A section of St Cenydd Road in Caerphilly is set to close to allow gas pipe upgrades to take place.
The project, which will see the stretch of road between Martin’s Farm and Trecenydd Industrial Estate close in both directions, will begin on Monday, July 29.
The closure is expected to last for weeks with diversions will be in place.
The works will be carried out by Wales and West Utilities and will involve upgrading nearly one and a half miles of pipes. It is expected to cost around £340,000.
Wales and West Utilities said it is carrying out the work over the school holidays to ‘minimise’ the impact on traffic.
The company said the work was “essential to keep the gas flowing to heat homes and power businesses in the area so that people are safe and warm for generations to come”.
Wales and West Utilities Programme Controller, Adam Smith, is managing the work and said: “While most of the gas network is underground and out of sight, it plays a central role in the daily lives of people across Caerphilly. Whether it’s heating your home, making the family dinner or having a hot bath, we understand how important it is for your gas supply to be safe and reliable and there when you need it.
“We know that working in areas like this is not ideal, but it really is essential. We’ll have a team of gas engineers on site throughout the project to make sure our work is completed as safely and as quickly as possible while keeping disruption to a minimum.
“This work will not only keep the gas flowing safely and reliably today, it will also help make sure the gas network is fit for the future and can play its part in delivering reliable and affordable green energy.”
The diversion route in place will see traffic directed through Nantgarw Road, onto the Penrhos roundabout and then back towards the St Cenydd roundabout via the A469.
Meanwhile, works to strengthen Trecenydd footbridge will not be taking place this summer.
Cllr Sean Morgan, Caerphilly County Borough Council’s cabinet member for infrastructure, said: “The works have been deferred to enable officers to consider a method of working which minimises disruption to the public. Works may now begin in 2020 and during the summer holidays when use by pedestrians will be at its lowest. I would like to assure residents that the council will inform them in advance of any works beginning.”
Proposed works on the footbridge include structural steel repairs, repainting and improvements to the anti-skid surfacing.
