This conceptual design features a pedestrian bridge connecting historic Pike Place Market to the revitalized waterfront and a four-ft-deep, 100-ft-long landscaped “lid” over Elliott Avenue, supporting a structurally integrated two-story building and offering public open space. The lid design includes a landscaped finish providing 20-ft minimum clearance over the roadway. The low-rise building, "Building B," utilizes a portion of the lid, cantilevering over the top with a 2-story-deep steel truss, with wide flange steel beams supporting concrete on steel decking for the upper level and roof. The foundation design also navigated several challenges—the 4-ft-in diameter drilled concrete shafts were required to be located away from the existing Viaduct foundations, and the existing T4 electrical transmission line, all of which had to be coordinated with the Elliot roadway construction. MKA’s civil engineers reviewed the lid’s conceptual design options to provide alternative framing ideas and potentially reduce costs, as well as coordinated with a separate team designing a nearby aquarium to reach solutions for storm drain collection.
