Spring truck weight restrictions begin next week in all state frost zones
Legal truck weight limits that were increased during the winter months in Minnesota will end next week. Spring weight restrictions will begin at the same time, the Minnesota Department of Transportation announced.
Spring truck weight restrictions begin in the south, southeast and Twin Cities Metro frost zones at 12:01 a.m. on Monday, March 8. Spring weight restrictions in the central, north-central and north frost zones begin at 12:01 a.m. on Tuesday, March 9.
No overweight truck permits are issued during the spring load restriction period.
Frost zone boundaries are:
- South: Iowa border north to Hwy 12 and from the Dakota County border east to the Hennepin County line, along the Carver and Scott county lines to I-35, south to the Iowa border. (This zone includes Hwy 19 along the Scott County border.)
- Southeast: Iowa border north along I-35 (does not include I-35) to the Scott County line, east along the Dakota County line, including Hwy 19 to the Wisconsin border.
- Twin Cities Metropolitan area: Anoka, Carver, Chisago, Dakota, Hennepin, Ramsey, Scott and Washington counties. (This zone does not include Hwy 19 along the southern border of Scott County.)
- Central: Southern limit of the north-central zone (Hwy 10, Hwy 210, Hwy 18, I-35, Hwy 48) to a line following and including Hwy 12 from the South Dakota border to the Hennepin County line.
- North-Central: Southern limit of the north zone to a line following U.S. Hwy 10 from the North Dakota border east to Motley, Hwy 210 east to Brainerd, Hwy 18 east to I-35, I-35 south to Hwy 48 and then Hwy 48 east to the Wisconsin border.
- North: South from the Canadian border to a line following Hwy 1, Hwy 89, Hwy 2 and Hwy 33 and I-35 at the Carlton-St. Louis county line and then south to the Wisconsin border.
“Truck weight restrictions are used in the spring to help preserve pavements that lose strength due to partial thaw conditions and trapped water,” said Keith Shannon, director of Mn/DOT’s Office of Materials. “The ending date for spring load restrictions is dependent on weather condition changes and cannot exceed eight weeks."
