Architect Mayur Kanaiya spoke highly of the Langkawi Sky Bridge, a 125 meter-long curve cable bridge atop Gunung Mat Cincang mountain in Malaysia.

Meghalaya Tree Roots Bridge

The village of Cherrapunji in the state of Meghalaya in northeast India — known as one of the wettest places in the world — builds bridges out of tree roots.

Some of the bridges are more than 30 meters long and can support the weight of 50 people.

The Rolling Bridge

In London, the 12 meter-long Rolling Bridge curls to one side to let boats through the Grand Union Canal at Paddington Basin. Every Friday at noon, the bridge opens.
