Police have increased patrols at at road works site in Sutton after careless drivers were spotted risking lives by jumping lights.

The 150-year-old London Road Bridge is currently being replaced in a £4m scheme funded by Transport for London.

Council contractors are operating an alternate one-way system controlled by temporary traffic lights across the bridge.

However, a council spokesman said a minority of “irresponsible motorists” are ignoring the lights and have narrowly avoided major accidents.

He said police have increased patrols in the area and have vowed to take appropriate enforcement action if they witness anyone driving dangerously.

Executive member for Environment on Sutton Council, Councillor Colin Hall, said: “This is essential repair work that will improve access to and from Hackbridge and we do apologise to residents and motorists for any disruption caused.

“However, that is no excuse for the ridiculous driving of a minority of drivers who are putting lives at risk to save a minute or two on their journeys.

“We have asked the police to step up enforcement in the area.

"I appeal to motorists to please be patient and warn those that break the law that they risk a hefty punishment.”
