In 1766 ‘Wandesford’s’ or Clarke’s Bridge was built over the south channel to connect Wandesford’s Quay and Clarke’s Marsh with the city. Clarke’s Bridge is the only surviving 18th-century bridge within the city whose building stone, including its voussoirs, is predominantly of local red sandstone. It is reputed to have had one of the longest spans of any Irish, single span, segmental arch bridge built during this time.
