Orange barrels on a highway

“Mumble strip” installation begins May 31 on west central Minnesota highways

DETROIT LAKES, Minn. – Motorists on several west central Minnesota highways will soon encounter a quieter form of rumble strips on the roadway.

Crews will begin installing sinusoidal centerline rumble strips, or “mumble strips,” on 13 highways starting May 31.

The mumble strips alert drivers if they drift out of their lane similar to traditional rumble strips, but their design reduces the amount of noise heard outside of the vehicle.

The sections of highways receiving mumble strips include:

  • Highway 9 from Highway 10 to Felton
  • Highway 9 from Benson to Highway 104
  • Highway 28 from Morris to Glenwood
  • Highway 29 from Starbuck to Benson
  • Highway 32 from Ulen to the Norman County line
  • Highway 55 from Barrett to the Douglas County line
  • Highway 55 from Glenwood to the Stearns County line
  • Highway 59 from Interstate 94 to Detroit Lakes
  • Highway 87 from Frazee to the Wadena County line
  • Highway 108 from Pelican Rapids to near Dent
  • Highway 113 from west of Elbow Lake Village to the Hubbard County line
  • Highway 114 from Highway 55 to Starbuck
  • Highway 200 from Mahnomen to the Norman County line

Motorists may encounter brief delays while crews install the mumble strips.

This is the Minnesota Department of Transportation’s first sinusoidal centerline rumble strip project in west central Minnesota.

AAA Striping Service of St. Michael is the prime contractor on the $800,000 project.

The work is expected to take about one month.

Rumble and mumble strips are installed as low-cost safety measure to reduce crashes in which cars run off the road or across the center line.
