Rumble stripe projects in southern Minnesota begin Aug. 31


MANKATO, Minn. - Motorists traveling in southern Minnesota may encounter brief delays beginning Aug. 31 as crews install rumble stripes on area highways in Blue Earth, Brown, Cottonwood and Nobles:


Flagging operations will control traffic on two-lane highways to guide motorists through the work zones.  The project is expected to be completed by late September.


MnDOT places rumble stripes on Hwy centerlines and edge lines as a safety and cost-saving measure. They warn motorists who leave the traveled lane, which prevents road-departure crashes. The paint is much more visible in rainy and wet conditions, and the lifespan of the painted markings extends due to reduced damage from snowplows.


Motorists should drive with extreme caution through the work zones and watch for workers and equipment.

Minnesota traffic safety efforts are components of Toward Zero Deaths (TZD), the state’s primary road safety initiative.  A primary vision of the TZD program is to create a safe driving culture in Minnesota in which motorists support a goal of zero road fatalities by practicing and promoting safe and smart driving behavior. TZD focuses on the application of four strategic areas to reduce crashes — education, enforcement, engineering and emergency trauma response.
