According to Wikipedia, “this bridge is a six-lane, Art Deco style, steel constructed in 1930-1932 in Vancouver, British Columbia…the bridge’s two close approach spans are Warren trusses placed below deck level, while its central span is a Pratt truss placed above deck level to allow greater clearance height for ships passing underneath. The central truss is hidden when crossing the bridge in either direction by vertical extensions of the bridge’s masonry piers into imposing towers, connected by overhead galleries.”
Busts of Captain George Vancouver and Sir Harry Burrard-Neale are carved above the ship prows that jut from the bridge’s superstructure. Click on the photo below to enlarge.
The towers with the lamps were made as part of a war memorial.
