The Foresthill Bridge, which soars 730 feet above the stream bed of the American River's North Fork, is reputed to be the 3rd highest bridge in the United States and the tallest in California. The bridge opened for public use on Labor Day, 1973. The 2,428 foot long span, with piers only 16 feet shorter than those of the San Francisco Golden Gate Bridge, was built at a cost of $13 million by the Bureau of Reclamation.
The bridge was built to span Auburn Lake, the reservoir that would have backed up into the North and Middle Fork canyons of the American River behind the Auburn Dam, if it had ever been built. The dam project was abandoned and the bridge now spans the North Fork canyon.
