Dunham Bridge is a toll bridge across the River Trent in England. It spans the border between the administrative counties of Nottinghamshire and Lincolnshire to the west and east respectively. It forms part of the A57 road, in the section between the Great North Road and Lincoln. It takes its name from the nearby village of Dunham-on-Trent. ==History== Until the bridge was built and opened in 1832, the crossing of the river was by Dunham Ferry. In 1814, the fare was reported at half a crown.〔Letters from England, Volume 2. Robert Southey. 1814〕 The bridge was established in the 1830s, under the powers of the ''Dunham Bridge Act 1830'', when a group of local businessmen built the original cast iron construction.〔(【引用サイトリンク】work=Dunham Bridge Company )〕 It was a four-span cast-iron structure by the civil engineer, George Leather (1786-1870).〔A biographical dictionary of civil engineers in Great Britain and Ireland.
