MADISON — The Wisconsin Department of Transportation (WisDOT) is installing centerline and shoulder rumble strips this summer on over 500 miles of rural, two-lane state highways. It’s an effort to help prevent highway run-off crashes and enhance overall public safety.

Right now, rumble strips are installed along Interstate highways and other divided highways. They provide an audible and vibratory warning to motorists who drift from their travel lane. 

Beginning in mid-August, WisDOT will oversee installation of retrofit rumble strips by grinding them into about 500 miles of centerline and about 50 miles of shoulder pavement along identified two-lane rural state highway segments.  The work is expected to be completed this fall at an estimated cost of $3.5 million. 

National research shows that adding shoulder rumble strips can reduce death or injury from single-vehicle highway run-off crashes by 29 percent, while center line rumbles reduce head-on and side-swipe crashes by 44 percent.
