Sundial Bridge

Redding, California

This ultra-modern California span is actually a titanic solar clock in disguise. 


Checking your phone while riding your bike or even while walking can be hazardous but trying to read the time off Redding, California’s dual-purpose Sundial Bridge is probably even more dangerous since you’ll have to train your eyes much farther from the road. 

Opened in 2004, Sundial Bridge is a bicycle and pedestrian bridge that was built as both a useful span and a tourist draw. The bridge connects two separate parts of the Turtle Bay Exploration Park which is home to a number of delicate wildlife, and the bridge itself was built with the area’s creatures in mind as well. In order to protect a salmon habitat on one side of the bridge, a tall support spire was designed to hold it up from the opposite end only. Thus the slanted claw, from which the suspension cables hang, tilts over the path as part of a futuristic bit of public architecture. However the bridge’s tower also does double-duty as the dial of a giant sundial.

As the sun traces its arc across the sky, the shadow that it casts lines up with large stone markers that have been placed in a garden to the north of the bridge. Despite being kept by the rotation of celestial bodies, the time told by the bridge is only truly accurate during the Summer solstice when the sun lines up directly. On May 20, 2012, the bridge was in the central path of the annular solar eclipse that day.

Even if you can’t set your watch by it, the Sundial Bridge is one of those spans that is both part of the journey and a destination in and of itself.
