Spring truck weight restrictions begin March 5 for southeast, Twin Cities frost zones; March 6 for south frost zone
ST. PAUL, Minn. – Spring truck weight restrictions on state highways will begin March 5 for Minnesota's southeast and Twin Cities Metro area frost zones, and March 6 for the south frost zone.
Winter load increases and overweight permits remain in place for the state's central, north-central and north 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.
