The American Bridge Company of New York fabricated this single-span, pin-connected Pratt through truss which is approached with a timber bent causeway to the north. The whole is seated upon concrete abutments and wingwalls. The endposts and top chords are manufactured from heavy crafted channels and cover plate. Laced heavy channel or crafted channel verticals subdivide the through truss into seven panels. Eyebars provide the diagonals: two pairs of die-forged and rectangular ones stretch toward center span from the top panel point to the bottom of the 2nd and 6th panels and a pair of the 3rd and 5th panels; cylindrical eyebars with turnbuckles counter the others in the 3rd and 5th panels and pairs cross the 4th or center panel. Riveted to verticals above the lower chord, girder floor beams carry the timber tie and single track deck.
ALTERATIONS: The bridge has a single track deck, but the bridge was built to accommodate two tracks.
