Montreal Clock Tower

Powerscourt Covered Bridge National Historic Site of Canada is a remarkable structure located in Elgin Township, Huntingdon County, Quebec, recognized for its rich heritage and architectural significance. Built in 1861, it stands as the only remaining McCallum inflexible arched truss bridge in the world and one of the oldest covered bridges still existing in Canada.

The bridge, which carries traffic over the Châteauguay River, showcases historical construction technology that was primarily utilized for railway systems, invented by Daniel McCallum in 1851. Its heritage value stems not only from its unique design and age but also from its well-preserved state, capturing the essence of 19th-century engineering and craftsmanship.
