This bridge was constructed as the replacement for the Folsom Truss Bridge. Visit that bridge's page for a detailed history of the interesting story that these two bridges share.

This bridge is an outstanding example of a concrete arch bridge both for its span length and also for its unusually high level of aesthetic treatment. The arch ribs, arch columns, piers (especially those at the ends of the arch span) all have detailing designed to enhance the visual appearance of the bridge. In between the arch columns, concrete beams support the deck. The fascia beams between the columns were designed with an attractive arch shaped. This was not constructed as a utilitarian bridge, it was designed to be a signature bridge for Folsom. In 1969, the bridge was widened slightly. Additional deck beams appear to have been added to support the wider deck, but these beams were designed with the same arch shape as the original fascia beams, maintaining the original aesthetic appearance. On top however, the same sensitivity to historic integrity was not given. The original railings were replaced with ugly tube and parapet railings. Recommended future preservation work for this bridge would be to replace these railings with replicas of the original railing. The replicas could be carefully designed interior reinforcement so that they provide crash protection while still offering the appearance of the original railings. One can only assume the original railings were just as visually pleasing as the rest of the bridge. The missing original railings are really the only thing holding this bridge back from being one of the most beautiful concrete bridges in California.
