Traffic will be banned from Oxford Street
The pedestrianisation has been approved
Plans to ban traffic from part of Oxford Street have been approved
The Mayor of London has announced that vehicles will be prohibited from accessing a 0.7 mile stretch between Oxford Circus and Marble Arch.
It's one of the busiest shopping areas, with around half a million visitors each day.
Sir Sadiq said: "I am delighted to be moving forward with my bold vision to transform Oxford Street into a world-leading urban space for shopping, leisure and outdoor events.
"Following TfL's (Transport for London) detailed consultation, I've today made the decision to move ahead with these exciting changes to the nation's high street.
"We will outline more details in the coming days, as we continue building a better, more prosperous London for everyone."
Works to pedestrianise the road are expected to start in the summer, with the first traffic-free section introduced by the end of the year.
Alex Williams, chief customer and strategy officer at TfL, said: "We will work closely with Westminster Council in the coming months to implement changes to the roads around Oxford Street, and the Mayor will provide more information on the next steps for this transformational scheme next week."
The Mayor's office said the plans received "extensive support from the business community" during a consultation by TfL.
Scott Parsons, chair of the newly created Oxford Street Development Corporation, said: "This is an exciting step towards creating a vibrant, new Oxford Street for Londoners, visitors and businesses alike.
"We're grateful to everyone who participated in TfL's consultation, which will help shape the future of one of the world's most iconic high streets."
Steve Gooding, director of motoring research charity the RAC Foundation, said: "In densely developed and historic cities like London there will always be keen competition for the limited road space available, resulting in contentious political decisions as to who gets priority.
"Perhaps the biggest traffic challenges with the Mayor's initiative is how to re-route the myriad bus services that will be affected, and deal with the junctions where road traffic currently traverses Oxford Street."
A previous attempt by Sir Sadiq to pedestrianise part of Oxford Street was blocked by then-Conservative-run Westminster City Council in 2018.
To succeed with his latest plan, he obtained permission from the Government to establish a new Mayoral Development Corporation - which provides planning powers - while TfL took over control of the road from the council.
