Wyoming Wildlife Crossings Expected to Reduce Collisions by up to 90%

Why It Matters

Reducing wildlife‑vehicle collisions enhances driver safety, lowers billions in economic losses, and preserves critical habitat corridors, offering a replicable model for transportation agencies nationwide.

Key Takeaways

• Seven underpasses, one overpass, upgraded fencing on US‑189.
• Expected 80‑90% drop in wildlife‑vehicle collisions.
• Project funded $38 million from federal, state, partners.
• Three phases Sep 2025‑Oct 2027, up to 20‑minute delays.
• Wyoming sees 6,000 big‑game collisions costing $20‑23 M annually.

Pulse Analysis

Across the United States, wildlife crossings have transitioned from niche engineering solutions to mainstream infrastructure priorities. States such as Colorado and Canada’s Banff National Park have demonstrated that strategically placed overpasses and underpasses can slash animal‑vehicle collisions by up to 90%, while simultaneously reconnecting fragmented habitats. Wyoming’s new Kemmerer South project adds to this momentum, targeting a critical 30‑mile migration corridor for mule deer and pronghorn, and reflecting a broader shift toward ecosystem‑friendly road design.

The economic calculus behind the Wyoming initiative is compelling. With an estimated 6,000 big‑game collisions each year, the state incurs $20‑23 million in wildlife‑related costs and an additional $24‑29 million in personal‑injury expenses. By projecting an 80‑90% reduction in crashes, the $38 million investment could recoup its outlay within a few years through fewer vehicle repairs, lower insurance claims, and reduced emergency response expenditures. Moreover, improved safety translates to fewer driver fatalities and injuries, delivering measurable public‑health benefits that extend beyond the balance sheet.

Funding this project required a collaborative blend of federal, state, and private resources, exemplifying a scalable financing model for future crossings. The Federal Highway Administration’s $24.3 million grant, combined with WYDOT’s $4.2 million allocation and contributions from nonprofits, underscores the growing willingness of diverse stakeholders to share costs for environmental stewardship and road safety. As policymakers grapple with climate resilience and infrastructure renewal, Wyoming’s approach offers a template: leverage federal grants, engage local partners, and prioritize designs that protect both motorists and wildlife, thereby aligning transportation goals with broader sustainability objectives.
