The document discusses the history and need to replace the Old Mangere Bridge in New Zealand. It describes how the original bridge opened in 1875 but was narrow and prone to shipworm attacks. The current bridge was built in 1915 but closed to traffic in 1983 when a new motorway crossing opened. The document also provides examples of impressive bridges from around the world and discusses different types of bridges such as truss, arch, cable-stayed, and suspension bridges.
