The project, which begins on April 28, will see the area between Pump House Lane and Vauxhall Gyratory transformed with new cycle tracks, bus stops, wider footways, and improved pedestrian crossings.
The work is part of a broader effort to make Nine Elms Lane and Battersea Park Road safer and more accessible for pedestrians and cyclists.
TfL also plans to plant new trees, provide more cycle stands and benches, and improve drainage facilities.
The construction work is expected to be completed by autumn 2026.
The first phase of the scheme, which opened in August 2021, was between Duchess Bridge and Sleaford Street.
The improvements are based on a public consultation in 2017 and ongoing engagement with local residents, developers, businesses, Wandsworth Council, and the Nine Elms Vauxhall Partnership.
The enhancements will include 1.6km of continuous cycleways in each direction, additional and improved pedestrian crossings, and wider footways.
There will also be improved signal-controlled junctions to facilitate improvements for cyclists and pedestrians, and improved bus stops with new bus shelters providing equal access for all bus users in line with TfL guidelines.
The existing drainage systems will be improved, with new sustainable drainage helping the road to adapt to climate change.
Twenty-four new trees will be planted, and all pavements and the road will be resurfaced.
The work will take place between 8am and 6pm from Monday to Saturday, with a limited amount of Sunday and nighttime working required for activities such as works to traffic signals and carriageway resurfacing.
To carry out the work safely, a number of changes to traffic movements will be required, including lane closures and the narrowing of the road to one lane in each direction.
During the lane closures, there will be temporary banned right turns in to and out of all side and access roads.
A banned left turn from Wandsworth Road into Nine Elms Lane will also be in place.
Cringle Street will be restricted to southbound traffic between Kirtling Street and Battersea Park Road.
Temporary traffic management arrangements will be in place 24 hours a day, seven days a week during the main phases of the works.
TfL aims to keep disruption to a minimum but warns that journey times may increase slightly during the works.
Bus stops will remain open and access to homes and businesses will be maintained.
At some stages of the works, bus stops and pedestrian crossings will be moved to nearby temporary locations.
Temporary cycle lanes will also be provided where possible.
The Walking and Cycling Commissioner, Will Norman, said: “Making London’s roads safer is a key priority for the Mayor, and is vital to enabling more people to choose walking and cycling.
“That’s why I’m delighted that the second phase of work to improve safety and accessibility in Nine Elms will begin at the end of this month.
“These important improvements will ensure everyone living in and visiting the area can travel safely and sustainably, while supporting the regeneration of Nine Elms, building a better, greener, safer London for all.”
Julie Lewington, head of projects and programmes at TfL, said: “We are committed to ensuring the capital’s transport network is safe and reliable for the next generation of Londoners.
“These works to transform Nine Elms Lane and Battersea Park Road are a significant step in the regeneration of the area and will improve accessibility and safety for the thousands of people already cycling in this busy location, as well as those who want to walk and cycle more, but don’t feel safe.
“We’d like to thank local residents for their patience while these works are taking place.
“Roads in the surrounding area are expected to be busier than usual so please plan ahead and check before you travel.”
