Rio's Expensive New Olympic Rings.

THE ECONOMIST/ With Map Of Proposed Sites/

Why did Rio win? “We wanted it more,” said Carlos Roberto Osório, of Brazil’s Olympic committee.
"That was the easy bit. Holding the games will require effort and expense on a scale that Rio, a problem-studded metropolis of 12m (half of whom live in the city itself), has never seen. Apart from new stadiums and other sports facilities of all kinds, the plans call for new bridges and roads, and a doubling in the number of hotel rooms. To revamp a chaotic transport system, engineers will blast through granite mountains to extend the metro from Ipanema to Barra da Tijuca, 13.5km (8.4 miles) away. Tens of thousands of athletes must be squired to scattered events through some of the worst traffic in the Americas."
