Planning ahead for closure of the A39 near Street

A major engineering scheme to repair and rebuild the main road between Street and Glastonbury is being planned for later this year.

The A39 Causeway near Street is showing signs of significant structural failure and has seen 67 separate visits to fix potholes in the past two years.

Somerset County Council needs to reconstruct the carriageway, excavating to depths of more than one metre. Due to the width of the carriageway, the only way to do this safely is by fully closing the road.

Clearly this will be disruptive, so the County Council has started talks with the local community at the earliest opportunity to try to understand their concerns and minimise the impact.

The scheme is currently being planned for the October half term (22-30), when roads are quieter. Teams will work 24 hours a day for the duration of the closure, which is expected to last up to seven days.

Cllr David Fothergill, Somerset County Council’s Cabinet Member for Highways, said: “I think everyone will agree this road is in desperate need of improvements. We’ve carried out a lot of repairs at this location but really we need to close the road and do a proper rebuilding job.

“There’s no perfect time to do this. We’re aware it has the potential to be extremely disruptive, so we wanted to give everyone as much notice as possible. If you have a concern, please come and talk to us as soon as possible.”

To complicate the scheme further, there are various utilities, such as electrical cables and gas and water pipes, in the area of excavation. The County Council will be working closely with utility firms as the scheme is developed to explore joint working opportunities.

Details are still being finalised and further information will follow as the extent of the scheme becomes clearer. However, you can find out more about the work by clicking the links below
