The Tom 'Diver' Derrick Bridge, commonly referred to as the 'Diver' Derrick Bridge, is an opening single-leaf bascule bridge over the Port River, Port Adelaide. It was opened for traffic on August 3rd 2008. The entire bridge project cost approximately $178 million. It is located between Docks 1 and 2 at Port Adelaide and links to Francis Street to the east and Victoria Road to the west. It has been built at the same time as a rail bridge, the Mary MacKillop Bridge, which is located right next to it.
The bridge was the subject of a successful community campaign, spearheaded by the local RSL and the Portside Messenger newspaper, to name it after Port Adelaide World War II hero, Tom 'Diver' Derrick VC, DCM instead of the State Government's unpopular choice of the 'Power Bridge'.
The road and rail bridges were originally referred to as the PRExy Bridges, short for Port River Expressway. In 2004, South Australian Premier Mike Rann announced the road crossing would be named the 'Power Bridge' after the Port Adelaide Football Club which had recently won the AFL premiership. The State Government later announced it would hold a public competition to name the second bridge. But in 2005, in the wake of the death of Pope John Paul II, Mr Rann announced the rail bridge would be named after beatified Catholic Sister Mary MacKillop.
Later in 2005, it was suggested the bridge be named after Derrick. This idea gradually garnered grassroots support in Port Adelaide. In May 2008, the Portside Messenger collected a 3500-signature petition in support of the Derrick name. Port Adelaide-Enfield Council also unanimously supported naming the bridge after Derrick.
On June 5, 2008, the State Government announced it had changed its mind and would name the bridge after Derrick. The Port Adelaide Football Club agreed to relinquish its naming rights to the bridge.
