Effective Wednesday (December 24) at 12:01 a.m., Wisconsin’s frozen road law will expand to include numbered state and federal highways within the area designated by the Wisconsin Department of Transportation (WisDOT) as Zone 2 across much of north central Wisconsin. The frozen road law is already in effect in Zone 1 in far northern Wisconsin. The frozen road determination for other portions of the state will be made once conditions warrant.
The frozen road law allows heavier loads for trucks carrying peeled or unpeeled forest products cut crosswise (not including woodchips), and salt and sand for winter maintenance until approximately early March, unless thawing necessitates an earlier cancellation of the provision or continued cold weather allows for an extension of the declaration period.
The declaration is issued once the ground under highway pavement is frozen to a depth of at least 18-inches, allowing the maximum gross weight for trucks hauling logs or salt and sand for maintaining roads in winter to go up to 98,000 pounds on vehicles with a minimum of five axles (from the normal 80,000 pounds). Special permits for hauling the increased weights will not be required in Zones 1 and 2, however, vehicles must be legally licensed at 80,000 pounds to handle the increased weights. The higher weight limits do not apply to county or local roads unless authorized by the local agency having maintenance authority. Also, higher weights may not be transported on any highways or bridges specifically posted for lower weight limits.
