This is a south-easterly view over the Don valley from the western end of the Conisbrough viaduct near Doncaster, South Yorkshire.

The viaduct was built in 1906-07 to carry the Dearne Valley Railway across the Don valley, thus connecting the Lancashire and Yorkshire Railway with the Great Northern and Great Eastern Railways. It is 528 yards in length with 14 arches on one bank and 7 on the other connected by an iron girder bridge 115 feet above the River Don. The last passenger train ran across the viaduct in 1951. It is now used as an impressive footpath and cycle track.
