Britain may be leaving the European Union, but the country's foreign minister Boris Johnson Wants to keep building bridges. Johnson has suggested building a 22-mile road crossing between the U.K and Europe following his country's departure from the European Union, or "Brexit." According to British newspaper The Daily Telegraph, Johnson said the bridge would boost tourism industry after the country leaves the European Union. Visitors to the U.K. must current a ferry service or the Channel Tunnel to reach the country. Speaking on Thursday, the leading Brexiteer said he thought it "ridiculous" that the two countries were only linked by a single railway. However, neither the British nor the French government have endorsed Johnson's suggestion. Downing Street has stated that it has "no plans” in place for the proposed bridge, while an aide for French President Emmanuel Macron clearly stated his opinion when he remarked: "Only 55 per cent of Channel Tunnel capacity is used on average — so before building a bridge, let's use the tunnel." Johnson has already supported ambitious infrastructure projects in the past that have not been realised As mayor of London, he opened the £60m Emirates Air Line cable car- which has failed to attract commuter traffic. Johnson wanted an airport built in the Thames estuary, but the idea was dismissed as impractical and costly in comparison to expanding Heathrow. He also backed the construction of a garden bridge across the Thames in west London which was ditched by his successor as mayor, for not offering value for money.
