Secondary 206 Safety Improvements
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.
