The idea is to reduce the number of animal and car collisions, and encourage animal populations arbitrarily sequestered by the interstate to intermingle again. Researchers pinpointed this crossing on I-90 as an important one for animals, especially herds of elk, who move out of the mountains to lower elevation when winter hits.
One study even found that male bears tended to use underpasses, while females and cubs stayed on top. Having both kinds of animal infrastructure is important, since some species are more likely to go over bridges, while some prefer tunnels, explains Hester for Atlas Obscura. One more overpass is planned on the I-90 Snoqualmie Pass East, along with additional bridges and large culverts under the highway. The $6.2 million project is the first in an ambitious plan to make Washington’s interstate more critter friendly, reports Eli Francovich at The Spokesman-Review. Still to come is fencing near the corridor that will help guide animals onto the overpass, and buffer car noise coming from below. Nice! Our camera captured the 1st image of #wildlife using the new I-90 overcrossing east of This coyote safely crossed the highway, avoiding traffic, anvils, ACME rockets & roadrunners! Excited to see what other species cross! /aQqnG0m9Wa- Washington State DOT December 6, 2018 Jessica Leigh Hester at Atlas Obscurareports that a video tweeted out this month by Washington State’s Department of Transportation (WSDOT) confirmed the overpass’ first user, a coyote who pranced across the elevated, vegetation-covered bridge. The path is for animals only and is intended to give elk, bear, and other creatures safe passage above the busy highway, which cuts through the North and South Cascades habitats.Īlready, the critter bridge, which is slated to be finished in 2019, is doing its job. A new overpass on Washington State’s Interstate 90 east of Snoqualmie Pass aims to change that. Country musicians may sing about the highway as a symbol of freedom, but for animals it’s a borderline where few cross and many never to return.
