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.
Redding, California Redding, officially the City of Redding, is the county seat of Shasta County, California, in the northern part of the state. It lies along the Sacramento River, 162 miles (261 kilometers) north of Sacramento, and 120 miles (190 km) south of California's northern border, shared with the state of Oregon. Interstate 5 bisects the entire city, from the south to north before it approaches Shasta Lake, which is located 15 miles (24 km) to the north. The 2010 population was 89,861.[5][6] Redding is the largest city in the Shasta Cascade region, and it is the sixth-largest city in the Sacramento Valley, behind Sacramento, Elk Grove, Roseville, Vacaville and Chico.
