The Minnesota Department of Transportation will end spring load restrictions (SLR) in the METRO frost zone on Monday, March 18, 2024, at 12:01 AM.
Please check with local agencies before increasing any weights on their routes. The sign erected on the roadway governs the load limit in effect.
Seasonal load limit (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 pounds gross vehicle weight continue during spring load restrictions and new permits will be issued if all axle and group weights are legal.
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 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 the weather is affecting roadway strength.
