Winter Load Increases end and Spring Load Restrictions begin on Mar. 9 in the North Frost Zone

North Frost Zone restrictions begin a day after the North-Central Frost Zone

ST. PAUL, Minn. – The ENDING DATE for Winter Load Increases and STARTING DATE for Spring Load Restrictions in the NORTH FROST ZONE will be Wednesday, March 9 at 12:01 AM.

Spring Load Restrictions have already begun in the SOUTH, SOUTHEAST, METRO and CENTRAL FROST ZONES.

Spring Load Restrictions have already been announced for the NORTH-CENTRAL FROST ZONE beginning Tuesday, March 8.

Road Restriction maps indicating the locations of weight restricted routes and those state highways open to maximum ten-ton axle weights are listed on the MnDOT Seasonal Load Limits website at www.mndot.gov/loadlimits . Click on “Seasonal Load Limits,” then click on “Spring Load Restrictions (SLR).” Also available is a text list of the restricted segments along with exceptions to the map.


Permits for over 80,000 lb Gross Vehicle Weight will continue and new permits will be issued if all axle and group weights are legal. 

Up to full-summer overweight permits can be issued during the Spring Load Restriction period only on interstate through movements.

Middle-range overweight permits become available within each frost zone when Spring Load Restrictions are lifted.

Full-summer overweight permits become available within each frost zone starting two to three weeks after Spring Load Restrictions are lifted.

This information is also published on the MnDOT Seasonal Load Limits website: www.dot.state.mn.us/materials.
