GENERAL WILDLIFE ALONG THE I-90 CORRIDOR
The I-90 corridor for this project is defined as the 15-mile stretch along I-90 between Hyak (immediately east of
Snoqualmie Pass), at milepost 54, and Easton, at milepost 70 (Figure 5). The I-90 survey areas in 2018 monitored
priority areas within close proximity to a few of the the 11 completed wildlife crossing structures or areas which
have been planned as future wildlife connectivity improvements as part of the I-90 Snoqualmie Pass East Project.
Two of the survey areas, Gold Creek and Price Noble, are in wildlife travel corridors leading to completed wildlife
crossing structures. Easton is monitoring a location planned for a future crossing structure. These installations,
established in the I-90 corridor, detect general wildlife movement and presence adjacent to the wildlife crossing
structures. Our efforts totaled eight discreet locations being monitored and 1,531 trap nights accounting, for 14.1
percent of our monitoring efforts (Table 6, Figure 2).
