Johnson’s plan for Irish Sea bridge or tunnel rejected by official study

Review finds both would be vastly expensive, fraught with complexities and take at least 30 years to open

Boris Johnson's proposal for a bridge or tunnel linking Scotland to Northern Ireland has been rejected by a feasibility study as vastly expensive and fraught with potential difficulties.

Released alongside a wider so-called union connectivity review, which called for investment in road, rail and domestic aviation to better connect the four UK nations, the fixed link report found either a bridge or tunnel would be at the very edge of what could be achieved with current technology.
