MADISON -- The Wisconsin Department of Transportation (WisDOT) is implementing use of temporary portable rumble strips on a dozen state highway improvement projects scheduled for this construction season. It's part of an effort to enhance the safety of highway workers and motorists.
The rumble strips provide an audible and vibratory warning to motorists entering a construction zone and have helped to reduce speeds and crashes in work zones in other states. They will be used on days when flaggers are working along roadways directing traffic. Signs will alert motorists of the upcoming work zone and installation of the temporary rumble strips. Typically, six rumble strips are placed at each end of the work zone.
2016 state highway construction projects expected to utilize temporary, portable rumble strips during flagging operations include:
Last year, Wisconsin recorded 2,404 work zone crashes that resulted in 945 injuries and 12 fatalities.
