MN: Spring load restrictions end in north-central & north frost zones

The Minnesota Department of Transportation will end spring load restrictions (SLR) in the NORTH-CENTRAL and NORTH frost zones Monday, May 3, 2021 at 12:01 AM. MN: Spring load restrictions end in north-central & north frost zones

Spring Load restrictions have already ended in the other 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

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.
