The Viaduct was built by a contractor named Ambrose Crawshaw and work commenced in 1862. It has five 12.2 metre arches and is 84.1 metres long. The Viaduct’s highest point is 23.8 metres above the creek bed. Construction took several years and it is now the oldest existing stone archway over water in NSW still in use.
