This colossal structure crossing the Oldman River replaced the more circuitous original route over the St. Mary's River. The bridge was built by the CPR with 12,200 tons of steel and 17,090 cubic yards of concrete, among other materials.

As that was completed, it was rolled forward on the newly-constructed piece to begin the next section.
The traveller was built on site and placed the last girder in June 1909.
I suppose this method would require a lot of confidence in the bridge piece that you had just completed! (image at right from the Crowsnest Pass Railway Route site)
- Length: Lethbridge - 5,331' (1,624m); Salmon River - 3,920' (1,194m)
- Height: Lethbridge - 314' (95.7m); Salmon River - 195' (59.4m)
- Towers: Lethbridge - 33; Salmon River - 51
Lethbridge's towers are much wider than most (67' / 20m) and the spans between towers are also longer than most (97' / 30m).

I visited again in May 2016 and spent several hours around the bridge one beautiful evening. I parked in Heritage Heights and clambered down to the Oldman river. It's quite a long trip down!
The bridge is quite impressive from all angles. It's difficult to capture the entirety of the bridge without being very far off. I took a little break and just sat and took it in.

If you're ever in the area, I highly encourage you to check this bridge out. It's very impressive.
