Sound Transit Capitol Hill Station
General contractor: Turner Construction Co.
Owner/developer: Sound Transit
Primary designer: Hewitt
Sound Transit’s Capitol Hill Station covers three discontinuous city blocks and required three disparate above-ground station entrances.
The north entrance is located at the intersection of John Street and Broadway, the west entrance is located on the west side of Broadway and is accessed by a cut-and-cover underground pedestrian concourse, and the south entrance is located at Denny Way and Nagle Place.
The light-rail station serves a densely populated neighborhood and business district, and connects people to downtown Seattle and the University of Washington.
Turner provided pre-construction and construction services for this complex project where 90 percent of the work was done underground. The scope of work included open-cut-retained excavation; below- and above-grade structures; vertical and horizontal waterproofing; station finishes, including conveyance systems and mechanical and electrical systems; and restoration of at-grade features, including streets, sidewalks and landscaping.
