February 23, 2017

The Canam Group bridge division recently delivered the first piece for the Portageville Railway Bridge, which crosses the Genesee River in New York. The piece is a bottom chord box section of an arch truss.

The piece weighed 93,500 pounds, measured 53 feet, 6 inches (16 metres) in length and with the shop bolted gusset plates, the height of the piece reached 11 feet, 4 inches (3.5 metres).

The box, that was welded and painted inside and outside, was shop fabricated using a progressive assembly procedure to properly meet the fabrication geometry and ensure proper field adjustment. Installation of the 3,900 tons of Canam steel components will be completed in summer 2017.
