who designed the sundial bridge in redding ca
Sundial Bridge at Turtle Bay The Sundial Bridge is a cantilever spar cable-stayed bridge, similar to Calatrava's earlier design of the Puente del Alamillo in Seville, Spain (1992). This type of bridge does not balance the forces by using a symmetrical arrangement of cable forces on each side of its support tower; instead, it uses a cantilever tower, set at a 42-degree angle[9] and loaded by cable stays on only one side. This design requires that the spar resist bending and torsional forces and that its foundation resists overturning. While this leads to a less structurally efficient structure, the architectural statement is dramatic. The bridge is 700 feet (210Â m) in length and crosses the river without touching the water, a design criterion that helps protect the salmon spawning grounds beneath the bridge.[10] The cable stays are not centered on the walkway but instead divide the bridge into a major and minor path.
Golden Gate Bridge Irving Morrow, a relatively unknown residential architect, designed the overall shape of the bridge towers, the lighting scheme, and Art Deco elements, such as the tower decorations, streetlights, railing, and walkways. The famous International Orange color was originally used as a sealant for the bridge.[23] The US Navy had wanted it to be painted with black and yellow stripes to ensure visibility by passing ships.[13]
