Construction Plan (January 2011)

Trail Description

The East Lake Sammamish Trail (ELST) is an alternative non-motorized transportation corridor and multi-use recreational trail along 11 miles of former Burlington Northern Santa Fe railroad corridor on the east side of Lake Sammamish, from Redmond to Issaquah. King County purchased the corridor in 1998 and opened an interim gravel trail in 2006. King County Parks has spent more than 10 years on master planning, design work, and environmental review for this project, with ongoing involvement of a citizen’s advisory group, and close coordination with the cities of Redmond, Sammamish, and Issaquah.

Part of the “Locks to Lakes Corridor,” the ELST is currently the 11-mile “missing link” in the 44-mile long regional trail corridor that will connect the Burke-Gilman Trail, the Sammamish River Trail, the Marymoor Connector Trail, and the Issaquah-Preston Trail, linking Seattle to the Eastside and the Cascade Foothills. The trail will provide greater access to recreation, employment, and retail in the cities of Redmond, Sammamish, and Issaquah and provides a multi-use path for bicyclists, pedestrians, joggers, walkers, and movers of all ages and abilities. The ELST will be designed and constructed in segments. Read more about its design and construction in the "Project Information Segment" above.

Why is King County developing the East Lake Sammamish Trail?

The East Lake Sammamish Trail is currently an 11-mile “missing link” in a 44-mile-long regional trail corridor that will connect the Burke-Gilman trail, the Sammamish River Trail, the Marymoor Connector Trail, and the Issaquah-Preston Trail, linking Seattle to the Eastside and the Cascade Foothills. This type of paved trail has the highest degree of accessibility to people of all ages and abilities. The trail will provide greater access to recreation, employment, and retail opportunities in the cities of Redmond, Sammamish, and Issaquah, and provide a multi-use path for bicyclists, pedestrians, joggers, and other outdoor enthusiasts.


A trail for the community – Trail safety and accessibility are Parks primary goals. The new trail features a 12-foot wide asphalt surface with two-foot gravel shoulders and a one-foot clear zone on each side of the trail. The ELST project provides improved intersections, clear sight lines, consistent signage and improved drainage. Environmental improvements include enhancing wetlands, stabilizing slopes, installing fish passable culverts, and planting native landscaping. The redeveloped trail will benefit people of all ages and abilities – providing safe and healthy activities for families, individuals, and communities to enjoy.


Trail History

A trail 45 years in the making – For over 100 years, the East Lake Sammamish corridor existed as a railroad, used to move goods through the area. The King County Urban Trails Plan first identified the stretch of railbed between Redmond and Issaquah as a critical future link in the Regional Trails System in 1971.

Burlington Northern Santa Fe Railway ceased operations on the track in 1996. Cascade Land Conservancy acquired the corridor in April 1997 and King County purchased the property in September 1998. The following year, King County began a robust, region-wide community engagement effort to guide development of the Trail Master Plan.
