Winter Load Increases in the North-Central and North Frost Zones ended at midnight on Tuesday, March 19 and Spring Load Restrictions are now in effect in those two zones, the Minnesota Department of Public Safety and Polk County Highway Department report.
Winter Load Increases in the South, Southeast, Metro and Central Frost Zones have already ended and Spring Load Restrictions took effect March 15.
Road Restriction maps indicating the locations of weight restricted routes are on the MnDOT Seasonal Load Limits website at mndot.gov/loadlimits.
Overweight Permits for over 80,000-pound 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.
For questions about enforcement call the Minnesota Department of Public Safety - State Patrol - Commercial Vehicle Enforcement, at 651-350-2000.
Load limit dates are based on how weather is affecting roadway strength. These dates are established by monitoring roadway strength as weather conditions change. Therefore, these dates are variable. The end of Winter Load Increases and start of Spring Load Restrictions are separate events which may not occur on the same date.
