Within the “Pont de Normandie” consortium, Bouygues Travaux Publics built what was when it opened in 1995 the world’s largest cable-stayed bridge in France. It has a total length of 2,141 metres and a span of 856 metres, crossing the River Seine at a height of over 50 metres in order to keep the road traffic flowing without interfering with river traffic heading towards Rouen. In 1995, the 856-metre central span raised the world record for such a span by 80%. For Bouygues Construction, this project provided the opportunity to patent a construction method developed in-house, which proved itself capable of pushing a 700-metre deck up a stepped 6% incline.
