More traffic misery is set to hit commuters using Broughton Roundabout as repairs are carried out on work only just completed.
Diversions and closures will be in place at the site over five nights in April while Lancashire County Council carries out resurfacing work.
The A6 at the Broughton Roundabout, including all access onto and off the M55 at Junction 1, will be closed completely from 8pm to 6am on the nights of Sunday, April 6, Monday, April 7 and Tuesday, April 8.
On Wednesday, April 9 and Thursday, April 10, while a full closure of the roundabout is not needed, various approaches will be closed with signed diversions in place.
On Friday, April 11, the roundabout will be fully open but nearby D’urton Lane will be closed from 8pm to 6am.
The work is needed because the material supplied for the new road surface during recent improvements to the roundabout was faulty and the surface is already beginning to fail.
Steve Simpson, north of England general manager for the suppliers Hanson Asphalt, said: “We accept that this surface has failed and will be co-operating fully with Lancashire County Council to carry out the remedial works with minimum disruption to road users.
“In the meantime, we are continuing to work with our supply chain and the council to investigate both the material quality and ingredients to try and establish exactly what went wrong.”
Work took place from June to December last year to make space for more traffic and reduce delays at what was one of Preston’s worst congestion hotspots.
The £2.6m scheme widened junctions, added traffic controls and feeder lanes and made it safer to use for pedestrians and cyclists.
It was designed to provide smoother transition for vehicles entering and leaving Preston and the first project under the Highways and Transport Masterplan for Central Lancashire to be completed.
Shaun Capper, assistant director for Lancashire County Council highways, apologised to commuters and local residents, but said disruption will be kept to a minimum.
He said: “It’s unfortunate that we’re having to do this work again, but it will be completed at no cost to the county council and we would prefer to do it sooner than later before the surface becomes worse and results in real inconvenience to road users.
“We’re sorry for the short term disruption, however people commuting at the usual peak times will not be affected as work will only be carried out overnight.”
