Dear all
I am writing to let you know about works planned on the A360 in the autumn for the A303 Stonehenge project. As members of the Community Forum, we’re keen to notify you early of these plans so that you can share with your contacts and communities.
Highways England is aiming to be on site later in the summer, and one of the first pieces of work that needs to happen is to connect an electricity supply for construction, and for the tunnel once built.
Scottish and Southern Electricity Networks (SSEN), working on behalf of Highways England, will be installing two high voltage electricity cables and a fibre optic cable along the A360 to connect the Salisbury grid substation to a new temporary substation at the construction compound next to Longbarrow roundabout.
To allow the work to be done safely and as quickly as possible, a section of the A360 - to the south of the A303 between Longbarrow roundabout and The Avenue roundabout - will be temporarily closed for approximately three months between early September and December.

Access will remain open during the works including for deliveries and access for emergency services. Directly affected residents and businesses will shortly be contacted by SSEN and will be regularly kept up to date on the latest access routes throughout the works.
Traffic will be diverted via the A345, and part of the A303 and A36. Signs will inform people about the closure from as far away as Devizes, Shaftesbury and the routes around to Salisbury to encourage drivers to find alternate routes at the earliest opportunity. Early notification signs are anticipated to be put out in July, with diversion signage just prior to the closure.
We’re working closely with Wiltshire Council, who are introducing weight limits for several minor roads – including through the Woodfords – to deter HGVs from using unsuitable local roads. While the work is being undertaken, we will monitor traffic levels on the diversion route and local roads in conjunction with Wiltshire Council and will introduce additional measures if required.
I’ve attached a map showing the closure, diversion route and weight limits.
We appreciate that this will cause some disruption, and thank people for their patience in advance. Starting with a briefing to Wiltshire councillors this morning, we are communicating widely at an early stage – some three months before the closure – to give plenty of notice to local residents and for people to plan journeys. We appreciate that this wide, early communication might mean that some of you may have received this information through other channels, such as from parish or town councils you may be involved with.
As you might also already know, we’re also running a community event at the end of the month to provide an update about the project generally including the works on the A360. I have included details below.

We are running an online Q&A session on Tuesday 29 June at 7pm. Please sign up – and submit questions, by scanning this QR code.For any queries about these works, please do visit our website, where information will be available shortly, or contact

Many thanks
