MODIFIED PARKER THROUGH TRUSS
1926 Muskogee 51E0835N4350004 J.A. Moore
Bridge builders also modified the Parker by subdividing the panels to supply more stiffness for the major structural elements and more support for the floor system. The four 180-foot, riveted spans of the modified Parker over the Grand River illustrates this type. A local contractor erected the bridge at Fort Gibson in 1926. The type seemed well suited for the needs of a major bridge across a wide river (Figure 64).
Figure 64. Four modified Parker through truses form the main spans of Bridge 51E0835N4350004. The 1926 structure crosses the Grand River at Fort Gibson.
