Aecom wins role on £1.4bn A303 Stonehenge scheme


US-based engineering firm Aecom has been selected by Highways England to offer technical support in the detailed design and planning application process for the £1.4bn A303 Stonehenge scheme in the UK.

Aecom, in collaboration with Mouchel and Mace, will serve as Highways England's technical partner on the Amesbury to Berwick Down project. The A303 stretch from Amesbury to Berwick Down will be upgraded to a dual carriageway. Work will also include plans for a 1.8-mile tunnel near Stonehenge.

The team will be responsible for developing the project’s preliminary design, manage and lead on the development consent order application, as well as provide technical assurance of the detailed design and construction.

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 have enjoyed an excellent and productive working partnership with the Arup Atkins Joint Venture during the route options identification phase, and we are now looking forward to forging another successful partnership with Aecom.

“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.”

The eight-year contract is worth between £40M and £50M. Construction work on the project is expected to commence in 2020, subject to the result of the development consent order.
