This extremely rare and highly significant Phoenix column truss bridge has an interesting history. It was originally located over Gienega Creek south of San Jose, California, on the Southern Pacific Company Coast Line. In 1919, it was relocated here to Mill City. At the time it was relocated it appears some alterations were made. Because the alterations themselves are so old as to be themselves historic, this is an interesting bridge to "read" because one must look closely to see how the bridge was altered. Notably, the hip verticals (likely eyebars originally) were replaced with built-up beams. The sway bracing and portal bracing were altered. The original ornamental cast iron portal bracing knees that one might expect to find on a Phoenix truss bridge were replaced with a simpler design. Empty holes on the end posts and vertical members indicate that the bracing knees were replaced with something different. The horizontal struts of the sway bracing also appear to be spliced, suggesting perhaps the width of the bridge was changed when it was moved.
In the bridge's more recent history, the railroad line it served was abandoned and converted into a rail-trail. As of 2018, Mill City was raising funds to restore the bridge. As one of Oregon's oldest and rarest historic bridges, this is certainly a worthwhile endeavor.
This bridge is next to a historic highway bridge.
