Mountains to Sound Greenway Trail

The Mountains to Sound Greenway is a 100-mile landscape surounding I-90 that stretches from the Seattle waterfront to Central Washington. Featuring wildland hiking and biking trails and a regional trail network that is used by pedestrians and bicyclists for recreation and community purposes, the Greenway connects it all. The 3.6-mile trail being studied would close a gap in the Greenway between Factoria Boulevard and Lakemont Boulevard.

In 2013, the city will begin the final design on the Greenway Trail between Factoria Boulevard SE and 150th Avenue SE. The design will follow the layout and recommendations made in the Mountains to Sound Greenway Trail Design Study which was completed in 2012.
The alignment was chosen as part of a study of the entire Eastgate/I-90 corridor, the Eastgate/I-90 Land Use and Transportation Project. The grant for the trail study was awarded through the National Scenic Byways program.
Background
There are a number of barriers for cyclists and pedestrians in the Eastgate/I-90 corridor, notably the gap in the the MTS Greenway. Many ideas were considered as part of the Eastgate/I-90 Land Use and Transportation Project on how to address the “Eastgate Gap.” Community input represented an important consideration in the assessment of trail alignment options.
On July 26, 2011, Bellevue staff held an outreach ride for residents to experience first-hand what it is like to ride a bike along the missing link in the Greenway. An online questionnaire was sent to cyclists who joined the ride to obtain input and reactions on their experience with the present state of the corridor and future development of the trail.
Input from this process is summarized in the Outreach Bike Ride Summary Report. Responses during the ride and in the online questionnaire indicated that riders prefer the southern alignment because it is the most direct and continuous route. Input from this process prompted the project’s citizen advisory committee to endorse the pathway depicted in the proposed Mountains to Sound Greenway alignment.
The alignment on the south side of I-90 chosen as part of a study of the entire Eastgate/I-90 corridor, the Eastgate/I-90 Land Use and Transportation Project. The grant for the trail study was awarded through the National Scenic Byways program.
With a $158,312 grant from the Federal Highway Administration, the city, in partnership with the Mountains to Sound Greenway Trust, completed a design study of trail alignment along the south side of Interstate 90 in 2012.
