Stonehenge tunnel case ‘uncertain’
The economic case for building a road tunnel near Stonehenge relies on “uncertain” benefits, the public spending watchdog has warned.
A report by the National Audit Office (NAO) raised doubts over the estimated £1.15 benefit for every £1 spent.
The Department for Transport’s (DFT) controversial proposed upgrade of the A 303– which includes a two-mile long tunnel beneath the Stonehenge World Heritage Site – is forecast to cost between £1.5 billion and £2.4bn, the NAO said.
The road, which currently passes the stones, often suffers from severe congestion.
