The total length of the Dumbarton Bridge is 1.6 miles, although the distance between its east and west intersections, where drivers can get off CA 84, is nearly six miles.
Tolls on the Dumbarton Bridge are collected in the westbound direction only, at a toll plaza located just east of the bridge spans, in Newark.
The Dumbarton Bridge also has a distinction not shared by other San Francisco Bay Area bridges: Just west of the span can be found the home offices of Facebook, famously located on Hacker Way.
