The Lethbridge train trestle bridge is the longest, highest railway structure of its kind in the world. It’s over one mile in length and more than 300 feet high. When it was completed in 1909 it was regarded as a wonder of the British Commonwealth. Known both as the High Level Bridge and as the Lethbridge Viaduct, it is now designated a National Historic Event.
Trains cross this trestle over the coulees surrounding the Oldman River every single day and have done so for more than a century. It’s a Canadian engineering feat that has withstood the fierce winds and freezing temperatures of the unpredictable Alberta winters, with not a single day of downtime.
“Bridges represent archetypal problems. They are artifacts that bring you across or around an obstacle. So they have an unbelievable force. “~ Santiago Calatrava
