This bridge is an extremely rare example of a bizarre bridge design that was the distinctive design of the Canton Bridge Company. These bridges, all built by the Canton Bridge Company are sometimes called lattice girders or are also sometimes called inverted kingpost truss bridges.
In reality, they are a blend of a girder and a truss bridge. The diagonal members that form the inverted kingpost truss design function as a pony truss. However the lattice that fills the entire web functions like a through girder, while also acting and looking like a traditional lattice railing for the bridge. However, classifying these bridges as inverted kingpost truss bridges makes sense, because this distinguishes them from other lattice girder bridges which lack the distinctive inverted kingpost diagonals.
With the other few examples of this bridge design in Ohio either demolished or altered, this bridge is distinguished as the best remaining example in the state. The bridge retains its decorative flower buttons on the lattice. It would appear that this bridge was many years ago relocated from somewhere else, but it is not known at this time where the previous location might have been. The bridge carries a private drive over a stream west of SR in Dillonvale. The driveway serves several residences ca.
The 1 span, pony truss bridge functions as an inverted king-post truss. The upper chord is built up from a plate that is curved at its ends. Riveted to the bottom side of the plate are longitudinal angle stiffeners that also form connection points for the lattice bar railings.
At the curved haunches of the upper chords are gusset plates to which are attached a pair of diagonal angles. At mid-span, the diagonals support a rolled floorbeam with vertical outrigger. The floorbeam is connected to the diagonals and the interior lattice bar railings by a gusset plate. The flooring system consists of rolled stringers and plank deck.
