About this landmark

Plaque text:

Mountain Quarries
Railroad Bridge
This bridge, built to carry limestone from nearby quarries to the city of Auburn, was a very early use of reinforced concrete in railroad bridge construction and the largest such railroad bridge in California at the time it was built in 1912. The bridge was designed by John B. Leonard, who became one of California's most renowned pioneers in the design, engineering, and promotion of the use of reinforced concrete.

Note

The bridge crosses the El Dorado-Placer county line. The plaque is on the El Dorado side.
