Drivers are facing misery as work to replace the main water pipe under Burnley Road is causing long delays on the busy A646 route between Halifax and Todmorden.
Yorkshire Water began the project to upgrade the water pipe - which has burst six times in the last five years - in Luddenden Foot on Monday and the work has already attracted criticism from those who use the road regularly.
At peak times, drivers have reported queues stretching back over one mile in both directions as work is carried out from the junction with Danny Lane, to just before the Springfield Camping Shop, Luddenden Foot.
The project is expected to last for five weeks and with more work scheduled to start next year, motorists are set to face even more frustration.
Two-way traffic lights will be in place on Burnley Road for the duration of £170,000 project and will be manned during peak hours.
Ross Housley, Project Manager for Yorkshire Water, said: “We’d like to apologise to residents and road-users for any inconvenience caused.”
The work is another setback for motorists following prolonged gasworks earlier in the year and proposals for work beginning in the area next year.
Geoff Willerton, Calderdale Council’s Head of Planning and Highways, said: “This is only at the proposal stage, so full details and dates are yet to be confirmed, but we will be liaising with Northern Gas Networks to ensure that disruption is kept to a minimum.”
