Overlook Walk

This conceptual design features a pedestrian bridge connecting historic Pike Place Market to the revitalized waterfront and a landscaped “lid”—four feet deep and 100 feet long—over Elliott Avenue.  The lid supports a structurally integrated two-story building and offers 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 two-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 drilled concrete shafts, four ft in diameter, needed to be located away from the existing Viaduct foundations and T4 electrical transmission line, requiring coordination with Elliot Avenue 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 stormdrain collection.
