The Minnesota Department of Transportation (DOT) will end Spring load restrictions in the south and central frost zones, and full-summer overweight permits start in the metro and southeast zones effective Monday, April 26, 2021 at 12:01 a.m.
Spring load restrictions are still in effect in the NORTH-CENTRAL and NORTH frost zones.
Spring Load restrictions have already ended in the METRO and SOUTHEAST 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 at mndot.gov/loadlimits.
Overweight permits for more than 80,000 pound gross vehicle weight continue during spring load restrictions and new overweight 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.
