Spring load restrictions will end Monday, April 20, at 12:01 a.m. on unrestricted state highways in the south frost zones, according to the Minnesota Department of Transportation.

Spring load restrictions have already ended in the southeast and metro frost zones. Spring load restrictions are still in effect in the central, north-central and north frost zones.

Overweight permits for more than 80,000 pound gross vehicle weight will continue during spring load restrictions and new permits will be issued if all axle and group weights are legal.

The start and end dates for spring load restrictions are variable and based on how weather is affecting roadway strength. All changes are made with a minimum three-day notice.
