Lethbridge Viaduct

The Lethbridge Viaduct, affectionately known as the High Level Bridge, is a masterpiece of early 20th-century engineering and an enduring symbol of Lethbridge’s history. Completed in 1909, this steel trestle bridge spans an impressive 1.6 kilometres (5,327 feet) and stands 96 metres (314 feet) above the Oldman River valley, making it the longest and highest bridge of its type in the world. Originally constructed to support the Canadian Pacific Railway’s expansion, the bridge played a pivotal role in connecting southern Alberta to the rest of Canada. Its remarkable design, with over 12,400 tonnes of steel, reflects the ingenuity and ambition of its time. Today, the High Level Bridge is not only a vital piece of infrastructure but also a popular landmark for visitors and photographers, offering stunning views of the surrounding coulees and the Oldman River below. Whether you admire its towering presence from the river valley or capture its silhouette against a fiery prairie sunset, the High Level Bridge remains a must-see attraction that celebrates both the past and the spirit of progress.
