Roads around the Old Street roundabout will be switched to their final layout this weekend, allowing the overhaul of the neighbouring Tube station and surrounding area to move to the next phase.
London Underground says the project will improve journeys for the millions of people using Old Street station each year while also “significantly” improving safety for cyclists and other road users.
The scheme will also create a major new public space with better access to the station.
From 05:00 on Monday 18 January, the right turn from Old Street west into City Road south will be permanently banned along with the right turn from Mallow Street into Old Street and Old Street west and City Road south will reopen to traffic.
This layout is the same as the permanent, final layout of the completed roundabout, though not all traffic and cycle lanes will be available straight away.
TfL says it’s working closely with its contractors and Islington Council to complete the transformation work as quickly as possible, with plans to finish work by autumn 2022.
Will Norman, London’s Walking and Cycling Commissioner, said: “Old Street is one of the busiest junctions in London in normal times so I’m really pleased that we have reached the significant milestone of switching roads to the final layout, and remain on track to complete the transformation by autumn next year.
“It’s more important than ever that we make our roads safer for people walking and cycling to avoid a car-led recovery from the pandemic.”
Nick Fairholme, TfL’s Director of Project and Programme Delivery, added: “Our work to transform Old Street station and roundabout will make a huge difference to everyone who travels through the area.
“The project includes extensive improvements to the station and will create a significantly more attractive environment that is much safer for cycling and walking.
“The next phase of the project will affect how some people travel through the area and I’d advise people to check their journeys before they travel to avoid delays. I’d also like to thank everybody in the area for their patience while construction work continues.”
