The Minnesota Department of Transportation will end spring load restrictions (SLR) in the SOUTHEAST and METRO frost zones on Monday, April 12 at 12:01 AM.
Spring load restrictions are still in effect in the SOUTH, CENTRAL, NORTH-CENTRAL and NORTH frost zones.
Frost zones and restricted routes can be found on the MnDOT load limits map.
Start and end dates and other load limit information are shown here.
Overweight permits for more than 80,000 pound gross vehicle weight continue during spring load restrictions 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.
