Lots of countries have big construction projects that become a byword for ineptitude. In America the “Big Dig", a highway project that snarled up the centre of Boston for years, came in five times over its initial budget. The stadium built for the Montreal Olympics in 1976 was unaffectionately known as the “Big Owe" after costs overran massively; the debts from the games were paid off only 30 years later. Even the Germans get megaprojects wrong. Ground was broken at Brandenburg Airport in Berlin in 2006, and the first flights took off in 2020, ten years later than scheduled.
