Over Bridge, also known as Telford's Bridge, is a single span stone arch bridge spanning the canalised West Channel of the River Severn near Gloucester. It links Over to Alney Island. Although there was a crossing at Over recorded in the Domesday Book, this famous bridge was built by Thomas Telford between 1825 and 1828, to carry traffic east-west. It was opened in 1830 and remained in use for traffic until 1974. Until the Severn Bridge was built in the 1960s this was the lowest point downstream that the Severn could be crossed by road bridge.
