West Seattle and Ballard Link Extensions

Project Highlights

Mode:

  • Link light rail

Start of service:

West Seattle Link Extension: 2030
Ballard Link Extension and new downtown Seattle Light Rail Tunnel: 2035

Overview:

The West Seattle and Ballard Link Extensions will provide fast, reliable light rail connections to dense residential and job centers throughout the region while the new downtown Seattle Light Rail Tunnel provides capacity for the entire regional system to operate efficiently.

Per the voter-approved ST3 plan, the representative project for the West Seattle Link Extension builds light rail from West Seattle's Alaska Junction neighborhood to downtown Seattle primarily on an elevated guideway with a new rail-only fixed span crossing of the Duwamish River. The West Seattle Link Extension will connect to existing Link service, continuing north to Lynnwood and Everett.

Per the voter-approved ST3 plan, the representative projects for the Ballard Link Extension and downtown Seattle Light Rail Tunnel build light rail from Ballard's Market Street area through downtown Seattle with both tunneled and elevated alignments and a rail-only movable bridge over Salmon Bay. These connect to Link service, continuing south to Tacoma.
