Weight restrictions for commercial truck traffic have been imposed and enforced on state roadways from the southern Michigan border north to and including the Mackinac Bridge.
There are no restrictions for legal axle weight loads on roads designated as "all-season trunklines." On routes designated as "seasonal," there will be a posted reduction of 25 percent for rigid pavements and 35 percent for flexible pavements.
All extended permits will be valid for oversized 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 on the restricted routes.
For weight restriction information and updates, call 800-787-8960, or you can access this information on MDOT's Mi Drive Web site at michigan.gov/drive; on "Truckers". All-season routes are designated in green and gold on the MDOT Truck Operators Map, which is available online. You may also sign up to receive e-mail alerts.
