Despite strong opposition from archaeologists and groups related to the protection of historical heritage and landscape, the British government has approved the construction of the underground highway near Stonehenge, necessary to reduce traffic congestion on the A303 between the southeast and southwest of the country.

In 2021, UNESCO was concerned about the project’s development due to its impact on the value of Stonehenge, Avebury, and Associated Sites. The Stonehenge complex has been declared a UNESCO World Heritage Site and any project adjacent to or in its vicinity is subject to careful evaluation by UNESCO to ensure the protection of its historical and cultural significance. UNESCO has expressed particular concern about the possible negative impacts on the landscape, archaeological features, and the overall integrity of the site, condemning the current form of the project and even threatening to remove Stonehenge from its list, but it didn’t manage to stop the approbation process.

It is estimated that the cost of the project will amount to around $2.2 billion, and that construction works will begin in 2024.
