AECOM has secured an eight-year contract with Highways England to be its technical partner for the £1.4bn A303 Amesbury to Berwick Down improvements scheme, which includes a proposed tunnel alongside Stonehenge.
The infrastructure services firm will work with supply chain partners Mace and Mouchel to deliver a range of multidisciplinary services to support all phases of the project to upgrade the 8-mile stretch of road from single to dual carriageway.
The existing A303 at Stonehenge
As technical partner, AECOM will provide highways and tunnelling design services, as well as environmental, heritage, noise, traffic modelling and procurement consultancy services.
The road passes just 165 metres from the Stonehenge World Heritage site (WHS) and the project includes a proposed new tunnel alongside the site that aims to improve the setting of Stonehenge and other important monuments within the WHS.
Highways England project director for the A303 Stonehenge scheme Derek Parody said: ‘This award is another step in our commitment to deliver the A303 Stonehenge improvement scheme.
‘We are still busy developing the design of the scheme, following a successful public consultation, and although we are yet to receive permission to start construction, this appointment will help us to design the best scheme possible to improve this road and enhance the World Heritage Site, and to prepare for works getting under way on time and to budget.’
Dave Beddell, highways director – Europe, AECOM, said: ‘AECOM brings a breadth of expertise to this nationally significant project, working in collaboration with Highways England and our partners to support the scheme from start to finish.’
The project also includes a bypass for the village of Winterbourne Stoke, as well as improvements to existing junctions between the A303 and the intersecting A345 and A360.
The scheme is part of a wider strategy to create a new South West Expressway, which includes a package of improvements to the A303 - the most direct route between London and the South West.
