Amador County, California Bridges: Pitt Street Bridge across the Middle Fork of Jackson Creek


March 2013 (38.35000°, -120.77083°) Pitt Street Bridge
At the intersection of State Routes 49 and 88 is the county seat of Jackson. The most important historic bridge in town is the Pitt Street Bridge over the Middle Fork of Jackson Creek. This 46 ft long bridge is a half-hipped Pratt pony truss built in 1902. It has a timber deck with a single traffic lane and a sidewalk cantilevering from the side of the truss.
The bottom chord is a tiny tension member that appears to be bowed downward from the weight of the floor beams. The bridge has sufficiency rating of 22.8 out of 100 and carries 500 vehicles a day. It's a 111 year old bridge that's eligible for (but has never been added to) the National Register of Historic Places.
