Seven bridges span the River Tyne in and around Newcastle, three of them famous internationally for the revolutionary approach to bridge building that they enshrined.
The oldest is the High Level Bridge, a two-level steel structure almost 165 feet high and built to plans drawn up in 1849 by Robert Stephenson and opened by Queen Victoria.
The Swing Bridge, designed by Sir W. G. Armstrong and opened in 1876, stands on the same site as the "Pons Aelius" fort built by the Romans.
