Check with local agencies (cities, counties and townships) prior to increasing any weights on their routes. The sign erected on the roadway governs the load limit in effect.  A winter weight increase permit is required to take advantage of the 10% weight increase on interstate highways only; a permit is not required for state trunk highways.

MnDOT will report start and end dates on its 24-hour automated message center at 1-800-723-6543 for the U.S. and Canada, and locally at 651-366-5400 for the Minneapolis/St. Paul area.
