Broughton Parish Council is delighted that the new bypass is due to open on Thursday (5 October). The new road will bring relief to the village after years of congested traffic.
The £32m bypass is expected to reduce the number of vehicles travelling through Broughton village by up to 90%, and improve journey times in and out of Preston.
Parish council chair Pat Hastings said:
"We have waited many years for this bypass, and now it is finally here we can celebrate the positive effect it will have on the quality of life for the people of Broughton.
"The bypass will also help motorists who have suffered long delays trying to travel through the village."
The official name for the new road in Broughton is James Towers Way, in honour of a local hero of World War One. Broughton-born Private James Towers was awarded the Victoria Cross (VC) for his actions almost 100 years ago. He was serving in the 2nd Battalion, The Cameronians (Scottish Rifles) in northern France.
The new name was chosen by Lancashire County Council, following a recommendation by Broughton Parish Council.
Construction work was carried out by Hochtief UK, on behalf of Lancashire County Council.
