Bridge History and Significance
Previous Structure In June 1892, the Shelby county board of commissioners contracted with the Indiana Bridge Company of Muncie, Indiana, to erect a 16-foot high Pratt through-truss structure extending 87-feet in seven panels with a 14-foot roadway for $1,225 over Conns Creek, about 1.5 miles southwest of Waldron. Haymond and Howard received a $1,016 contract to reinforce the floor of this bridge in October 1912. This structure may have been washed out in the great spring flood of 1913. Surveyed Structure Concrete abutments and wingwalls support the single-span Warren pony truss. The riveted structure extends 87'6" in seven panels. Its all-interior verticals are manufactured from pairs of angles riveted together with stay plates and reinforced with external sway bracing. Its diagonals are made from a pair of angles (doubled in the outer panel) also riveted together with stay plates. The I floor-beams are riveted to gussets and the verticals above the lower chord and carry the concrete deck. The weight and varied size of the diagonals, the placement of the floor-beams, and the integration of knee or external sway braces into the verticals indicate a late stage in the design of all-riveted Warren pony trusses. This altogether undecorated bridge retains its original members. References Previous Structure Indiana Bridge Company, "Contract Index," #734. Shelby County, "Commissioners Record," L: 387; S: 189.
