ST. PAUL -- Winter load increases on state highways in southeastern Minnesota will take effect Jan. 1.
State law allows a 10 percent weight increase on all highways and on nine-ton county roads in designated frost zones. However, a winter weight increase permit is required for interstate routes, according to a Minnesota Department of Transportation news release.
New frost zone boundaries went into effect this season to better accommodate the varying climate in Minnesota's regions.
