Frozen road declaration ending in Wisconsin
Forecasts for warming weather throughout the state have prompted the Wisconsin Department of Transportation (WisDOT) to announce that the frozen road declaration will end and spring thaw requirements will be in effect on all state highways effective at 12:01 a.m. on Monday, March 9.
State-maintained highways were declared frozen statewide on Dec. 22, 2008, allowing trucks hauling specific types of forest products (peeled or unpeeled forest products cut crosswise, not including woodchips), or salt and/or sand to carry heavier loads.
A map depicting where and when the frozen road and spring thaw declarations are effective and where state highways are posted is available on the Wisconsin Department of Transportation's Web site, as well as information on overweight permits.
Up-to-date information on the spring thaw period is also available by calling (608) 266-8417.
The transition period when roadbeds change from a frozen condition until the time when sub-grades under the roadway dry out and firm up is when heavy loads pose the greatest threat to highways. The spring thaw weight restriction means divisible load permits, such as for pulpwood hauling or garbage transport, are suspended on all state highways. Use of other state-issued, non-divisible, single trip permits is restricted on Class II state highway sections.
In addition, some sections of Class II state highways will be posted for less than the legal weight limit during this same period. Refer to the WisDOT Web site for current information on state posted roads.
Local county highways, town roads, and city and village streets may also be posted or limited to legal load limits or less. Decisions to place or lift weight restrictions on those roads are up to local units of government.
