In America the average bridge is 42 years old and the average dam 52. The American Society of Civil Engineers rates around 14,000 of the country’s dams as “high hazard” and 151,238 of its bridges as “deficient”. This crumbling infrastructure is both dangerous and expensive: traffic jams on urban highways cost America over $100 billion in wasted time and fuel each year; congestion at airports costs $22 billion and another $150 billion is lost to power outages.
The B20, the business arm of the G20, a club of big economies, estimates that the global backlog of spending needed to bring infrastructure up to scratch will reach $15 trillion-20 trillion by 2030.
