Kingsgate bridge was commissioned by @Durham_Uni and was the last structure designed personally by Ove Arup @ArupGroup . It opened in 1963 and is Grade 1 listed. Fillinghams, a local photographic company captured the building of the bridge. See more here https://bit.ly/2Exn3QB 

@PalaceGreenLib we look after the photographs which have recently been digitised. Here are a selection showing construction of Kingsgate Bridge.
