The new US$92.8 million stucture will be one of the largest single-leaf bascule lift bridges in the world. It has been designed by Wilkinson Eyre and MMM Group.

The new rolling bascule bridge will include cycle lanes and a pedestrian pathway and will feature new plaza areas for the public to view the harbour. It will be built to withstand an 8.5 magnitude earthquake.

PCL had been named as preferred bidder in November 2012.
