Construction will begin on the 2.2-mile segment of the Lake to Sound Trail on May 4 with the permanent closure of a segment of 18th Avenue South and South 196th Street in SeaTac to vehicular traffic.
These road segments are currently used as a local bypass of the South 200th Street and Des Moines Memorial Drive intersection and do not provide access to any residential properties. The streets are adjacent to WSDOT right-of-way and Port of Seattle property.
This is the third segment in the Lake to Sound Trail, which once complete, 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.
It is anticipated that this segment of trail will be open for use in late 2023.
When the trail is complete, the SeaTac and Burien will own and operate their respective segments. The SeaTac portion of the trail is funded by the WSDOT SR509 Completion Project and King County levy funds. The project meets a mitigation requirement for the WSDOT SR509 project.
The trail’s alignment has been closely coordinated with the alignment of the WSDOT SR 509 Completion Project. The new SR 509 project will physically cut off South 196th Street from Des Moines Memorial Drive and 18th Avenue South from South 200th Street, leaving the old segment of road disconnected from the rest of the street grid.
The City, County and WSDOT saw this as an opportunity to repurpose the disconnected road for a portion of the trail alignment. We have been involved in the project through design. King County will provide leadership on the design and construction management of the trail.
