Johnson Street Bridge 1,000 Tonne Bascule Pier Box Lowered into Downtown Victoria's Harbour

Watch a time-lapse video of the new Johnson Street Bridge's 1,000 tonne bascule pier box lower into Victoria's downtown harbour. It took 37 hours over four days to slowly lower the bascule pier box into five metres of water. The temporary underwater structure will allow the new bascule pier to be constructed in the harbour under dry conditions. The new bascule pier will serve as the housing to support the mechanical and electrical systems that move the bascule leaf to open and close the new bridge.
