Oxford Street will go car-free for one day as Sadiq Khan's pedestrianisation edge closer.
Vehicles will be prohibited from accessing a half-mile stretch of the road from Oxford Circus to Orchard Street between noon and 8pm for the event called This Is Oxford Street.
The road space will be used to accommodate activities and entertainment such as live music performances, art installations, food and drink stands and a literary festival.
Oxford Street is one of the world's busiest shopping areas, with around half a million visitors each day.
Sir Sadiq wants to ban vehicles from a 0.7-mile stretch between Oxford Circus and Marble Arch, which hosts around half a million visitors every day and has an estimated annual contribution of £25billion to London's economy.
