Somewhere in the Sierra Nevada foothills, a four-lane bridge crosses a canyon so deep that the river below looks like a pencil line drawn on stone. The Foresthill Bridge hangs 730 feet above the North Fork of the American River, making it the tallest bridge in California and the fourth tallest in the United States. But the remarkable thing about this bridge is not its height. It is why it was built. In the late 1960s, the Bureau of Reclamation planned to dam the American River canyon and flood it into a massive reservoir. The bridge was supposed to cross above the surface of that lake, replacing a lower road that would vanish under hundreds of feet of water. The dam was never finished. The lake never formed. And the Foresthill Bridge has spent more than fifty years spanning a canyon of open air and whitewater instead of the placid reservoir it was designed to overlook.

The Auburn Dam was supposed to be enormous -- more than 600 feet of concrete rising from the canyon floor, backing up a reservoir that would stretch for miles into the foothills. Construction began in 1975, two years after the bridge opened. Then, on August 1 of that year, a magn...

Foresthill, a small town of roughly 1,500 people nestled in the pine-and-oak woodland above the canyon, depends on the bridge for its primary connection to Auburn and the wider world. Without it, the driv...

In the opening sequence of the 2002 action film XXX, Vin Diesel's character drives a stolen red Chevrolet Corvette off the bridge deck, leaping from the car in midair and parachuting to accomplices waiting at the bottom of the canyo...
