A wildlife crossing is an engineered structure that allows safe and sustainable movement of wildlife across roads, highways, rivers and other barriers. They are designed to reduce interactions between wildlife and humans, roadkill, vehicle damage, and human injury, and enable safe passage for animals to access food, breeding grounds and other resources. This "wildlife bridge" will be a fully-vegetated, 150-foot wide overpass, similar to the successful ones built by Conservation Northwest on I-90.

Engineers have created and tested designs for similar bridges. CalTrans will be building the crossing once the location is finalized.

Fun fact: the wildlife crossing here in Siskiyou County may end up being the first overpass in North America made of fiber-reinforced polymer, a light, durable material that can include recycled plastic. This will reduce costs and improve the sustainability of the construction!

Shasta-Trinity Wildlife Group would be happy to connect you with our nonprofit partners. Please see our Get Involved page for details.

This is yet to be determined. Studies are still needed to identify the areas with the highest wildlife traffic, so that the bridge will have the biggest impact. Funding for these studies is one of the things the Shasta-Trinity Wildlife Group is working on.

Yes, we are designated a 501c(3) organization!

Like any other major roadway structure, the wildlife bridge is likely to take a couple of years to complete.

Wildlife are on the move here, between the Klamath-Siskiyou mountains, the Cascades, the Eddies, and the Trinities. They make daily movements to find food and mates, seasonal migrations as conditions change, and generational shifts claiming new territory to call home. We can't stop them from crossing the roadway, so instead we can give them dedicated, traffic-free crossing points. This will keep wildlife off the freeway, thus preventing animal/vehicle collisions.
