The introduction of no overtaking lines in Harvil Road, Harefield, has been delayed.
It was agreed that the double white lines would be painted along the notorious road after a driver who was involved in a car accident along it campaigned for them.
Ian Sephton, who lives in Harefield, raised concerns with Hillingdon Council after a car which was coming towards him overtook the car in front and crashed into his car.
In March, the council confirmed the lines would be installed from the start of the 50mph speed limit at the Ickenham end of the road, to just before the bridge at Skip Lane.
In an email from the council’s Transports and Projects team, Mr Sephton was told “the road markings will be installed as soon as feasibly possible”.
But five months on, they are still not there.
The council now says some ‘concerns have been raised’ by staff in the road marking team about the proposed lines, which need to be resolved.
What these are is unclear.
Mr Sephton called the situation a ‘nightmare’.
He decided to lobby the council because he said he ‘could not have lived with himself’ if he had not done anything following the accident.
He says he can’t wait for the work to be completed.
Bar maid Louise Clark, of Ickenham, died in 2012 following a crash at the Ickenham end of the road.
