Showing partial side view of swing span in closed position. The two (2) arms act as simple spans, a small amount of negative bending is accommodated by the continous top and bottom truss chords due to a continuous condition. Note the inclined end post of each of the simple spans, the operator's house, center/pivot pier and the pivotal pole-line pole placed atop of bridge. - Bridgeport Swing Span Bridge, Spanning Tennessee River, Bridgeport, Jackson County, AL Stock Photo
