Starting Monday, July 27th, the Department of Transportation will begin work on the Old MT 200 Erosion Repair project.
Construction will take place between East Missoula and Bonner, addressing about a quarter mile of roadway along the Clark Fork River near Marshall Canyon Road.
MDT said the river experienced heavy runoff in 2019, causing significant erosion between the river and Old MT 200.
The project will shore up the roadway and prevent further damage by replacing the existing stabilizing structure with a new erosion prevention structure. They’ll also replace some parts of the road as well.
The project will cost $4.6 million, funded entirely by federal emergency relief funds.
Until November, travelers can expect single-lane closures and delays of up to 20 minutes.
MDT is recommending that you avoid the area and use alternative routes if you can, but they will have a smart signal to monitor traffic for those who use the road during the construction period.
