Royal Border Bridge spans the River Tweed between Berwick-upon-Tweed (the northernmost town in England) 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 the famous 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.
The bridge is 659 metres long. It has 28 arches (not all arches visible here), constructed of brick but aesthetically faced with stone. The bridge is 38 metres above the river itself. In the 1990s it underwent significant repair work for the first time.
