The Foresthill Bridge over the North Fork of the American River is the highest (deck height) bridge in the U.S. state of California and the fourth highest in the United States. It is sometimes referred to as the Auburn-Foresthill Bridge or the Auburn Bridge.
Originally constructed to accompany the unbuilt Auburn Dam, the bridge stands 731 feet above the riverbed. It was fabricated in 1971 by Kawasaki Heavy Industries in Japan, built by Willamette Western Contractors, and opened in 1973. The bridge spans the North Fork of the American River in Placer County between the city of Auburn and the town of Foresthill in the Sierra Nevada foothills. Pedestrians can walk the length of the bridge in both directions. There is anti-Auburn Dam graffiti, showing protest of the planned dam, on the bridge's underside. A seismic retrofit project was begun in January 2011 and will cost an estimated 74.4 million dollars.The original bridge cost less than 13 million dollars.
The bridge can be seen in the beginning of the action movie xXx  in which Vin Diesel's character Xander Cage is seen driving a stolen red Chevrolet Corvette off of it, then jumping from the car mid-flight and parachuting to his accomplices at the bottom of the American River Canyon. It also appears in a montage sequence toward the end of the romantic comedy The Ugly Truth.[Source]
