A final decision over a controversial Leyland development has been delayed while a traffic assessment is carried out.
Peel Holdings already has permission to build 60 homes at the current Roadferry site off Carr Lane.
But subsequent plans to change the access route to busy Northgate has caused uproar among residents, who say the plans will cause traffic chaos.
A final decision on the plans was expected to take place this month, but has been delayed with Lancashire County Council undertakes a highways assessment to determine whether Northgate can cope with the hike in traffic the plans would create.
Outline planning permission for 60 homes on the site was granted in March 2010 but the application approved access off Carr Lane, not Northgate.
It is now proposed that all traffic will go down Northgate and a cycle link and footpath could be built on Carr Lane.
Seven people have already objected to the proposals, including the Ainscough Group, who own land at nearby Farington Business Park and were refused access onto Northgate for their development for 471 houses and apartments, which was passed in 2009. Following the application by Peel Holdings, they also submitted a further application to use the road.
Angry residents have demanded the plans be refused.
In a letter to planners, Richard Redgrove, of Kennett Drive, said: “There have been several incidents of road rage and near collisions because of the volume of traffic and the problems with entering and exiting Northgate. To even suggest opening it up to further congestion is absurd and dangerous.”
Coun Caleb Tomlinson, who represents the Leyland Central ward at South Ribble Council, said: “If you try and get out of Northgate at 5pm now, it is impossible. With an extra 150 cars, it is an accident waiting to happen.”
Agents Lambert Smith Hampton, who are working on behalf of Peel Holdings, were unavailable for comment.
