The route is one of the busiest in South Ribble and it is set for a long-awaited upgrade between Lostock Hall and Penwortham. But what form should it take?
That was one of the questions facing some of the candidates standing to be South Ribble's next MP when they were quizzed during a hustings event in the constituency.
The Lancashire Post, Lancashire Lead, Blog Preston and the Local Democracy Reporting Service invited all five candidates contesting the seat at next week's general election to a debate in which they fielded questions from voters.
Four of those on the ballot took part in the event. In order of appearance from left to right on the stage, they are:
KATHERINE FLETCHER - Conservative
PAUL FOSTER - Labour
ANDY HUNTER - Reform UK
ANGE TURNER - Liberal Democrats
The one other candidate for the South Ribble constituency, who was unable to attend, is:
STEPHANI MOK - Green Party
