Date: March 17, 2022
The Minnesota Department of Transportation will start spring load restrictions in the NORTH-CENTRAL and NORTH zones Monday, March 21, 2022 at 12:01 AM.
Spring load restrictions are already in effect in the SOUTH, SOUTHEAST and METRO zones.
Winter load increases have already ended in the CENTRAL zone.
As announced in the March 14 memo, spring load restrictions will start in the CENTRAL zone Friday, March 18 and winter load increases will end in the NORTH-CENTRAL and NORTH zones Saturday, March 19.
Seasonal load limit zones and restricted routes can be found on the MnDOT load limits map.
Start and end dates and other load limit information are shown at mndot.gov/loadlimits.
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.
