Description 

Opened for service March 23, 1912 for the standard gauge 7-mile Mt. Quarries Railroad that ran from the limestone quarry in El Dorado County to the mainline in Auburn. This bridge was the largest reinforced concrete railroad bridge in California at the time it was constructed.

The bridge was pressed into service as a one lane bridge for a period in the mid-1960s, whilst the highway 49 bridge was being rebuilt after being washed out in a flood. The bridge didn't have a guardrail, which made crossing somewhat hairy. This is where the bridge's common name, "No-Hands Bridge" originates from.

The bridge's architect & engineer, John B. Leonard, was a pioneering bridge engineer & architect, as well an early advocate for reinforced concrete structures.
