Work to increase cyclist and pedestrian safety at Waterloo roundabout will start in early 2020.
The work will deliver “dramatic changes” including the introduction of segregated cycle lanes, wider footpaths and a full redesign of “the intimidating” junction.
Transport for London says the scheme has been designed in light of research showing safety concerns are a major barrier to more people cycling in the area.
Will Norman, London’s Walking and Cycling Commissioner, said: “Waterloo roundabout is currently one of the most dangerous junctions in London, so it’s great news that we can progress with our plans to improve it.
“We’re going to transform this intimidating junction, making it safer and more pleasant for all those who use the area.
“By creating people-friendly streets, we can encourage many more Londoners to walk, cycle and use public transport, improving our health and air quality.”
Leon Daniels, Managing Director of Surface Transport, added: “I’m extremely pleased that by working with the local community and business groups we’re able to confirm work will start in early 2020 at Waterloo Roundabout and Waterloo Road – but that we’re also continuing to work with the community to ensure the work meets their needs.
“Projects like this can help create a better London less dependent on the car, where public health is improved, the creation of new homes and jobs are supported and where everyone can travel in a healthy, affordable and accessible way.”
The work is being delivered by TfL and Lambeth council.
Cllr Matthew Bennett, the borough’s Cabinet Member for Planning, Regeneration & Jobs, said: “We are determined in Lambeth to make our streets safer, cleaner and easier for everyone to get around, particularly those who walk or cycle, so we’re pleased to be working with TfL on such a major project, investing to improve the area around Waterloo roundabout and along Waterloo Road.
“We want the area to be a more attractive place for people to spend time in, use local businesses and enjoy everything that is on offer.
“I’m glad so many people took part in the consultation and I’m confident these plans will make Waterloo a much better, healthier and safer place to live, work, and visit for years to come.
“We are also committed to continuing to work with local residents in the area to reduce rat running and congestion in neighbouring residential roads.”
