After the Blitz left the City of London in ruins, planners saw a chance to rebuild the capital on two levels, with pedestrians lifted above traffic on a network of elevated walkways called the Pedway. This film traces that scheme through surviving fragments: concrete bridges that dead-end mid-air, stairways that lead nowhere, walkways stitched onto office blocks and now half-forgotten by the people who walk beneath them. Architects, planners, and historians explain how the postwar vision of a fully separated pedestrian city was meant to fit together, and why only a patchwork of it ever got built, undone by piecemeal development, funding gaps, and shifting priorities across different eras of the City's reconstruction. Present-day footage follows the surviving sections on foot, matching them against old plans and drawings to show what was intended versus what actually exists. The film treats the Pedway as a monument to a future London never finished, and asks what these orphaned bridges and walkways say about how cities plan, and fail to plan, for the long term.
