National Highways has awarded contracts worth around £1.3bn for the delivery of controversial works to the A303 in the South West.
The government-owned organisation is looking to perform a £1.7bn upgrade of the road between Amesbury and Berwick Down, which could include a two-mile-long tunnel under Stonehenge.
The planning application for the transformational scheme is still awaiting redetermination from transport secretary Anne-Marie Trevelyan, after a High Court quashed predecessor Grant Shapps’ order to proceed with the plans in 2021. A legal challenge had been brought by campaigners concerned about the project's potential impact on the world heritage site.
