Alston Arches Viaduct, also known as Haltwhistle Viaduct,[2] is a stone bridge across the River South Tyne at Haltwhistle in Northumberland, England.
The bridge, which has four stone arches, was designed by Sir George Barclay Bruce as a railway bridge.[3][1]
It formed part of the Alston Line and was completed in March 1851.[2] The railway closed in May 1976[2] and the bridge was re-opened by the Duke of Gloucester for pedestrian use in July 2006.[4] It is a Grade II listed structure.[3]
