"...Not far from Mabey's headquarters in Chepstow is one of its most famous projects, the original Severn Bridge opened in 1966. This is where Adam has arranged to meet
Prof. David Blockley f
rom the Faculty of Engineering at the University of Bristol. As they stand on the old bridge and look towards the Second Severn Crossing, David tells Adam how to 'read' a bridge: the different structures engineers use, the forces at work in a bridge and how bridges can be beautiful as well as functional."
