The Sundial Bridge

The Sundial Bridge is a cantilever spar cable-stayed bridge that spans the Sacramento River in Redding, California. It was designed by Santiago Calatrava and completed in 2004 at a cost of US$23,000,000.
This pedestrian bridge features a single 217 foot mast that serves as the gnomon of the world's largest sundial. Sundial Bridge shadow is cast upon a large dial to the north of the bridge, though the shadow cast by the bridge is exactly accurate on only one day in a year - the summer solstice, June 21. The tip of the shadow moves at approximately one foot per minute so that the Earth's rotation about its axis can be seen with the naked eye.
The bridge deck is surfaced with translucent structural glass, which is illuminated from beneath and glows aquamarine at night. The Sundial bridge is 700 feet in length and crosses the river without touching the water. The cable stays are not centered on the walkway but instead divide the bridge into a major and minor path.
