Mn/DOT ends spring weight restrictions in 3 frost zones

ST. PAUL, Minn.—The Minnesota Department of Transportation will lift seasonal weight restrictions for trucks in three frost zones at 12:01 a.m. on April 22. The zones affected are the southern, southeastern and Twin Cities metropolitan area frost zones.

Seasonal weight limits remain in effect for the central, north central and northern frost zones.

Mn/DOT ends seasonal weight limits when it determines that state highways have regained their full load-bearing capacity that is diminished by moisture during early spring thawing conditions.

     The affected zone boundaries are:

  • Southeast: Iowa border north along Interstate-35 (does not include I-35) to the Scott County line, east along the Dakota County line, including Hwy 19 to the Wisconsin border.
  • South: Iowa border north to Hwy 12 and from the South Dakota 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.)
  • Twin Cities metropolitan area: Anoka, Carver, Chisago, Dakota, Hennepin, Ramsey, Scott and Washington counties. (This zone does not include Hwy 19 along Scott County’s southern border.)  

 “Mn/DOT monitors weather and road conditions daily; truckers should check frequently to determine precisely when changes occur in the state’s frost zones,” said Keith Shannon, director of Mn/DOT’s Office of Materials.
He said  Mn/DOT urges truckers to check the department’s seasonal load limits Web site to learn the location of weight-restricted routes, changing road conditions and state highways open to 10-ton axle loads. The address is www.mrr.dot.state.mn.us . The information is also available toll-free by calling 1-800/723-6543 in the U. S. and Canada or by calling 651/747-2253 in the Twin Cities metro area.
