Sound Transit released a three‑minute 3D flyover simulation video of the light‑rail extension linking the SODO district and West Seattle on October 9, 2026.
The video, using design data up to July 2026, depicts the planned tunnel segment and highlights design decisions and real‑world soil conditions.
The simulation visualizes the tunnel that will connect downtown Seattle’s SODO area with West Seattle, including the Alaska Junction, as part of Sound Transit’s expansion effort.
