Work to replace a gas main near Fosse Park begins today.
National Grid is replacing more than 550 metres of gas mains alongside the A5460, which links the M1 and M69 motorways to the Asda/Fosse Park roundabout.
The work will be carried out across the seven-lane road in sections, starting on the carriageway heading into Fosse Park from the motorway.
It is expected to take about about a fortnight to complete, with lane closures in place.
The project had been due to start during the school half-term in May, but was postponed after complaints from motorists and retailers at Fosse Park.
National Grid has said the work is essential to keep gas flowing safely and reliably.
Project manager Martin Brady told the Mercury that existing, ageing iron gas pipe needs to be renewed and will be replaced with a hard-wearing plastic pipe that has a lifespan of 80 years.
He apologised for any disruption it will cause.
As each section is finished, the road surface will be reinstated and reopened to traffic.
Work will take place between 9.30am and 3.30pm, outside of peak traffic hours, and traffic management staff will be on site at all times to manage lane closures and keep traffic flowing as much as possible.
Engineers from Triio, a partnership between Skanska and Morrison Utility Services, are carrying out the work on behalf of National Grid.
