The Turtle Bay Sundial Bridge crosses the Sacramento River in Redding, California. Currently under construction, the bridge is scheduled for completion in Summer of 2004. The bridge connects the north and south areas of the Turtle Bay Exploration Park and serves as a starting point for Redding's Sacramento River Trail system.
Using cantilevering methods now familiar to Calatrava fans, the bridge will cross the river withouth the need for support structures in the water. In this way, aquatic life will remain undisturbed. This concept is of such importance for this project that the bridge is being built parallel to the river, and only when it extends its full length will it be swung out to be connected to the supports on the other bank.
The mast angles to the north, and will act as a sundial that can be read at the north end of the bridge. The bridge's deck uses structural glass, a material used by Calatrava in several other bridges.
