Natural Architecture

Strong bridges don't necessarily have to be guilty from steel and cement.  For that matter, they don't even have to be built.  In northeastern India, amazingly strong bridges are grown using the roots of rubber trees.  the rubber tree roots are guided to the other side of the river using hollowed our betel-tree trunks.  Once there, the roots start growing in the soil.  After about 10 or 15 years, a functional bridge is formed.  Another type of natural bridge is foudn in Japan's Ilya Valley.  There, bridges are made from growing and weaving long lengths of the exceptionally strong Visteria vine.  Some of these vine bridges are thought to have gotten their start in the 12th century.

Interesting huh?

I've seen some bridges in photographs like these that you mention. I had no idea how this was accomplished.
