Conisbrough Viaduct

You can walk across this and head down closer to the Rive Don. There is nice little path that leads all the way down to the village of Warmsworth.

When the route veers off the path under the viaduct be aware this is not a well kept, if at all, path and requires ducking under fallen trees and avoiding a marsh bed. If I did it again I’d continue along the paved path next to the viaduct as this rejoins the Komoot route further on.

Conisbrough Viaduct is a former railway viaduct, near to Cadeby and Conisbrough in South Yorkshire, England. The viaduct consists of two sections of brick and stone on each bank, connected by a lattice girder section, some 113–116 feet (34–35 m) over the River Don. The height and space were required should shipping need to navigate along the river. The viaduct carried the Dearne Valley Railway over the River Don between 1909 and 1966, after closure it was converted into a foot and cycle path. The structure is grade II listed,
and is notable for being one of the first bridges in Britain to be built using a rope system above the viaduct known as a "Blondin". en.m.wikipedia.org/wiki/Conisbrough_Viaduct
