I5 Wildlife Crossing Project Aims to Protect Biodiversity and Motorists

The Oregon Department of Transportation (ODOT) is collaborating with the Southern Oregon Wildlife Crossing Coalition (SOWSCC) and various partners on an ambitious project that seeks to enhance the safety of motorists and protect the region’s diverse wildlife. The initiative involves creating wildlife crossings across or under Interstate 5 (I-5) in the Siskiyou Mountains region, spanning from Ashland to the California border.

Several locations along I-5 have been studied for potential bridge crossings. These include Milepost (MP) 1.6, which connects to the Mariposa Preserve, MP 2.7 at Bear Gulch, and MP 8.7 near Barron Creek. Additionally, undercrossings at MP 6/Old Siskiyou Hwy and Neil Creek/MP 10.3 are being considered. Among these candidates, priority is leaning towards the MP 1.6 Mariposa Preserve location, based on factors such as funding availability and constructability.

The SOWSCC emphasizes the importance of preserving biodiversity and promoting healthy wildlife populations through the conservation of passages between habitat types. These less developed lands provide essential habitat and valuable connectivity throughout the region.

As for the project’s financial aspects, the total cost and funding details are yet to be announced. However, there is a $3.5 million allocation for planning and design, with an estimated bridge cost of approximately $20 million. ODOT and the Siskiyou Wildlife Crossing Coalition are actively seeking avenues for construction funds, while the contractor for the project remains undisclosed.

The primary objective of this undertaking is to reduce animal strikes and fatalities on the highway, which affect various species such as black bears, deer, elk, and others. These incidents not only harm wildlife but also pose hazards to drivers and passengers, resulting in substantial medical claims and property damage. The estimated average collision cost is $9,000 for deer and $24,000 for an elk.

By mitigating wildlife strikes, this project aims to create safe corridors for animals to cross I-5, either beneath or above the highway. Ultimately, it seeks to bridge fragmented traditional wildlife corridors, offering a promising vision for the future of I-5 near the California-Oregon border – one that is greener and safer.

Currently, ODOT is awaiting word on whether the project will receive funding approval from the federal government. If approved, construction could commence as early as 2025, marking a significant step towards safer highways and protected wildlife in the Siskiyou Mountains region.
