Residents and businesses in Adlington are bracing themselves for road chaos as the latest rail electrification work began this week.
It is feared temporary double yellow lines for up to six months will cause severe problems.
Five bridges over the railway between Bolton and Chorley on the Manchester to Preston line are to be rebuilt as part of the electrification of the route.
A full closure of Rawlinson Lane, Adlington, is already in place until May 22, and Chorley Road, Heath Charnock, closed yesterday until June 19.
Paul Pennington, 45, and his wife Avis, 50, of Church Street, complained, but have now been told that initially the restrictions on Church Street will not be installed beyond the point currently covered by the zebra crossing zig zag.
However, he said others, including those on Railway Road, would be badly affected. He said the work would create the best part of “two miles of double yellow lines”.
Helen Brown, of florist Budz by Helen Jane, Church Street, feared for her business.
She said: “They are effectively cutting the village in half, with only one access road which will have traffic lights.
“They are going to put double yellow lines all the way down Railway Road.”
Ian Joslin, area director for Network Rail, said: “I apologise for the disruption but we have worked closely with the local authority to plan the diversions and will complete the work in the quickest and safest possible way.”
Lancashire County Council declined to comment.
