Title
80 foot pony truss - detail of the lower cord pin connection, typical of the 80 foot trusses and similar to the 64 foot truss, where the vertical lace post joins the upper and lower chords. There are two pair of each 80 foot truss and a single pair on the 64 foot truss for a total of 22. The view also shows the chord eye bar and eye rod along with the diagonal bar and rod members. The rod hanging diagonally to the left is a broken lateral member. A four inch conduit is also in view. - Weidemeyer Bridge, Spanning Thomes Creek at Rawson Road, Corning, Tehama County, CA
