In north east India, bridges aren’t built – they’re grown! The rainforests of Cherrapunji are credited with being one of the wettest places on Earth, and timber bridges would quickly rot. Locals have an innovative solution – grow bridges out of living trees. Like many in the banyan family, the rubber fig has secondary roots that grow above the soil surface. By guiding these roots across chasms, villagers can slowly grow a strong, permanent bridge. Amazing pictures below the fold!

    That is amazing holy crud imgine the possibilities they should totally use that in like an Indiana Jones movie. That is simply amazing imgine if we were to use that more often for other types of engineering projects than we wouldn’t have to worry so much about global warming or structural integrity.

    Yeah that’s right! We wouldn’t have to worry about structural integrity at all! Doesn’t matter what weight you put on the bridge, nature will just like, kind of do it, yeah? Cool.

    And those bridges like, they sort of solve global warming as well. Wow.

    Simply imgine it.

    The only obstacle now is to undo the previous generation of environMENTAL rules that banned the Banyan tree. Too much growth, ban fast growing plants like the Banyan. Not enough green, ban industrial engineering.

    Very interesting!!! Thank you for sharing this – a bridge that will always take care of itself.

    I would imgining it too, if I knew what that means. These bridges are quite useless..Don’t see how they could support the weight of my Hummer.

    These bridges aren’t meant to accommodate Hummers, tard.

    Of course they’re not meant to accommodate Hummers; that was the joke, tard.

    You cant have a hummer made of tree roots, tard

    I would love to see this adapted for providing shade over roads or parking lots. Too much blacktop just baking in direct Florida summer heat.

    There’s a stretch of road near my house with big oak trees on either side. No matter the time of day, it’s aways in the shade. It’s beautiful, almost the iconic image of a two-lane rural road. But trees can’t support cantilevered limbs like that for anything more than two lanes. Fig trees supported on both sides seem like the only way to go.

    Nice idea, but these are roots not branches – they have no leaves, so not very good at creating shade!

    Found this through Stumble. Really cool idea. Only problem is that we in the West don’t have the patience for the years it would take to make a root bridge.

    Just imagine.. 5-10 years to build a bridge that you take 1-2 months to build with steel and concrete..

    Just saying that the concept is good for india.. but here? not at all..

    Looks good for now, but what happens when plants turn against us? The Fig isn’t part of the Venus Fly Trap family, is it? I’d hate to be eaten by a bridge.

    Well Indian govt. never leaves any steel or concrete for its people so they have to use these methods

    The bridges are in the rain forest. Are these bridges for monkeys?

    As a monkey I have no need or reason to use bridges, I merely swing from branch to branch.
