Overweight permits

Permits for over 80,000 GVW will continue and new permits will be issued if all axle and group weights are legal. Existing middle-range and full-summer overweight permits end when Winter Load Increases are removed. No middle-range or full-summer overweight permits are issued during the Spring Load Restriction period. Middle-range overweight permits become available within each frost zone when Spring Load Restrictions are lifted. Full-summer overweight permits become available within each frost zone starting two to three weeks after Spring Load Restrictions are lifted.

The ending dates for Spring Load Restrictions are based on how weather is affecting roadway strength. These dates are established by monitoring roadway strength as weather conditions change. Therefore, the ending dates for Spring Load Restrictions are variable.

As soon as a date is set, MnDOT will report this date on its 24-hour automated message center at 1-800-723-6543 for the USA and Canada, and locally at 651-366-5400 for the Minneapolis/St Paul area. This information is also published on the MnDOT Seasonal Load Limits website www.dot.state.mn.us/materials.
