Hwy 61 centerline rumble strip filling project begins in late-July in Cook, Lake County

DULUTH, Minn. — Motorists may encounter temporary, single lane closures in Cook and Lake County when a centerline rumble strip filling project begins either Monday, July 28 or Tuesday, July 29. The work is expected to take about one month to complete.

The centerline rumble strips are being filled because they created higher than expected noise levels in populated areas along the North Shore.

MnDOT is reviewing its centerline rumble strip policy, including criteria on where centerline rumble strips should be/should not be installed and is researching the effectiveness of alternative rumble strip designs that maintain safety measures for drivers while reducing the noise impact to the surrounding areas.  

MnDOT urges motorists to always be attentive, drive with caution, slowdown in work zones and never enter a road blocked with barriers or cones.
