Plans for major engineering scheme taking shape

Innovative techniques will be used during a major engineering scheme to repair the main road between Street and Glastonbury.

The A39 Causeway near Street is showing signs of structural failure and Somerset County Council announced earlier this year that a road closure would be required for permanent repairs to be carried out.

Following extensive investigations and planning, details have now been confirmed.

An innovative resin injection system will be used to improve the strength of the road while keeping excavations to a minimum. This process will keep costs down and is better for the environment by reducing the need to transport and dispose of materials.

As the road will be need to be closed, the County Council has worked closely with all utility firms to check if any underground pipes or cables also require maintenance. The only affected equipment is a water main and Bristol Water has confirmed that this is in good condition and there are no plans for maintenance.

Cllr David Fothergill, Somerset County Council’s Cabinet Member for Highways, said: “This is a very challenging scheme and we’ve already done a lot of work to plan it as carefully as possible alongside partners and the local community.

“Now the details have been confirmed, I would urge everyone to get the dates in their diaries and start thinking about how they will get around that week. We’ll be working 24/7 to complete this essential work as quickly as possible, but fully appreciate there will be an impact on the travelling public.”

Work has been deliberately timed to take place when roads are quietest, during the autumn half term from Saturday 22 October to Sunday 30 October.
