The Canadian Pacific Railway’s "High Level Bridge" is a world renowned feat of engineering that has survived continuous heavy freight traffic for more then 100 years to stand the test of time.The bridge (called a viaduct by CPR bridge engineers) is the longest and highest bridge of its type in the world. There are similar bridges that are longer, or higher, but none have the combination of length-height shown by the Lethbridge structure. Started in 1908, the bridge was completed June 22, 1909 and officially opened on Nov 1, 1909 and cost a whopping $1,334,425.00 to build.
It is 5,327 feet (1,623 metres) in length (one mile plus 47 feet), and is 314 feet (95.7 metres) in height above the bed of the river. The West end is 21.31 feet higher than the East end. The east end is 3800 feet west of what was the Lethbridge Station.
The cache is about 600 metres from the parking lot at Elizabeth Hall Wetlands. The pathway is between a golf course and a waterway where you can see many varieties of water fowl and birds, as well as beavers and muskrats. As you walk along the path, you will come closer and closer to the bridge until you reach the cache site, which is only a few metres away from the huge structure.
