Mn/DOT to remove spring load restrictions in southern and Metro areas

Restrictions to be lifted on Friday, May 2


ST. PAUL, Minn. - The Minnesota Department of Transportation today announced that spring load restrictions will be removed in the South, Southeastern and Metro frost zones on Friday, May 2 at 12:01 a.m. Spring load restrictions in the Central and North frost zones remain in effect until Saturday, May 10 at 12:01 a.m. Announcements of start and end dates of load increases and restrictions are made with at least three-day notice. Further details regarding spring load restrictions can be found at the Mn/DOT Web site, By phone, call 1-800-723-6543 or 651-747-2253.

The lifting of the spring road restrictions on May 2 affects the following frost zones:

Southeast: Iowa state line north along I-35 (does not include I-35) to Mn19 east to US 61 to US 63 to the Wisconsin state line at Red Wing

South: Iowa state line north to and including US 12 from South Dakota state line to the Wisconsin state line with the exception of the zone noted as the Southeast Zone.

Metro: Anoka, Carver, Chisago, Dakota, Hennepin, Ramsey, Scott and Washington counties

"This year Mn/DOT is using an improved system for determining the end date of spring load restrictions," said Dave Van Deusen, Mn/DOT Pavement Design Engineer. The end date is determined by air temperatures, precipitation and frost depth of the preceding winter. The freezing weather in southern Minnesota this year was mild compared to most years and compared to the northern part of the state. This has improved road strength earlier than some years.

Road preservation
Spring load restrictions help preserve roadways when the pavement is weakened due to partial thaw conditions and trapped water. Mn/DOT estimates the restrictions result in an annual savings of more than $10 million. In Minnesota there are about 39,000 miles of paved roads that should be restricted to lower loads during the spring.
