For more than fifty years before the Severn Railway Bridge was opened, there had been discussion and various proposals for rail routes to cross the Severn downstream of Gloucester, either by a bridge or a tunnel, but most of these did not leave the drawing board. The exception was a tunnel near Newnham on Severn in 1810; this had been excavated partway under the river when water broke in, and the tunnellers were lucky to escape with their lives. The damage was irreparable and the project abandoned. In 1845, an ambitious project by Isambard Kingdom Brunel was to bridge the Severn near Awre for his projected South Wales Railway, bypassing Gloucester completely. This plan got as far as receiving the approval of Parliament but did not proceed. Other schemes were mooted and in 1871, six different schemes were under consideration. Finally the Severn Bridge Railway's scheme was approved by Parliament and received Royal Assent on 18 July 1872.
