Mercer Island, WA
Light Rail Station
Estimated Completion 2023
Mercer Island Station evolved through unique design constraints. The train trackway leading up to the station is located on one of the longest floating bridges in the world, taking over what used to be the I-90 HOV lane and utilizing the existing infrastructure.
DESIGNING A COMPACT FOOTPRINT
Since the station had to fit between the east and westbound I-90 highway lanes, the design team decided to stack the station program in order to minimize its footprint. The building cantilevers over the train trackway with “saddle bags”, giving the station its unique shape.
The station connects the city center of Mercer Island to Seattle and Bellevue, providing residents with options for access to employment and entertainment. Pedestrians and bicycles have direct access to the station entrances from the adjacent I-90 trails.
This station is served by two entrances from the street level into the platform. The glass station entrance buildings act as beacons to the neighborhood. Large cantilevered roofs provide weather protection and act as a welcoming gesture to patrons.
