Washington's Animal Highway Lanes

"On a 15-mile stretch of Interstate 90, between here and Hyak, road crews clear an average of 50 deer and elk carcasses a year. They don't keep track of the smaller roadkills, such as raccoons and foxes, because there are too many... The proposal calls for building a system of wildlife pathways that would allow animals to safely cross that section of I-90. The plan could cost as much as $100 million, making it one of the largest roadkill-prevention projects in the United States.

The Snoqualmie Pass project would include up to 14 crossings. Some would resemble large tunnels or culverts, and some would be bridges, including one that would span 1,200 feet — the length of four football fields — and be planted with dense, natural vegetation."
