Weary motorists are facing further delays this week after more roadworks started on a busy route into Wigan town centre.
Drivers faced long queues when United Utilities carried out work to repair a burst water main on Whelley last month.
Less than two weeks after that work finished, they are now experiencing further delays as the water company installs a double hydrant further along the same road.
Multi-way traffic signals were put in place at the junction of Essex Street yesterday, which should be manned daily from 7am to 7pm.
Motorists using Whelley and surrounding roads have already met lengthy delays due to the work, with tailbacks to Wigan town centre and Aspull during the morning and evening rush hours.
The work is scheduled to be completed by Friday.
A spokesman for United Utilities said: “This is the latest phase in our multi-million programme to improve the water supply system in Wigan. We are cleaning miles of water pipes serving around thousands of customers, so they can continue to enjoy fresh, wholesome water from the tap.
"We have had to install temporary hydrants in the road to support the cleaning process underground; we know roadworks can be disruptive. We have put advance warning signage around and posted information along the stretch of road impacted.”
Mark Tilley, assistant director for infrastructure and regulatory services at the council, said: “The temporary lights are to allow United Utilities to install a double hydrant in the carriageway.
"We have urged them to closely monitor the timings of the lights to improve traffic flow and for additional signage.
"We are monitoring this closely to help alleviate congestion in the local area and will review the permit if traffic doesn’t improve.”
