MDOT has been working on the Whitetail Road Project.

The Montana Department of Transportation is making improvements on 10.3 miles of Whitetail Road (S-399) that have caused maintenance issues for years in Jefferson County.

"There are sections of Whitetail Road that have historically been problem areas for Jefferson County," said MDT Engineering Project Manager Shane Watson. "Moisture-sensitive soils consisting mostly of silt and clay make the road difficult to maintain. Moisture from rain and snow causes the soil and the road to deteriorate quickly."

Jefferson County identified Whitetail Road as a high priority roadway. Every year, the county spends a large portion of their road maintenance time and budget to keep Whitetail Road open.

"MDT is removing the soil from the problem areas and replacing it with an improved gravel base," said Watson. "Providing a solid foundation will allow the county to save a lot of time and money maintaining the road in the future."

The project is divided into two segments. The first segment of the project starts near Antelope Lane and extends north on the gravel surface ending approximately a half mile beyond the National Forest boundary. The second segment of the project starts at the intersection of Whitetail and Hot Springs roads and continues north to the Jefferson County Fairgrounds.

The project is expected to be completed in fall 2020. Bjorn Johnson Construction from Missoula is the prime contractor.
