Utah US 91 Wellsville Mountains Wildlife Crossing Structures

Mule deer and moose were documented since 2008 to heavily use a corrugated steel culvert at mile post (MP) 14 along US 91 in the Wellsville Mountains of northern Utah. The goal of this project was to learn of other species of animals that were within a half mile of the road but were not approaching the crossing struture. The hypothesis was that the species list for both at the structure and away from the structure at various distances would be identicial.

I-90 Snoqualmie Pass East

The I-90 Snoqualmie Pass East Project will reduce congestion, and improve safety and reliability along a 15-mile stretch of the highway from Hyak to the Easton, WA. The project corridor passes through the Okanogan-Wenatchee National Forest and intersects a critical north-south linkage zone for wildlife in the Cascade Mountains. Washington State Department of Transportation (WSDOT) and its partners will help alleviate the effects of the highway by constructing crossing structures that connect wildlife and hydrology across the landscape, and restoring habitat throughout the project area.

Interstate 280 Wildlife Connectivity Research Project

Interstate 280 is a busy highway on the San Francisco Peninsula. It is also adjacent to wild open spaces for about 20 miles. This means that the native wildlife that live in these wild areas sometimes attempt to cross the highway. When they cross the surface, they usually get hit by a car. This project provides access to wildlife cameras placed at under-crossings that might provide wildlife with a safe way to cross the highway, underneath.

I-680 Wildlife Crossing

This project is a case study for a Federal Highways Administration supported project developing remotely communicating wildlife cameras and server-side informatics tools. Wildlife populations in the East Bay open spaces are isolated from the rest of nature by I-680. There are very few crossing structures under this interstate, none of which were built for wildlife. Nonetheless, wildlife use these structures to move between the East Bay open spaces and the rest of the world. Without this movement, these populations would be isolated and subject to extinction.
