    This is a recent post card acquisition of the Frisco’s bridge over Williams Creek at Mt Vernon, MO. The structure is an usual combination wood-steel, pin-connected pony truss. Whenever possible, the Greenfield and Northern railroad held-down construction costs by limiting earthwork, and by foregoing concrete/masonry work in its bridges. In this case, 4, 8-pile bents supported the 71 foot truss. During November 1922, the Frisco replaced the truss with 4, 5-pile bents.
