LANSING, Mich. – Effective 6 a.m. Monday, April 15, the Michigan Department of Transportation (MDOT) will lift seasonal weight restrictions on all state trunkline highways in the entire state of Michigan. State routes typically carry M, I, or US designations.
Weight restrictions are implemented during the spring frost thaw period and are now completed for the 2024 season.
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.
Trucking companies located in New Jersey and Canada can obtain information by calling 517-373-6256.
