In this issue, we look at the engineered use of coated fabrics in long span roofs, consider strengthening techniques and also look at projects including the Armstrong Bridge, and Jesmond Dene Bridge.

This issue of the Arup Journal includes an historical study of Armstrong Bridge, a 19th century multi-span iron road bridge near Newcastle-upon-Tyne.
We explore the bridge's design and construction, and also look at the Jesmond Dene Bridge - a bridge that Arup was commissioned to design to replace the Armstrong Bridge - but which ultimately never came to be.
In other articles, we explore the use of coated fabrics in long span roofs, looking at a number of examples where Arup has utilised this approach, and also Poal Beckman considers strengthening techniques.
