Gananoque River Bridge
The Gananoque River Bridge is a railway bridge across the Gananoque River located between Montreal and Toronto at mile 155.9 in CN Rail's Kingston subdivision. It consists of four identical spans carrying single track supported on common piers and abutments and was built in 1902–1903 according to Grand Trunk Railroad specifications of 1900.
== Technical details ==
Each span has a total length of 20.091 m and is composed of two plate girders with a depth of 1.69 m each with a 2.134 m spacing. The entire bridge structure is riveted with 22.2 mm (0.875 in.) rivets. The bridge is made of an open hearth-type steel which closely resembles today's mild steel (ASTM A36 steel).
A single railway track is located symmetrically on top of the girder flanges. The 132 lb type rails are supported by timber railway ties (250 x 250 mm) in section with a 356 mm spacing.
A 1991 engineering study showed "no major structural deficiency of the bridge superstructure in terms of excessive stresses or deflections under normal traffic conditions". Tests indicated that the static strength of the bridge sufficient to allow trains running at speeds not exceeding 96 km/h (60 mph).
