Winter load increases will end, and spring load restrictions begin in the North-Central and North frost zone Monday, March 8 at 12:01 a.m. Frost zones and restricted routes can be found on the MnDOT load limits map.
Overweight permits for more than 80,000-pound gross vehicle weight will continue and new permits will be issued if all axle and group weights are legal (axle weight limits).
Full-summer overweight permits can be issued, during the spring load restriction period, for travel on the interstate system only.
Middle-range overweight permits become available within each frost zone when spring load restrictions are lifted. Full-summer overweight permits become available two to three weeks after spring load restrictions are lifted.
Ending dates for spring load restrictions are variable and based on how the weather is affecting roadway strength.
