The Pedway: Elevating London is a documentary on the post-war redevelopment in the City of London – focusing on the attempt to build an ambitious network of elevated walkways through the city. Featuring interviews with professor of town planning Michael Hebbert (UCL), architecture critic Jonathan Glancey, city planning officer Peter Wynne Rees and writer Nicholas Rudd-Jones (Pathways), the film explores why the ‘Pedway’ scheme was unsuccessful and captures the abandoned remains that, unknown to the public, still haunt the square mile.
