A 16-Mile Trail When Complete
The new section runs south along Des Moines Memorial Drive from South Normandy Road to 200th Street in SeaTac. It connects the southernmost stretch of the Lake to Sound Trail that ends at Puget Sound to the completed section that runs along the western edge of Seattle-Tacoma International Airport with convenient access to Sound Transit’s Angle Lake Station.
When completed, the Lake to Sound Trail will be a 16-mile non-motorized, multi-use recreational trail spanning from the south end of Lake Washington in Renton, all the way to the shoreline of Puget Sound in Des Moines when complete.
The Lake to Sound Trail will offer seamless connections to other King County regional trails, including the Interurban Trail, Green River Trail, Cedar River Trail, and Eastrail, the emerging north-south spine of the Central Puget Sound regional trail network known as Leafline.
The trail expansion was made possible by funding from the voter-approved King County Parks Levy, the Washington State Department of Transportation, the Port of Seattle, and the Washington State Recreation and Conservation Office.
