Today was the official opening of a new bridge at Port Adelaide. In the afternoon the public were allowed the walk across the bridge, and at 4 pm the bridge opened to allow a large yacht to pass through.
As you can see in the photo there are in fact two bridges; the other one is a rail bridge.
The road bridge which cost 178 million dollars is named after a Port Adelaide World War II hero Tom "Diver" Derrick VC, who swam in the Port River.
People in attendance on the day were handed an A4 sized poster as a memento.
