Winter truck load increases ended and spring load restrictions began at 12:01 a.m. on Friday, March 13, on unrestricted state highways in the north and north central frost zones, according to the Minnesota Department of Transportation. The frost zones and restricted routes can be found on the MnDOT load limits map.
Spring load restrictions have already begun in the other frost zones. 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 weather is affecting roadway strength.
