Building a physical bridge between the UK and France is, apparently, ridiculous. I know that because, ever since Boris Johnson raised the prospect at the Anglo-French summit, my Twitter feed has been full of comments from various bien pensants ridiculing the idea.
‘If you like the Boris bridge idea, wait ‘til you hear about Liam’s plans for a zip wire from Washington DC to Washington, Tyne & Wear,’ quipped one commentator, referring not to me (on this occasion) but to Trade Secretary Liam Fox. ‘David Davis wants a pedalo from Boston, Massachusetts to Boston, Lincolnshire!’ parlayed another keyboard wag.
As it happens, the construction of a bridge across the English Channel bridge is entirely feasible. Detailed plans, drawn up by an engineering consortium, with finance in place, were considered by the Department of Transport as long ago as 1981.
