Wow, puentes que crecen en la selva. Wow indeed. Deep in the
rainforests of the Indian state of Meghalaya, bridges are not
built, they’re grown. For more than 500 years locals have guided
roots and vines from the native Ficus Elastica (rubber tree)
across rivers, using hollowed out trees to create root guidance
systems. When the roots and vines reach the opposite bank they
are allowed to take root. Some of the bridges are over 100 feet
long and can support the weight of 50 people. submission by
