Notes
The bridge connects downtown Seattle with the Colman Dock Ferry Terminal over a new promenade and reconfigured Alaskan Way. It replaced a narrow, unattractive pedestrian bridge. The new bridge acts as a gateway to the city along the improved waterfront with excellent views of Elliott Bay and beyond. The Marion Street Bridge includes a main span over the Alaskan Way and two balancing, long cantilevers that allowed the bridge to be built independently of the new ferry terminal and future buildings along the waterfront. The main reinforced concrete piers are sculptural, well proportioned, and illuminated at night.
