ST. PAUL, Minn. – Spring truck weight restrictions on state highways begin March 14 for Minnesota's south, southeast and Metro area frost zones, according to the Minnesota Department of Transportation.
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.
