The Tukwila/International Boulevard Station serves as a multimodal transportation center including light rail and bus transit services plus adjoining park-and-ride lots. The sloping site informed the design of an elevated station structure suspended over a pedestrian plaza. Two elevated side platforms for light rail and a mezzanine with ticket vending machines and rider information are sheltered under an angular roof room that resembles uplifted wings. At the platform level, large glass windows provide views of Tukwila, Mount Baker, and the SeaTac Airport control tower.
HEWITT provided architecture, urban design, and landscape architecture for the station. Coordination with with the cities of SeaTac and Tukwila, WSDOT, and Sound Transit regarding bus, auto, and pedestrian circulation systems was critical for commuter safety and convenience, as well as the integration of site program elements – station plaza, parking trays, public art, and pedestrian connections to City sidewalks.
As part of Sound Transit Art Program, the station houses four art installations: three works by sculptor Tad Savinar – A Drop of Sustenance; A Molecule of the Region; and Voices of Tukwila – and one by Clark Wiegman – Soundings.
