Building the World's Tallest Bridge: The Millau Viaduct

Building the World's Tallest Bridge: The Millau Viaduct

Series 1



“I was almost physically sick with anxiety,” recalls Lord Foster of a site visit to the half-built Millau Viaduct in south-west France. He had led the design team on what would become “arguably the most beautiful bridge in the world”, according to presenter Rob Bell (no argument from me), but the building of it ran into problems along the way, including a landslide and undiscovered limestone caves under one of the towers.

Bell talks us through the mega-engineering and the stats – one-and-a-half miles long, the tallest bridge in the world and so on – but it’s the sheer elegance and sweep of the design that strikes you again and again.


At 343 metres, the Millau Viaduct over the Tarn gorge in southern France is the world's tallest bridge and considered by many to be the world's most beautiful. Engineer Rob Bell meets the design team, including architect Norman Foster and structural engineer Dr Michel Virlogeux, and learns about the innovative and ancient techniques used to build it. London's Millennium Bridge, Foster's pedestrian-only thoroughfare, is also featured, including what caused its infamous initial wobble and how it was rectified.
