NATIONAL Grid bosses have pledged to work seven-days-a-week if necessary to ensure a vital gas mains upgrade in Bury St Edmunds is completed as quickly and efficiently as possible.

A three-week improvement scheme to replace 25-metres of ageing iron mains with plastic pipes in Rougham Road is due to begin on Tuesday, April 2.

To ready the project, engineers will also be at the site from 7pm on Monday March 25, until 6am the next day, to carry out preliminary excavation work.

Three-way traffic lights will be manually operated on the A134 outside Bury St Edmunds Garden Centre.

National Grid project engineer Kevin Pettitt said: “We will be working extended hours to complete the work quickly, efficiently and with minimal disruption to residents, businesses and drivers.”

Once the project launches, on April 2, a two-way traffic lights system will be manually operated between 7.30am and 7.30pm on the A134 outside Bury St Edmunds Garden Centre to allow engineers to safely connect new gas mains to the existing system.
