WORK on a major project to upgrade the busy Dunball roundabout linking Bridgwater and Junction 23 of the M5 is set to start next month.

Construction on the scheme is scheduled to begin on November 11 and it aims to make it easier to walk and cycle at the roundabout, as well as improving traffic flow and capacity.

The project, being delivered by contractor Centregreat, will see the roundabout improved and signalised with the addition of a ‘throughabout’ lane which allows traffic to flow through the middle of it for greater capacity, with the aim of easing peak traffic flow.

This is alongside the construction of Agratas Gigafactory on the site of the Gravity Smart Campus in Puriton, which is set to create 4,000 jobs in Somerset.

Most of the improvements will be done with lane closures and temporary traffic signals in place but the scheme will require some short-term evening closures of the link road between the Dunball roundabout and J23 in early 2025.

People will still be able to enter and exit the M5 via J23 following diversion routes. Advanced notice will be issued, and diversion routes published as soon as possible.

The project’s total value is £10.7 million, wholly financed by ringfenced Government and partner funding, along with developer contributions.

As well as a contribution from Government, the Dunball scheme has been funded jointly by developer contributions, the Heart of the South West Local Enterprise Partnership (LEP), National Highways, and Bridgwater Town Deal.

Councillor Richard Wilkins, Somerset Council’s Lead Member for Transport and Digital, said: “This is a vital project at a very busy interchange where there can sometimes be significant delays for road users during peak times, and it is also very difficult to access for pedestrians and cyclists.

“Improving traffic flow at this roundabout is vital for the county’s continued economic growth, with massive investment set to come to Bridgwater in the coming years.

“Dunball comes at a busy time for Bridgwater with major ongoing work on two important schemes in the area – the Celebration Mile and Agratas power supply works.

“These projects represent a big investment in the area, but also bring significant pressure on the road network in and around Bridgwater.

“Ideally, the work would be staggered, but all the projects are highly time-sensitive and in the case of Celebration Mile and Dunball, funding must be spent within a certain timescale.

“This is a challenging time and we understand there will be concerns locally. We will be working hard to ensure works can be coordinated in a way that reduces disruption as much as possible.

“Ultimately this is about an incredibly positive future for Bridgwater and Somerset.”

A local engagement event is planned nearer the start date for the public and businesses to come and find out more about the project. Details will be shared soon.
