Engineering challenges: Road closure extended due to complications

in your area

▪       Closure in part of Northampton’s Gold Street will take longer than initially anticipated due to major engineering challenges

▪       Engineers are having to cut through reinforced concrete and negotiate a multitude of other utilities  and underground services

▪       The project will help keep safe and reliable gas supplies flowing for cooking and heating


Engineers are using both force and finesse to carry out essential gas mains replacement work involving big engineering challenges in Northampton.


The closure of a 20m stretch of a bus, taxi, delivery and cycle route in Gold Street running from the junction with Horseshoe Street towards the city which was originally due to be lifted on Sunday 19 February but has now been extended until at least Sunday 26 February.


To carry out their work engineers are working to remove street surfaces made up of reinforced concrete slabs which sit above another layer of reinforced concrete. Beneath this tough exterior lie a labyrinth of cables and pipes belonging to other utilities.


National Grid Authorising Engineer Mark Allsop said: “With any project our pre-work surveys and the maps we are provided with from other utilities will only tell us so much - the complete picture only comes when we start work.


“Our engineers have found some major challenges with this work including having to break through tough reinforced concrete and then carefully configure a route for the new gas pipes amid a complex network of other cables and pipes.”


He added: “We’re sorry for any inconvenience this may cause people and we are doing all we can to complete the works as soon as possible. The end result will be positive and help ensure local residents and businesses keep on enjoying safe and reliable gas supplies in the future.”


The project also involves phased lane closures in Horseshoe Street, - access to homes and businesses continues to be maintained at all times.  All businesses will be open as usual. Access for motorists will be maintained via a signed diversion route. There will also be access to all main car parks.


Gas engineers may need access to businesses on Horseshoe Street to replace service pipes (the pipes that take gas from the main in the road to individual properties). This work will involve temporarily switching off the gas supply to the properties involved. Those affected will be notified beforehand.


All National Grid engineers carry official identity cards, which people should ask to see before allowing them on their property. Work started at the beginning of January 2017 and is currently expected to be completed sometime in April 2017.


To verify an engineer’s identity or for any enquiries about this work people should contact National Grid’s customer services team on 0800 096 5678.

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.
