Drivers coming in and out of Burnley town centre will face delays over the next few months as a major £500,000 engineering project gets under way.
The work by Electricity North West is aimed at improving the electricity supply to around 17,500 residents and will affect a major gateway into the town.
Contractors will replace 1.6km of underground cable between Centenary Way and Athletic Street and temporary traffic lights will be installed in Centenary Way.
The project, which is due to be completed by June, will replace oil-filled cables which have been in place for around 50 years, with new environmentally-friendly and efficient cables.
Mr Chris Dunn, major projects programme manager for Electricity North West, said: “This project will help secure the supply of electricity to local residents and businesses for many years to come.
“It is vital that we replace and upgrade these cables, which have been in place for many years, to ensure customers receive the power they need.
“Unfortunately there is no way to install underground cables without some disruption, but I hope drivers and residents in the area understand the need for this essential project and we promise to keep any disruption to a minimum.”
Working closely with Lancashire County Council, Electricity North West will schedule temporary traffic lights to be installed on Centenary Way while the essential work is carried out.
Residents with queries about the work are advised to call Electricity North West on 0800 195 4141.
