Since the opening of the original truss bridge in 1959, and subsequent widening with the box girder extensions in 1969, the Auckland Harbour Bridge has been one of the most iconic and busiest bridge structures in New Zealand. It not only connects water, telecommunication, power and gas services; but also carries an average of 180,000 vehicles that travel over the Bridge each day. This makes it one of the country’s most vital infrastructure links, not only between the North Shore suburbs and the rest of Auckland City, but between the Northland Region and the rest of New Zealand.
