Current project status

West Seattle Link Extension moving forward in updated Sound Transit 3 (ST3) System Plan  

On May 28, the Sound Transit Board adopted an updated ST3 System Plan to guide the next phase of transit expansion projects across the region. Under the updated plan, the West Seattle Link Extension project is moving forward with design and construction. We will continue engaging the community as we begin final design, acquire the land needed to build the project, and start early work.  

Project updates reduce costs and community impacts  

Over the past 18 months, work on the West Seattle Link Extension project has focused on identifying, evaluating, and implementing measures to reduce the project cost and community impacts, and maintain rider experience on the future Link line.  

The most notable change to the West Seattle Link Extension is the removal of Avalon Station. Eliminating Avalon Station shifts more of the route to a tunnel. In turn, this also reduces the project cost and community impacts, and the number of properties needed for construction. In total, we identified over $2 billion in cost savings, while keeping stations at SODO, Delridge, and Alaska Junction. In the coming months, we will work to confirm these design refinements with the Federal Transit Administration.

What’s next for the project?  

Sound Transit will continue engaging communities on station design and access projects, development near stations, public art, and construction planning.  

We will contact affected property owners, tenants, and businesses as more information becomes available. We are committed to working closely with affected residents and businesses throughout the process to provide individualized support, relocation assistance, and benefits.
