ST. PAUL, Minn. – Spring truck weight restrictions on state highways begin March 18 for Minnesota's Central frost zone, according to the Minnesota Department of Transportation.
Winter load increases and overweight permits remain in place for the state's North-Central and North frost zones. Spring load restrictions are already in place for the South, Southeast and Metro frost zones.
MnDOT limits truck weights to prevent damage to roads weakened during the spring thaw. Ending dates for spring load restrictions will be established by monitoring roadway strength as weather conditions change.
The Central frost zone extends south from the southern limit of the North-Central Zone (Highways 10, 210, 18, Interstate I-35 and Highway 48 to the Wisconsin state line) to a line following and including Highway 12 from the South Dakota state line to the Hennepin County line.
Road restriction maps showing the locations of weight-restricted routes and state highways open to maximum 10-ton axle weights are listed at www.dot.state.mn.us/materials. Click on "Seasonal Load Limits," and then "Spring Load Restrictions" for the most up-to-date information.
