Richard Hammond reveals how engineers made one of the longest bridges in the world earthquake-proof.
Building a structure almost 3 kilometres long in water 65 metres deep was almost the least of the engineering challenges of bridging the Gulf of Corinth in Greece.
The construction would cross one of the most active seismic fault lines in Europe. Defying disaster called for solutions inspired by fragrant Indian incense, the ring-pull in a soda can, a toboggan, a hammock, and some shiny steel chimneys.
