are designated in green and gold on the MDOT Truck Operators Map, which is available online. You also may sign up to receive e-mail alerts.
