The Mayor and TfL are giving people across London the opportunity to make the most of traffic free streets on World Car Free Day, to play, meet, walk, cycle and enjoy. Around 50 streets across London from Hackney to Ealing will be traffic free on 22 September to help encourage people to ditch their cars and reclaim streets from traffic, which will open up spaces to the whole community. By supporting London Play, a charity that works to give children the freedom to play by shutting roads to traffic, streets across the capital will be traffic free for the day. Play streets, where roads are regularly shut to traffic for a few hours each week or month offer more than just a safe space for children to play outside with their friends, they also encourage a sense of community, as well as making sure streets feel friendlier and safer. London Play has been working to transform streets into safe, fun places for children since 2008. Poor air quality is estimated to contribute to more than 40,000 premature deaths across the country each year, with emissions from cars and vans estimated to cost £6bn annually. Supporting streets without cars is part of the Mayor and TfL's efforts to make London's communities greener, healthier and more attractive places to live, work, play and do business. Heidi Alexander, Deputy Mayor for Transport, said: 'I'm delighted that Londoners will be able to enjoy more than 40 streets without traffic noise and exhaust fumes on World Car Free Day. 'Our support for London Play will transform neighbourhoods for families and offer a valuable opportunity to inspire long-term change, helping build on our work to reduce reliance on cars and clean up the capital's dangerously polluted air.'
