Crews are currently constructing temporary work areas that will support the large cranes, equipment and crews building the new bridge.
Two work platforms are now visible on the east and west sides of the existing bridge.
Crews are currently constructing the foundation of a temporary work trestle that will extend from the downtown side of the bridge into the Upper Harbour. To build the foundation, long steel pipes (also known as piles) are pushed down into the harbour bed. The piles are then cleaned to remove silt and then drilled into the bedrock.
Once all the piles are in place they are cut to a specific height and a flat surface is added to the top.
Next, a platform will be built for the trestle which will connect to a construction access road on the east side of the harbour for loading cranes and equipment to build the new bridge.
Construction of the work trestle will continue into September. Once complete, the next activity will be the construction of the new bridge foundation. This work is expected to continue in the harbour until February 2014.
The current bridge will remain open to pedestrians, cyclists, vehicles, and marine traffic until the new bridge opens in late 2015. Full project completion, including removal of the rail bridge, landscaping, and installation of public art is expected by March 2016.
