Jack Ryan, a 29-year-old marketing manager, was believed to be jogging on the bridge when he was struck by a Range Rover at the junction between Battersea Bridge and Beaufort St/Cheyne Walk.
Ryan’s death sparked a petition by Rob McGibbon that urged TfL to improve pedestrian access on the north junction with a pedestrian timer for the lights.
McGibbon said: “I feel no sense of celebration now that the crossing has been installed because it came out of such an appalling tragedy.
“I am pleased that everyone pulled together to help make it happen.
McGibbon’s petition was signed by over 26,000 people.
“I am particularly grateful to Transport Commissioner Andy Byford and his team for making this crossing possible in such a relatively short time,” he added.
Nick Fairholme, TfL’s Director of Project and Programme Delivery, said: “I’d like to thank local safety campaigners and the local community for working with us to develop this proposal and would also like to thank people in the area for their patience while construction work took place.”
Transport for London added new signals for a pedestrian crossing on the north side of the bridge and widened the pavement on both sides.
The improvements also increased accessibility with new a pavement specifically designed to help those with visual impairments.
Driving rules on the bridge have also been tightened.
The speed limit has been permanently reduced from 30mph to 20mph and the ban on right turns from Cheyne Walk to Battersea Bridge Road applies 24 hours a day.
Royal Borough of Kensington and Chelsea Councillor Johnny Thalassites said: “We needed this crossing badly and it’s a relief that it is now built.
“I’m grateful to the residents and campaigners who played a crucial role in making this happen and we’ve been right behind them every step of the way.”
