The bridge is 703.5 feet long and 12 feet wide. It contains one 200-foot Camelback through
truss, one 110-foot Pratt deck truss, one 20.5-foot bent, one 66-foot Pratt half-hip deck truss,
five steel I-beams (from 19-25 feet long), and one 200-foot approach on masonry fill. All
trusses are pin-connected. Composition of the Camelback truss is typical. Top chords and
end posts are channels. Bottom chords and diagonals are paired rectilinear eyebars. Verticals
are small channels with lacing except hip verticals which are paired rectilinear tie rods.
Counters are paired cylindrical tie rods. Composition of the Pratt trusses is less typical but
not unique. Top chords and end posts are paired angles with lacing top and bottom, and
bottom chords are paired rectilinear eyebars. Verticals are paired angles with lacing. Diagonals
in the end panels are paired rectilinear eyebars. Diagonals in the center panels and all
counters are single cylindrical tie rods. The Camelback truss rests on a small masonry
abutment on top of a stone bluff and a pier of steel encased concrete tubular cylinders; the
remainder of the substructure is steel bents. The steel bent eastern approach contains a sharp
