Motorists are set to face another six months of roadworks as a £7m interchange project begins.
The scheme at Broughton Interchange - where junction 32 of the M6 links with the Blackpool-bound M55 - will get underway in May.
The project will involve widening the northbound M6 carriageway, and highways bosses have urged drivers to be patient during the summer-time disruption.
County Coun John Fillis, cabinet member for highways and transport, said: “Like all developments - and this one is quite a major one because it affects a lot of traffic - it will have a disruptive short-term affect.
“But as we’ve seen from drivers, we are making improvements and we get a positive response as long as people keep moving.”
He said: “In the short term it will be frustrating, but I think drivers appreciate that things are going to be much better and in the long term it will provide a great improvement.”
The M6 improvements, part of a wider government intitiative, are due to start on May 12 and are hoped to be completed in November. Short lengths of the hard shoulder will be used to add an extra lane on the approach to and through the interchange.
Alan Shepherd, the Highways Agency’s north west director, said: “Serving commuters and holiday makers travelling to Blackpool and the Lakes, this interchange is important to the economy of the whole region and the improvements will reduce congestion and improve safety.”
Traffic management for the project will include some hard shoulder and lane closures, as well as overnight slip road and carriageway closures.
