''- Project Location: Completion Date: Project Cost: Olympia, Washington 2003 $30,000,000 Project Owner: City of Olympia, WA David Goodyear DGES Engineering Services I I I The 4th A venue Corridor Improvement Study involved the replacement of the Fourth A venue Bridge. The corridor links residential neighborhoods with the downtown commercial center and heavily used by pedestrians and bicyclists as well as motor vehicles. The bridge itself is in view from the state capitol building. The high visibility created tremendous interest from the public. H2L2 served as the architectural consultant to DGES and Associates/T. Y. Un International. Primary tasks included developing structural forms with the engineers and coordination with the Citizen's Advisory Panel (CVAC) and other public officials. H2L2 conducted extensive public education workshops and participated in public meeting presentations. H2L2's 3-D visualizations were essential in enabling the public to visualize and comment on alternative structure types as well as detail elements such as lighting and railings. Additional pedestrian enhancements for the multi-use corridor included bicycle lanes and "bulb outs" or pedestrian overlooks. Coordination with the Public Artist, selected by the City, was also required. The primary architectural ambition envisioned a bridge structure that would appear to "skip across the water". Other considerations included compatibility with the scenic Olympian Mountains, Puget Sound and other environmental features. The bridge aspires to work with varying natural light values, which differ dramatically from summer and winter. The design team with input from the CVAC evaluated five structure alternatives. These five were then narrowed down to three alternatives: a cable-stayed, a delta frame and a haunch girder. H2L2 ARCHITECTURE - INTERIOR DESIGN - PLANNING - INFRASTRUCTURE
