The Sundial Bridge is a signature feature of the Turtle Bay Exploration Park near Redding, California. It links the north and south campuses of the park through a single span 700 foot long bridge that crosses the Sacramento River. The bridge is interesting in a number of ways. First, there is only one set of cables, which means that the bridge does not balance with equal weight on each side of the tower. Rather, the tower is massive and supports the bridge through its sheer wight. Second, the tower is not exactly vertical. Rather, it leans over opposite to the bridge. The tower forms a very large sundial, with its shadow pointing out the time of day, hence the name Sundial Bridge. Finally, the tower is not in line with the bridge span. Rather, it is position so the side of the bridge span, and the cables attach to one side of the bridge structure.
