Lambley Viaduct

Lambley Viaduct is a stone bridge across the River South Tyne at Lambley in Northumberland. Formerly a railway bridge, it remains open to pedestrians but one end of the viaduct has been fenced off.

History
Lambley viaduct crosses the River South Tyne as a series of elegant stone arches. More than 260 m long, it once carried the Haltwhistle to Alston railway. 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. In 1991 the British Rail Property Board agreed to repair the viaduct and hand it over to the North Pennine Heritage Trust which would maintain it in the future; however the Trust went into administration in 2011.

The viaduct was probably designed by George Barclay Bruce, a Victorian engineer who was involved in the Alston line before leaving for India to pioneer railway construction there. It is a particularly elegant example of Victorian engineering: the river is crossed by nine 17 m wide arches which support a deck at least 33 m above the river but, as it carried a single rail track, only 3.5 m wide. The piers to the arches are built of massive rough-faced stones each weighing up to 500 kg, with similar-sized stones in ashlar to the main arch voussoirs. The spandrels and piers to the 6 m wide approach arches are built of coursed rubble masonry.

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.

It is a Grade II* listed structure.
