Footbridge made from cardboard tubes

Cory Doctorow: A new bridge made of cardboard tubes has been erected over the Gardon river in southern France by a Japanese architect named Shigeru Ban.

Built half a mile from the Pont du Gard -- a section of ancient Roman bridge classed as a UN World Heritage site -- Shigeru's cardboard-tube structure is strong enough to carry 20 people at a time.

Reaching over the water to a sandy islet mid-river, it opens to the public for six weeks starting on Monday, before it is dismantled for the rainy season...

Weighing 7.5 tonnes, the bridge is made from 281 cardboard tubes, each 11.5 centimetres (four inches) across and 11.9 millimetres thick. The steps are recycled paper and plastic and the foundations wooden boxes packed with sand.
