France: A footbridge constructed using LafargeHolcim's Ductal® concrete for the Pont du Diable

24 April 2009

Each year the Pont du Diable is crossed by more than 250,000 walkers who come to visit the gorges of the Hérault in France, a UNESCO World Heritage Site.


Designed by architect Rudy Ricciotti and engineer Romain Ricciotti to handle this high level of traffic, the Pont du Diable footbridge is an innovative construction thanks to LafargeHolcim's Ductal® ultra-high performance concrete:

  • the footbridge spans more than 70m reaching a static height of 1.80m, without any intermediary support, arches or stays,
  • it comprises 15 prefabricated concrete sections, without any steels,
  • the fluidity and superior mechanical performance of Ductal® meant the bridge deck needed to be just 4cm thick, a technical performance never before seen for a construction of this size!

Ductal®'s discretion, performance and lightness also allow the Pont du Diable footbridge to blend seamlessly into this typical southern French landscape.
