American Bridge was general contractor for the superstructure of this two-lane suspension bridge over the St. Lawrence River between New York and Canada. The bridge has a 2,150′ (655m) suspended span and a 1,150′ (350m) mainspan, two 243′ (74m) steel towers, and two 106′ (32m) steel cable bents. The superstructure is a steel truss 15′ (4.57m) deep by 36′ (11m) wide. The suspension system consists of two 11 3/4″ (286mm) cables made from 37 prefabricated bridge rope strands – 31 of 1 3/4″ (44mm) and 6 of 1 1/4″ (32mm). There were also three backstay ropes of 1 3/4″ (44mm). The cables were made round with aluminum filler and wrapped with number nine wire.
