First it was paper cranes, now it’s bridges. Architect Shigeru Ban is moving us along the twenty-first century by using very old technology: paper! Ban has created an cardboard bridge in France.

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.

It’s environmentally friendly, can be rebuilt and totally cool.
