Winter load increases end and spring load restrictions start March 29 in north-central and north zones

Snow-lined roadway with pine trees in the sunshine

The Minnesota Department of Transportation will end winter load increases and start spring load restrictions in the north-central and north zones 12:01 a.m. Wednesday, March 29.

Spring load restrictions are already in effect in the other zones. Seasonal load limit 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 will continue 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 weather is affecting roadway strength.

MnDOT will report start and end dates on its 24-hour automated message center at 1-800-723-6543 for the U.S. and Canada.
