Description 

from the county survey: "The single-span pin-connected Pratt thru-truss bridge is supported on random ashlar abutments with U-type wingwalls. The trusses appear to be original with the exception of the floor beams, stringers and deck that have been recently replaced, the addition of welded corner braces to the top laterals, and welded braces extending from the portal struts to the exterior floor beams. The trusses are pin-connected throughout. The portals and top chord consist of two channels, a cover plate and lacing. The intermediate verticals consist of two channels with lacing. The lacing on the verticals parallels the bridge centerline. The bottom chord eyebars and diagonal eyebars have forged eyes. The counters are provided with sleeve nuts for adjustment. The end panel vertical hanger has a fourprong, claw-like ends which engage the pins directly over and in line of the U-bolt floor beam hanger. Such an arrangement, also seen on King Bridge Company spans from the same era, means that the hangers are out of phase or reversed. The expansion bearings consist of nested rollers."
