Lake to Sound Trail construction updates

Since ground was last broken on the SeaTac segment of the Lake to Sound Trail in April, construction has neared more than 40% of completion. As a multi-municipality and agency collaboration between King County Parks, WSDOT, the Port of Seattle, and the five cities of Des Moines, SeaTac, Burien, Tukwila, and Renton, the Lake to Sound project links up sections of a 16-mile recreational trail spanning from the south end of Lake Washington in Renton, all the way to the shoreline of Puget Sound in Des Moines.

As of early September, nearly half of the trail, extending between 200th to 192nd in SeaTac, has been fully paved. Once completed, the 2.2-mile trail will connect the south terminus of Segment B (the 1.5-mile trail along Des Moines Memorial Drive from S. 156th St to S. Normandy Rd.) to the Des Moines Creek Trail at S. 200th St., roughly following the SR509 extension alignment.

The project contractor, Active Construction, Inc. has installed:

  • 1,700 square feet of retaining wall
  • 2,354 square feet of soldier pile wall 
  • More than 2,300 linear feet of steel piles for the boardwalk
  • 1,900 tons of asphalt 
  • More than 600 linear feet of storm pipe
Steel pilings and reinforcements that will support the future boardwalk.

Planned completion for the SeaTac segment (1.8 miles) is in May 2023. The Burien segment (0.4 miles) should be completed by Winter 2023. The project is funded by WSDOT, RCO, and the 2014-2019 Parks, Recreation, Trails and Open Space Levy.

The trail remains closed to public use until fully completed in 2023.
