Kilton Viaduct was a railway viaduct that straddled Kilton Beck, near to Loftus, in North Yorkshire, England. The viaduct was opened to traffic in 1867, however in 1911, with the viaduct suffering subsidence from the nearby ironstone mining, the whole structure was encased in waste material from the mines creating an embankment which re-opened fully to traffic in 1913. The railway closed in 1963, but then in 1974, it re-opened as part of the freight line to Boulby Mine carrying potash traffic.

Saltburn Viaduct is a railway bridge in Redcar and Cleveland, North Yorkshire, England. The line was built as an extension of the Redcar and Saltburn Railway, and the viaduct is mostly built out of brick. The line opened to passengers in 1872, but became freight only in 1957, a purpose for which it still is in use for today as part of the Boulby line.
