About the ELST

The East Lake Sammamish Master Plan Trail (ELST) includes design and construction of an alternative, non-motorized transportation corridor and a multi-use recreational trail along 11 miles of the former Burlington Northern Santa Fe (BNSF) railroad corridor on the east side of Lake Sammamish from Redmond to Issaquah. The trail will provide access to recreation, employment and retail in the cities of Redmond, Sammamish and Issaquah. 

The ELST is the missing link in a 44-mile urban regional trails system linking Puget Sound in Seattle to the hub of east King County and on to the Cascade Foothills. 

This project has developed in two stages:
The Interim Use Trail, which was completed in 2006, originally extended south from NE 70th Street in Redmond to Gilman Boulevard in Issaquah and features a crushed gravel surface. 

The ELST is being constructed in phases as funding allows. Construction includes a 12-foot-wide asphalt trail with two-foot soft surface shoulders and one-foot clear zones on each side of the trail. Other elements include: retaining walls, improved intersections/traffic controls, improved drainage systems, fish passable culverts, bollards, native landscaping, fencing and other trail amenities. The Master Plan Trail also includes plans to construct a total of three parking lots (2 with restrooms) at NE 70th St in Redmond (completed), Inglewood Hill in Sammamish and SE 33rd St in Sammamish.

Segment Details

187th to Inglewood Hill Rd - 2.6 miles

Redevelopment of the North Sammamish segment  begun April 2014. Due to the extensive amount of work, steep topography, and limited access, the entire trail segment will be closed for approximately one year. 

Trail safety and accessibility will be improved with a new 12-foot-wide paved corridor with two-foot soft surface shoulders on each side with enhanced intersections, open sightlines, and improved drainage.

Funding for this segment has been provided to date by the voter-approved 2008-2013 Open Space and Trails Levy and voter-approved the 2014-2019 Parks, Trails, and Open Space Replacement Levy. Other funding includes the federal Congestion Mitigation and Air Quality (CMAQ) program and the state Washington Wildlife and Recreation Program.
