On Labor Day 1973, the Foresthill Bridge opened to the public. At an astounding height of 730 feet, it was the second-highest bridge in the world at the time and the highest in the state of California. The bridge outside of Auburn still holds the record as the state’s highest bridge by deck height and is the third-highest bridge in the country, according to National Geographic. … However, the bridge was made in preparation for an even bigger project that never came to be: the Auburn Dam and subsequent Auburn Lake.
