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.
George Washington Bridge Since 2006, the bridge has flown the world's largest free-flying American flag, measuring at 90 feet (27 m) long, 60 feet (18 m) wide, and 450 pounds (200 kg). It is hoisted on special occasions when weather allows,[27][28] and appears on Martin Luther King, Jr. Day, Presidents Day, Memorial Day, Flag Day, Independence Day, Labor Day, Columbus Day, and Veterans Day, as well as on dates honoring those lost in the September 11 attacks. On events where the flag is flown, the tower lights are lit from dusk until 11:59 p.m in the evening.[1]
