Royal Border Bridge

Royal Border Bridge spans the River Tweed between Berwick-upon-Tweed and Tweedmouth in Northumberland, England. It is a Grade I listed railway viaduct built between 1847 and 1850, when it was opened by Queen Victoria. The engineer who designed it was Robert Stephenson (son of George Stephenson). It was built for the York, Newcastle and Berwick Railway and is still in regular use today, as part of the East Coast Main Line. Despite its name, the bridge does not in fact span the border between England and Scotland, which is approximately three miles further north.The bridge is long and constructed in stone except for brick soffits to the arches. It has 28 arches, each spanning. The railway is carried above the river level.Repairs and modificationsIt was electrified in 1989, and between 1993 and 1996 it underwent significant repair work for the first time in a Railtrack project with some funding from English Heritage.
