Mountains to Sound Greenway - I-90
Bicycle/Pedestrian Facilities
A connected network of trails for walkers, hikers, bicyclists, equestrians, and handicapped visitors is a fundamental part of the Greenway concept. Towns, counties, and agencies in the I-90 corridor have adopted plans to complete links for a trail system that will lead from Seattle through rural areas to the mountains and a connection with the cross-state John Wayne Trail. This system will be managed by the State Parks.
Existing trails are paved or gravel, and they are designed to meet state safety requirements. The I-90 right-of-way can be traveled by bicycle for the entire length of the Greenway, including separated and landscaped trails along urban portions of the highway. Many recreational trails exist along the corridor in lands managed by the U.S. Forest Service, the State Department of Natural Resources, State Parks, and private lands. Existing trails and missing links are all documented in the Washington Department of Transportation's Mountains to Sound Greenway Implementation Plan, Vol. 4.
There are many significant trails found near the I-90 corridor. When linked, they will provide a continuous Mountains to Sound Greenway trail system in the I-90 Greenway corridor. Existing trails include:
- Seattle I-90 corridor trail: 13.5 miles to Bellevue
- Eastgate I-90 trail: 1 mile
- Issaquah/High Point Trail: 1 mile
- High Point/Preston link: 3 miles
- Preston/Snoqualmie Trail: 6 miles
- Snoqualmie Centennial Trail: 2 miles, paved
- Snoqualmie/North Bend/Cedar Falls Trail: 6 miles, gravel
- Cross-state John Wayne Trail: 60 miles east from the Cedar Falls trails and accessible at seven points along I-90. This trail is handicap accessible at one point. With repairs now underway, this trail will provide a continuous, easy grade, handicap accessible, unpaved trail to the Greenway terminus at Thorp.
