The bridge was built by the Grand Trunk Railway (GTR) in 1909. It is now owned by the Canadian National Railway (CNR). The bridge was damaged in 2013 and has been closed to vehicular traffic since. [After a bunch of litigation, it opened again in 2019.]

"Originally, when the bridge was first opened, it was operated by a hand crank." [4:20]

The truss members use an interesting mix of lattice and plate fabrication techniques. And the members are connected with gussets instead of pins.
