As of May 16, 2023:
Thank you for your understanding and patience! US 93 Rumble Strip roadwork is finished.
The Montana Department of Transportation (MDT) in partnership with HighMark Traffic Services Inc. announces completion of the roadwork project on US Highway 93 (US 93) between the Interstate 90 (I 90) Wye Interchange and Big Arm. Rumble strips were added to portions of US 93 south of Evaro near the BuckSnort Steakhouse; north of Ashley River Road to just south of Timberlane Road between St. Ignatius and Ronan; and north of Polson from Wilderness Valley Road toward Melita Island Road.
All construction took place at night to reduce traffic delays.
The goal of this project was to install rumble strips on US 93. Rumble Strips help to reduce roadway departure crashes. They are a low-cost, high impact safety measure that also serve as a guideline to vehicles in low-visibility winter months.
Short safety projects like this keep Montana roadways safe and in good condition over time.

The Montana Department of Transportation (MDT) announces a roadwork project on US Highway 93 (US 93) between the Wye intersection and Big Arm. Rumble strips will be added to portions of the roadway along the highway, including near the BuckSnort Steakhouse south of Evaro. In addition, from north of Ashley Lake Road to just south of Timberlane Road between St. Ignatius and Ronan. Lastly, north of Polson from Wilderness Valley Road toward Melita Island Road. This work will take approximately six weeks. All construction will take place at night to reduce traffic delays. Throughout construction, traffic will be reduced to one lane in areas, using flaggers and lights to direct traffic. Updates will be provided as construction approaches.
Crews will install shoulder rumble strips on both sides of the highway in work zone areas to reduce roadway departure crashes. Rumble strips are grooves in the pavement that produce a rumbling noise and vibration when a driver goes over the strip. The purpose of rumble strips is to alert drivers that they are drifting from their driving lane. They are effective in lowering the number of highway fatalities and provide immediate feedback to drivers when crossing the center or shoulder line. In addition, rumble strips are a low-cost, high impact safety measure that also serve as a guideline to vehicles in low-visibility winter months.
