MANKATO -- Motorists may encounter brief delays as crews install rumble stripes on area highways in June and July.

The following highways in LeSueur, Nicollet and Sibley counties will be marked with centerline and edge line rumble stripes beginning June 6:
· Highway 13 - Montgomery to New Prague
· Highway 19 - Winthrop to Gaylord
· Highway 60 - Highway14 to Waterville, except Madison Lake and Elysian
· Highway 99 – St. Peter to Highway 13, except Cleveland and Le Center

The following highways in Blue Earth, Brown, Cottonwood and Nobles counties will be marked with centerline and edge line rumble stripes beginning July 18:
· Highway 15 - Three locations from New Ulm to the Nicollet/Sibley county line
· Highway 59 - Worthington to the Nobles/Murray county line
· Highway 68 - Highway 15 to near Mankato
· Highway 71 - Highway 30 to Sanborn

Flagging operations will control traffic on two-lane highway to guide motorists through the work zones.

MnDOT places rumble stripes on highway centerlines and edgelines 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.
