Spring truck weight restrictions on state highways will begin Friday, March 15th 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. MnDOT limits truck weights to prevent damage to roads weakened during the spring thaw.
