Almost a kilometre of London’s Oxford Street, a famous shopping area in the heart of the capital, is now pedestrian-only.
The first phase of the major overhaul is expected to be finished by spring 2027.
London Mayor Lord Sadiq Khan said the move marked the “end of decline” for the street.
“We will have a great lead up to Christmas, safe and spacious, and next year you’ll be seeing more trees and seats and public squares”, the mayor said.
BBC reporter Graham Satchell went to Oxford Street’s pedestrian-only section for a stroll.
