The Harwood Bridge, which carries the Pacific Highway traffic between Sydney and Brisbane, opened in 1966 and is of historic significance. It replaced the last vehicular ferry on the New South Wales State Highway system and was the last and longest steel truss bridge built by the Department of Main Roads (DMR). Its construction also signified the first town by-pass on the State Highway System built by the DMR, that being Maclean.
It has a vertical lift span to allow boats to pass underneath. It's operated by lowering the huge concrete blocks at the top of the towers and therefore raising one span of the bridge. This is all carried out in the little house on top of the span.
