MADISON - Warmer temperatures mean frozen road law coming to an end - Spring Thaw and Class II road restrictions to be implemented
Changes take effect Saturday in Zones 3, 4 and 5 (southern half of
Wisconsin), and on Monday in Zones 1 and 2 (northern half of the state)
Due to predicted warmer weather, the Wisconsin Department of
Transportation (WisDOT) is announcing the frozen road declaration will
end soon - along with implementation of Spring Thaw and Class II road
restrictions. The changes take effect Saturday, February 18, 2017 at
12:01 a.m. in Zones 3, 4 and 5 (roughly the southern half of the state)
and on Monday, February 20th at 12:01 a.m. in Zones 1 and 2 (northern
half of Wisconsin).
Class II roads include about 1,400 miles of state highways susceptible
to damage from heavy trucks during the spring thaw period as frost
leaves the ground. More information regarding Class II roadways and
roadway postings can be found on WisDOT's website<http://wisconsindot.gov/Pages/dmv/com-drv-vehs/mtr-car-trkr/ssnl-wt-rsrctns/default.aspx> by looking under "Weight Restriction Programs."
* Declaration of Spring Thaw also means suspension of most divisible
load overweight permits including permit numbers beginning with any of
the following two-letter codes: AC, AG, FF, MI, PB and RF.
* Non-divisible load permit restriction: The following permit types
are not valid on Class II Highways during spring thaw and may not exceed
posted weight on any road or bridge: AA, AP, BH, GG, II, MH, MP, SA,
SM, SS and ST. Transportation of liquid milk products under
non-divisible permit type AA is also suspended.
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. More information on overweight permits can be found on the
by searching under "oversize overweight permits."

questions can contact WisDOT's Oversize/Overweight Permits Unit at

restrictions is available by calling (608) 266-8417.
