Money to be spent on the A303.

A tunnel under Stonehenge is among the projects in the government’s £15bn Road Investment Strategy, the details of which were announced by the Department for Transport and the Treasury today.

Money for the new initiative, which covers investment lasting up to 2021, was first announced last year. It will triple investment in the roads by the end of the decade, the government said, with the announcement coming as a report from the RAC Foundation predicts there could be an additional seven million road users in England and Wales – taking the total to 43 million – within 20 years.

Included in the proposals is the long-rumoured 1.8-mile dual-carriageway tunnel under Stonehenge on the A303. The road links the M3 to Devon and is notorious for congestion. The project is part of £2bn to upgrade the south west road network, which also includes plans to dual the A358.
