Canadian Pacific Swing Bridge, Thunder Bay

This steel swing bridge in Thunder Bay, Ontario, carries the Canadian Pacific Railway line across the Kaministiquia River near the city’s grain terminals. Built in the early 20th century, the structure allowed both rail and maritime traffic to pass through the busy industrial waterfront—pivoting open for ships bound to and from Lake Superior. The bridge remains an important relic of Thunder Bay’s era as one of Canada’s foremost grain-shipping hubs, linking prairie rail lines to Great Lakes freighters and global export routes.
