Tasmania Richmond Bridge Originally named Bigge's Bridge, Richmond Bridge is Australia's oldest bridge still in use. It was built by convicts from sandstone quarried at Butchers Hill and hauled by hand carts to the bridge site.
The Red Bridge in Tasmania crosses the Elizabeth River at Campbell Town. Built in 1838 using penal labour, it is the oldest surviving brick arch bridge in Australia, as well as the oldest bridge anywhere on the National Highway. The bridge contains three arch spans of 7.6 m (25 ft) each and holds two lanes of traffic as well as pedestrian walkways. It lies on the Midland Highway, roughly halfway between Hobart and Launceston, carrying over two million vehicles per year.
