Shelly Beach Overbridge modification, Auckland

Shelly Beach Overbridge is located on one of the busiest motorways in New Zealand on the southern approach to the Auckland Harbour Bridge. With over 100,000 vehicles passing below this bridge every day in each direction, increasing the span to accommodate motorway widening presented a unique challenge. Cutting the bridge in half and sliding onto a new pier, with infilling and strengthening of the bridge superstructure, provided a cost effective and robust solution to this challenge. This paper describes how the design concept for modifying the bridge was developed and successfully carried through to construction.
