Spring truck weight restrictions begin March 12 for north-central frost zone; March 13 for north frost zone
ST. PAUL, Minn. - Spring truck weight restrictions on state highways will begin March 12 for Minnesota's north-central frost zone and March 13 for the north frost zone. Spring weight restrictions are already in place for the south, southeast, central and Twin Cities Metro area frost zones.
MnDOT limits truck weights to prevent damage to roads weakened during the spring thaw.
Spring load restriction dates and the six frost zones in Minnesota are listed on MnDOT’s website at www.mrr.dot.state.mn.us. Click on "Seasonal Load Limits," then click on "Spring Load Restrictions" for the most up-to-date information.
The information also is available toll-free by calling 1-800-723-6543 in the United States and Canada or by calling 651-366-5400 in the Twin Cities Metro area.
Ending dates for spring load restrictions are established by monitoring roadway strength as weather conditions change. All changes are made with a minimal three-day notice.
Travelers in Minnesota can get up-to-date information on road conditions, construction and weather reports from MnDOT's 511 traveler information service. Dial 5-1-1 or visit www.511mn.org.
