An interesting read. This is in the southern end of the province I live in.

  To add

  The Lethbridge Historical Society has published two books on the Bridge. The first has a selection of construction
progress photos, the second is a reprint of the talk given to the Canadian Society of Civil Engineers  in 1909, with a series of plans for components of the bridge.

It's cool that something that was built in 1909 is still in use and able to handle today's railroad equipment. The fact that they had the design figured out back then and it didn't need upgrading is impressive. I know there are others around of the same design. It's just a salute to the engineering back then.
