Drivers have been warned to expect disruption when work gets underway to revamp a roundabout as part of the dualling of the A11.

There will be three weekend closures on sections of the Fiveways roundabout at Barton Mills in Suffolk next month, with drivers facing a lengthy diversion via Bury St Edmunds.

The Highways Agency says the closures are needed so they safely carry out a complete reconstruction of the roundabout as part of the long-awaited dualling work to the road.

The first closures will take place on the northbound section of the A11 on its approach to the Fiveways roundabout, as well as on the A1101 north (Bury Road) in both directions (green area on the graphic).

That work will start at 10pm on Friday, October 4. The A11 northbound will re-open at 6am on Monday, October 7. There will be no access to, from or within the green area.

The second closure will take place from 10pm on Friday, October 11 to 6am on Monday, October 14. It will affect the northbound A11 from the Fiveways roundabout and the A1065 (Brandon Road) in both directions (blue area on the graphic). There will be no access to, from or within the blue area.

The third closure will be on the southbound A11 to and from the Fiveways Roundabout, and the A1101 south (Mildenhall Road) in both directions (yellow area of the graphic). It will take place from 8pm on Friday, October 18 to 5am on Monday, October 21. There will be no access to, from or within the yellow area.

Highways Agency project manager, Geoff Chatfield, said: 'The redesign of the Fiveways roundabout, which includes adding more capacity for road users, is an essential part of the project and will ensure that the roundabout continues to operate well after the dual carriageway opens.

'We have to close sections of the roundabout to give the road workers space to operate in. By doing it over three weekends we avoid the need to close the roundabout entirely, and means we can get the work completed as quickly and as safely as possible.

'We are committed to keeping disruption to road users to a minimum, so we have carefully planned the work to take place at weekends only, when traffic flows are lower, and outside of the busy school holiday periods.'

Highways bosses say there will be clearly signed diversions, for local traffic and drivers travelling over a longer distance.
