Union Street Pedestrian Bridge
connecting Seattle’s pedestrians to the waterfront

The Union Street pedestrian connection is part of the Waterfront Seattle Master Plan and improves accessibility between Downtown Seattle and the Waterfront Promenade. The Lower Union connection is one of two parts envisioned (Upper Union as a future project) and provides a pedestrian bridge, stair, and elevator to create a direct and legible circulation path. Materials and finishes are all simple, integral, and expressive for a civic level of durability while providing a restrained backdrop for the art screen and a sculptural gateway over the stair. The CNC-milled bridge formwork uses the plasticity of exposed concrete to give scale and interest to a massive, high-load capacity structure. Stainless steel plate stanchions and cable mesh guardrail are visually light and essential, with a single stanchion profile used to serve multiple functions. Translucent laminated channel glass encloses the elevator tower, inviting the patron into the cab through transparent glass doors, then provides a brief experience of immersive, brightly illuminated travel between landings.
