ST. PAUL — With spring weather comes spring truck weight restrictions on state highways.

The restrictions began this week for all of Minnesota as a way for the Minnesota Department of Transportation to limits truck weights and 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.

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.
