North Shore listening to rumble strips

Last week the Minnesota Department of Transportation hosted a “Listening Session” to provide information on the installation of side-shoulder rumble strips on Highway 61. Attendees gathered at Tettagouche State Park and visited some nearby locations to listen to rumble strips versus mumble strips.
 
To follow up on that meeting, WTIP’s Rhonda Silence spoke with Assistant District Traffic Engineer Morrie Luke.
 
During that conversation, Luke spoke about three videos recorded by MnDOT of cars traveling on a highway. One simply driving along a paved road; another crossing over a sinusoidal rumble strip—sometimes called a mumble strip. And finally, MnDOT made a video of a vehicle driving over a rectangular, or standard, rumble strip. Click below to see and hear those videos.
