National Highways has appointed an international group of construction companies to carry out controversial works to the A303 in the South West.
The £1.7bn upgrade of the road between Amesbury and Berwick Down includes a two-mile-long tunnel under Stonehenge.
The Government-owned organisation's preferred bidder for the scheme is a joint venture - known as MORE JV - that comprises Spain’s FCC Construcción, Italian business WeBuild and Austria-headquartered BeMo Tunnelling.
