Work is due to start in South Ribble this spring to cut congestion on a major route into Preston.
The £8m project is set to cut journey times on the A582 in South Ribble, with two phases of work from May to September and October to next March.
And Lancashire County Council’s cabinet member for highways and transport said he was pleased the work was now getting started.
The work is part of plans to increase capacity on routes outlined in the County Council’s highways and transport masterplan for the area. It is also one of four major highway schemes to receive funding under the Preston, South Ribble and Lancashire City Deal.
County Coun John Fillis said: “The City Deal and further improvements to infrastructure outlined in our transport masterplan are vital to trigger the creation of thousands of new jobs and thousands of new homes over the next decade and I’m very pleased we’re getting started.
“We’re keen to deliver the benefits as soon as possible and this work on the A582 will have an immediate impact to relieve current congestion.
“We’ve chosen to do this first as the work needed is within the bounds of the existing highway which means it’s more straightforward than other schemes where more extensive planning is needed. We realise this is a very busy route into Preston and our engineers have given careful thought as to how to carry out the work while keeping disruption to a minimum. In order to minimise disruption, works which may restrict traffic flow will only be undertaken outside peak commuting times.”
The first phase of the work will see the section of the A582 Golden Way north of Cop Lane widened to a dual carriageway, and increase the number of lanes at the junction with Chain House Lane. To allow the improvements to start in May, preparation will be carried out this month to remove trees and hedging to avoid disturbing nesting birds.
Further work is planned to take place on the A582 from October to March next year.
Traffic signals will be added to the roundabout at Stanifield Lane, and the section of Golden Way south of Cop Lane to the Broad Oak roundabout will be widened to dual carriageway.
