London's Unfinished Ringways and Railways

From Metafilter: London's Unfinished Ringways [and Railways]

Unfinished London's long awaited second episode is a wonderful DIY documentary about London's failed 'Ringways' road-building project, made and presented by Jay Foreman. The first episode, about a branch of London's underground that was never built, is also excellent (and much more fun that you might expect).
