Lambley viaduct crosses the River South Tyne as a series of elegant stone arches.

The railway, which was opened in 1852 to haul coal and lead from the Alston mines, closed in 1976, and the viaduct was allowed to decay.

[3][4] The viaduct was probably designed by George Barclay Bruce,[1] a Victorian engineer who was involved in the Alston line before leaving for India to pioneer railway construction there.

The spandrels and piers to the 6-metre (20 ft) wide approach arches are built of coursed rubble masonry.

[5] One end of the viaduct has been fenced off, after the path was diverted in 2004 to pass further away from Lambley railway station, which is now a private house.
