The Red Bridge in Tasmania crosses the Elizabeth River at Campbell Town. It was built between 1836 and 1838 by convicts using red clay bricks made on site. It has a solid stone base with sandstone piers and cappings. It is the oldest brick arch bridge in Australia, as well as the oldest bridge anywhere on an Australian National Highway. The bridge has three arches with spans of each. It is wide enough for two lanes of traffic as well as pedestrian walkways. It is on the Midland Highway, about halfway between Hobart and Launceston, and carries over two million vehicles per year.
