We must cross the Firth of Forth for the people of Fife. But how can that be the price? (Yes, I saw the articles saying "At least 1bn pounds") But you could take over a third of Iraq for that price. And Google puts the most expensive bridge in the world (Akashi Kaikyo Bridge ) at a measly $4.3 billion US dollars and US billions. The chunnel comes in at a mere 21 billion US dollars and US billions. Unless my googling is sub-par.
