Winter load increases end for south, southeast, metro and central frost zones; spring load restrictions start for south, southeast and metro frost zones
ST. PAUL, Minn. — The Minnesota Department of Transportation will end winter load increases in the south, southeast, metro and central frost zones Thursday, March 14.
Spring load restrictions will start Friday, March 15 in the south, southeast and metro frost zones.
The frost zones can be found on the MnDOT load limits map.
Road restriction maps showing locations of weight-restricted routes are listed at mndot.gov/loadlimits. Click on Spring Load Restrictions and then any of the mapping options.
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. See axle weight limits.
Full-summer overweight permits can be issued during the spring load restriction period when engaging in interstate through movement travel only (no starting or stopping off the interstate system).
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.
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, and locally at 651-366-5400 for the Minneapolis/St. Paul area.
The use of load restrictions save taxpayers $14 million per year in preventive damage to pavements. See research.
