AUCKLAND HARBOUR BRIDGE - SOUND

The Auckland Harbour Bridge, nine years old, is undergoing an expansion to double its capacity. Japanese cranes are used to add two new lanes on each side, effectively creating two additional bridges. The new spans are supported by existing piers but not connected to the current structure.
