Ultimate Road Trip Guide: Davis to Tiburon, CA

The route from Davis to Tiburon spans approximately 85 miles via I-80 W and US-101 S, a journey that typically takes 1.5 to 2 hours without traffic. Yet this corridor encapsulates a dramatic transition: from the flat, agricultural expanse of the Central Valley to the rolling hills and coastal bluffs of the San Francisco Bay Area. A little-known fact: the section of I-80 through the Carquinez Strait is one of the few places where the highway crosses a major earthquake fault line—the nearby Hayward Fault runs parallel to the route. This geological undercurrent subtly shapes the landscape, from the trestle bridges to the shifting soils that challenge roadway maintenance.
