Around 27km of London's streets will go car-free for one day this September.
Last year, 27 of the 32 boroughs took part in London's Car Free Day, with major thoroughfares — including Tower Bridge, London Bridge and much of the City of London — closed either to cars, or all motorised vehicles.
London's 2020 event, held on Sunday 20 September, promises similar, with hundreds of 'play streets' opening up across the city, allowing children to enjoy themselves safely outside their homes and in their local communities.
Londoners will be encouraged to walk, cycle or take public transport on the day, and as luck would have it, this year's event coincides with Open House Weekend — so it might be easier for you to hop, skip and jump from venue to venue, or to join a walking tour.
The serious message of London's Car Free Day, of course, is that the city is suffering from the effects of air pollution; two million Londoners live in areas exceeding legal limits for nitrogen dioxide (NO2), including more than 400,000 children.
Mayor of London, Sadiq Khan has a target of 80% of all journeys in London to be taken by sustainable modes of transport by 2041. (Currently it's 63%.) Said Khan: "I'm determined to make this year's event even bigger and better and I look forward to revealing more plans in the summer."
London goes 'car-free' on 20 September, although World Car Free Day itself is on 22 September.
