Cisco Bridges, Two railway bridges in Siska, Canada.
Cisco Bridges are two parallel railway bridges crossing the Fraser River near Siska in British Columbia, each owned and operated by a different company: Canadian National Railway and Canadian Pacific Railway. The two structures run so close together that trains on both lines can cross the river at the same time, on separate tracks.
The Canadian Pacific Railway bridge was built around 1900, with parts shipped from England, and was at the time one of the longest cantilever span bridges in North America. A second bridge for Canadian National Railway was later added alongside it, turning this narrow river valley into a key rail corridor for western Canada.
Rail enthusiasts stop here regularly to photograph trains from both companies crossing side by side, which is a rare sight anywhere in the world. The spot has become a meeting point for people who follow train movements and document railway operations in the field.
Several pullouts along the Trans-Canada Highway give open views of both bridges without needing to step onto railway property. Stopping for a short while usually rewards visitors with at least one passing train, since the lines are in regular use.
The Canadian Pacific bridge connects directly into the Cantilever Bar Tunnel, which was carved through Cisco Bluff, so the train passes from open bridge to tunnel without any gap. This early design from around 1900 combines two different engineering methods into one continuous crossing through the rock.
