The Hospital Bridge (13C0005) is a rare surviving example of a steel pin-connected truss bridge that was once common throughout California. All structural members are original, and the bridge retains its original wooden deck. It carries only pedestrian traffic but was once the only access to the historic settlements and mining country upstream from the gold rush community of Downieville. In the wake of the 1937 flood it was the only intact bridge in the community until repairs were made. Additionally, this bridge is a rare example of California bridges constructed by the Western Bridge and Construction Company of Omaha, Nebraska.
