In 1910, the Mountain Quarries Company contracted for the construction of a railroad bridge over the North Fork of the American River to haul limestone from their upstream quarry. The bridge and 17 wooden trestles were part of Mountain Quarries Railroad (MQRR) which went seven miles up to Auburn.

The MQRR Bridge, designed by John B. Leonard, was completed and placed in service on March 23, 1912 at a cost of $300,000. The bridge was reported to be the "longest span concrete arched bridge for railroad traffic owned by 'private capital' in the world" at the time of its completion. The bridge is 15 feet wide at the top, 482 feet long and 75 feet high. Each of the three arches has a span of 140 feet.
