Sacramento County, California Bridges: Cosumnes River Footbridge

April 2013 (38.49219 degrees, -121.09140 Degrees) The Yellow Bridge
Next to yesterday's State Route 16 Bridge is a pretty, yellow pedestrian truss bridge. The Cosumnes River Footbridge was built in 1908 and may have carried the Jackson Highway before the box girder bridge was built in 1952. This yellow bridge is a 227 ft long Pennsylvania Petit through truss with a Pratt truss approach span. According to Wikipedia, this type of truss bridge has "half-length struts or ties in the top, bottom, or both parts of the panels."
I did see some long ties at the bottom of the sway braces but I didn't see any half length struts or ties. Maybe they're talking about the long diagonal members that cross two panels. What I did notice about this and other Pennsylvania Petit trusses is that they are very long bridges with slightly rounded tops.
I wasn't able to walk on the deck of this bridge, because it was only for golfers who live in Rancho Murieta, which is a huge gated community.
