I-90, Cabin Creek I/C to W. Easton I/C Phase 3 - Add Lanes/Build Wildlife Bridges

Contract summary

I-90 Phase 3 is the second to last phase of the 15 mile Snoqualmie Pass East Corridor. This project, which is located east of Snoqualmie Pass within United States Forest Service (USFS) land on I-90, experiences significant congestion due to high traffic volumes, weather conditions, and vehicle collisions including vehicle collisions with wildlife.

The original concrete pavement is cracking and deteriorating and has been overlaid with Hot Mix Asphalt (HMA) to provide stop gap solutions but is in need of replacement. This project will reconstruct the interstate in accordance with the current design criteria between MP 64.4 to MP 70.1 as described in the 2008 Final EIS including: adding a new lane in each direction, stabilizing rock slopes, replacing truck climbing lanes, replacing stream crossings, constructing Hydrological Connectivity Zones (HCZs), constructing wildlife crossings, constructing retaining walls, constructing wildlife fencing, and adding ITS components.
