The next step of Jonathan's journey takes him to the Clifton Suspension Bridge in Bristol. Begun in 1835 by the great engineer Isambard Kingdom Brunel when he was only 24 years old, it's one of the greatest feat of Victorian engineering in the world.

With unprecedented access to the bridge, aided by champion climber Lucy Creamer, Jonathan scales all over to the bridge to investigate the innovations and techniques used to build this incredible structure inspired by £1000 from a wine importer.
