“Boris Johnson’s proposed bridge or tunnel to Northern Ireland could cost over £300bn and should not be built, a government review has found. The prime minister had commissioned a study into the fixed link across the Irish Sea after arguing it would improve connections between different parts of the UK. Network Rail chairman Peter Hendy’s review found that that a bridge would cost an estimated £335 billion, while a tunnel would be around £209 billion. Sir Peter said the high price tag of either project ‘would be impossible to justify’ as ‘the benefits could not possibly outweigh the costs’. Either a bridge or tunnel would be the longest of their kind ever built” – The Independent.
