    • Essential, urgent work to make sure there is a safe network in place
    • Details of road management, starting Monday 6th November, along the A12
    • Road will remain open throughout the day, but reduced to two-way traffic

    A project to replace gas mains under the A12 near Woodbridge, Suffolk, is set to get underway on Monday 13th November.

    Cadent, which manages the local gas distribution network, is carrying out these essential works to make sure there is a safe and reliable network in the local area. The underground gas network carries gas into buildings, where it provides warmth in winter, hot water, and fuel for cooking.

    Recent repair works in the area have revealed that the ageing gas main is showing signs of corrosion and needs to be replaced.

    This means that Cadent’s teams will need to dig a deep excavation along the A12, Grove Road, measuring almost 800 metres in length to access the main and associated pipework.

    As a result, there will be the following temporary road management put in place:

    • Narrowing of the A12 between Monday 13th November and Friday 22nd December allowing two-way traffic;
    • Two-night closure of A12 approaching the roundabout close to Dobbies Garden Centre on 11th and 12th December;
    • Closure of righthand lane of the southbound A12 carriage way between 11th and 22nd December
    • Closure of pathway on roundabout close to Dobbies Garden Centre between 11th and 22nd December

    When road closures are in place, diversions will be set up to ensure that traffic continues to flow.

    “We’re carrying out this work to keep gas safely flowing into all the local buildings in the area,” explained Paul Angel, Cadent’s Lead Delivery Engineer (East of England).

    “Having inspected the pipework, it is clear that we have carried out extensive work in the area aleady, but repair is not an option in this instance and a replacement needs to take place.

    “With the planned Sizewell C Nuclear Plant building project getting underway, we felt that it was important to get this replacement work carried out sooner rather than later to ensure that any further disruption was kept to an absolute minimum.

    “We would like to thank customers in advance for their patience and we apologise for any inconvenience experienced as we complete this important work.”

    Despite the large project taking place, we plan for the gas supply to remain uninterrupted to homes and businesses in the area.


    Cadent is the UK’s largest gas distribution network with a 200-year legacy. We are in a unique position to build on strong foundations whilst encouraging the curiosity to think differently and the courage to embrace change. Day to day we continue to operate, maintain and innovate the UK’s largest gas network, transporting gas safely and protecting people in an emergency. Our skilled engineers and specialists remain committed to the communities we serve, working day and night to ensure gas reaches 11 million homes from Cumbria to North London and the Welsh Borders to East Anglia, to keep your energy flowing.

    Future of Gas:

    Here at Cadent we support the Government’s plans to reach Net Zero by 2050. That means we’re backing the introduction of hydrogen as a low carbon alternative to natural gas for the future. We know people love the controllability of gas and, with our network already in place, it makes sense to switch to the lower carbon alternative offered by hydrogen, which we believe can keep homes and businesses warm for generations to come.
