Design
Seated upon cut stone abutments and wingwalls, this single-span pin-connected Camelback is divided into seven panels by verticals of reverse channels laced to one another. The heaviness of the structure is evident in the crafting of the channels and the cover plates used for the endposts and top chord. Heavy diagonals (reversed laced channels) pinned midway into the endposts stabilize the abutment panels which are of different size to adjust for off-setting the south truss by about 6' to the west. The use of cylindrical and die-forged eyebars as diagonals in the three center section panels is reversed in the opposite truss: Double die-forged eyebars are countered with cylindrical ones with turnbuckles (doubled in the most central panel). The top chord for each of the two side panels has a different slope. The typical and yet heavier double die-forged eyebars angle from the top pins downwards towards midspan, although the panel close to the center section also has an adjustable counter. The heavy girder floor beams are riveted to the vertical above the lower chord. They, in turn, have heavy girder stringers riveted to the floor beams.
The bridge carries double tracks
