SR 37 along Lake Koocanusa will be undergoing construction between Sutton Creek Rd. (map 20) to Rexford (map 21). Rehabilitation work includes milling the existing road surface and placing a new plant mix overlay surface. Additional work includes new signage, pavement markings, guardrail and rumble strips. The project is intended to preserve and extend the life of the roadway while
reducing maintenance costs. Traffic control will be in place and includes reduced speeds and single-lane traffic. Travelers should expect 10- to 15-minute delays and cycling on a gravel surface through the project area. Work will continue until November 2024, and then will resume June 2025. Consider riding the West Side Alternate to avoid some of the construction.
