Spring truck load restrictions end April 20 for south frost zones

ST. PAUL, Minn. – 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. The frost zones and restricted routes can be found on the MnDOT load limits map.
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.

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 will 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.  For questions about over legal weight/size “heavy haul” trucking, call MnDOT’s Freight and Commercial Vehicle Operations - Oversize/Weight Permits, 651-296-6000 or email: ofcvopermits.dot@state.mn.us.
