The Sundial Bridge is a cantilever spar cable-stayed bridge for use by bicycles and pedestrians. She spans across the Sacramento River at 700 feet, while the support tower itself forms a single 217-foot (66 m) mast that points due north at a cantilevered angle, allowing it to serve as the gnomon of a sundial. The shadow cast by the tower is exactly accurate on only one day in a year on summer solstice. 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.
We also took a walk along the McConnell Arboretum & Garden trails and though the plants were drab in their winter state, we saw plenty of wildlife including red tailed hawks, turkey vultures, osprey, storks, hummingbirds and common mergansers.
