Help Keep the Gallatin Clean & Clear

You can help improve the health of the Gallatin River and ensure that Highway 191 provides safe passage for people, wildlife and fish!

The Montana Department of Transportation (MDT) is developing a “corridor study” of US Highway 191—between Four Corners and Beaver Creek Road south of Big Sky—to address safety, traffic and environmental concerns. Highway 191 borders the Gallatin River and provides many river access sites including MDT pullouts and trailheads. Improvement opportunities related to the health of the Gallatin could include reducing streambank erosion, preventing vehicle pollution from entering the waterways, bettering streambank conditions and ensuring that fish and other aquatic species have a safe passage under the highway. This study is an important opportunity for local communities to get involved and elevate public priorities to shape the future of the corridor. The public comment deadline is August 28th.
