Spring truck weight restrictions on state highways began March 15 for Minnesota's south, southeast and Twin Cities Metro area frost zones.
Winter load increases and overweight permits remain in place for the state's central, north-central and north frost zones.
In addition, the Houston County Highway Dept. announced weight restrictions for its roadways as well as town roads and city streets. Any roadway not posted in the county has a weight limit on any single axle that shall not exceed 5 tons on an unpaved street or highway and 10 tons on a paved street or highway, any single axle. (M.S. 169.87).
MnDOT and government officials limit truck weights to prevent damage to roads weakened during the spring thaw.
