Secondary 206 Safety Improvements

Project Overview

SF 119 Slope Flatten S-206

The Montana Department of Transportation is designing safety improvements to Secondary 206 (S 206) between Kalispell and Columbia Falls in Flathead County. The project begins about a quarter-mile north of the Montana Highway 35 (MT 35) junction and extends north a little over 9 miles, ending about a quarter-mile south of the US 2 junction near Columbia Falls.

Proposed improvements include:

  • Widening the shoulders to 4 ft.
  • Flattening the steep slopes on the sides of the road.
  • Installing guardrail.
  • Adding new mailbox turnouts.
  • Resurfacing and chip sealing the roadway.
  • Installing centerline and shoulder rumble strips.
