State Route 90 (Interstate 90), Asahel Curtis Interchange to Snoqualmie Summit, King County, Washington
The highway construction project is located in the upper reaches of the South Fork of the Snoqualmie River in King County and upgrades 5.14 miles of existing Interstate Highway 90 just west of Snoqualmie Pass to current Interstate standards. The proposed project begins approximately one mile west of the existing SR 90 bridge and proceeds in an easterly direction for approximately 0.8 mile along the existing highway. At this point, the Asahel Curtis Interchange will be located. As the project proceeds easterly from the Asahel Curtis Interchange, the roadways for eastbound and westbound travel separate to follow independent alignments along opposite sides of the valley. As these separated roadways approach the narrowing end of the valley near Snoqualmie Summit, they converge and join the existing SR 90 roadway immediately west of the recently completed West Summit Interchange. Completion of this project will provide both cross-Cascade Mountain traffic and Snoqualmie Summit recreational traffic with a fast, safe, and efficient transportation system for a projected period of twenty years. Other environmental impacts include potential water erosion, removal of timber, acquisition of natural wildlife habitat, and restrictions on wildlife travel patterns.
