The Roaring Fork Safe Passages Prioritization Study provides the scientific foundation for wildlife crossing infrastructure in our valley. Through comprehensive analysis of wildlife-highway interactions along Highways 82 and 133, this study identified where mitigation investments will have the greatest impact for both wildlife and human safety.

Key Findings:

• Wildlife-vehicle collisions are the leading cause of crashes in the Roaring Fork watershed, accounting for 30% of all reported crashes

• Annual collision costs, including wildlife value, exceed $5.2 million

• Six priority corridors were identified where crossing infrastructure can reconnect fragmented habitats and reduce dangerous collisions

The study evaluated locations using wildlife movement patterns, collision data, habitat connectivity, land ownership, and terrain feasibility. This resulted in a tiered approach: Tier 1 priorities where wildlife overpasses and underpasses are most feasible, and Tier 2 priorities where fencing improvements and other strategies will be most effective.

The Priority Areas: The study identified Highway 82 from the Aspen/Pitkin County Airport to Woody Creek as the top priority segment, with additional critical areas at Emma and along Highway 133's Crystal River North corridor. These locations represent our best opportunities to restore migration routes.
