If the London Box had gone ahead half of Brixton would have been demolished and for various contingent reasons I’d never have been born.
London's Ringways are a whole network of unbuilt urban motorways threaded through the capital. There's never been a complete map of them,not even one made by their designers, until now. Today we're publishing the Ringways Map from @roads.org.uk to let you see in the city that London nearly became.

dfl.london.gov.uk/library is a cool evolution of the London Datastore - allowing teams to signal what data exists, even if it’s not ready to share or to release in full. That visibility helps others discover, understand, and plan around the city’s data assets.
