What is the common name of Calatrava's bridge in Redding, California?

The common name of Calatrava’s bridge in Redding, California, is the Sundial Bridge.

Also known as the Sundial Bridge at Turtle Bay, it crosses the Sacramento River and connects areas of Turtle Bay Exploration Park. Santiago Calatrava designed it as a pedestrian and bicycle bridge, and it opened on July 4, 2004. Its 217-foot mast points north and acts as the gnomon—the part of a sundial that casts the shadow.

The bridge’s design is often confused with a conventional road bridge, but it carries no motor traffic. It is a cantilever spar cable-stayed bridge, with the walkway suspended from cables on one side of the angled mast. The bridge is about 700 feet long and crosses the river without touching the water, helping protect salmon-spawning habitat. “Turtle Bay Bridge” is a tempting mix-up because of the park’s name, but Sundial Bridge is the established name.
