Royal Border Bridge
Royal Border Bridge spans the River Tweed between Berwick-upon-Tweed and Tweedmouth in Northumberland, England.
The bridge is a Grade I listed railway viaduct built between 1847 and 1850, when it was opened by Queen Victoria.
It was designed by Robert Stephenson and built for the York, Newcastle and Berwick Railway and is still in regular use today, as part of the East Coast Main Line.
The bridge is 2,162 ft (659 metres) long and constructed in stone except for brick soffits to the arches. It has 28 arches, each spanning 60 feet (18 m). The railway is carried 121 ft (37 m) above the river level.
In the 1990s it underwent significant repair work for the first time, in a Railtrack project with some funding from English Heritage.
