Simple suspension bridges, for use by pedestrians and livestock, are still constructed, based on the ancient Inca rope bridge but using wire rope and sometimes steel or aluminium grid decking, rather than wood. Living root bridges in Nongriat village, Meghalaya. In modern bridges, materials used instead of (fiber) rope include wire rope, chain ...
Written documentation of living root bridges was sparse until the 2010s, but in 2017, researchers geo-located a total of 75 living root bridges. [9] Living root bridges have also been created in the Indian state of Nagaland, [10] in Indonesia at Jembatan akar on the island of Sumatra, and in the Banten province of Java, by the Baduy people.

In an underspanned suspension bridge, also called under-deck cable-stayed bridge, [21] the main cables hang entirely below the bridge deck, but are still anchored into the ground in a similar way to the conventional type. Very few bridges of this nature have been built, as the deck is inherently less stable than when suspended below the cables.
A squirrel bridge is a construction (similar to a wildlife crossing) which enables small animals, especially squirrels and martens, to safely cross busy roadways. The bridges are a measure for wildlife management and natural habitat preservation, and serve the functions of both animal welfare and accident prevention.
Made of grass, the last remaining Inca rope bridge, reconstructed every June, is the Q'iswa Chaka (Quechua for "rope bridge"), spanning the Apurimac River near Huinchiri, in Canas Province, Quehue District, Peru. Even though there is a modern bridge nearby, the residents of the region keep the ancient tradition and skills alive by renewing the ...
Cables on the earliest suspension bridges were anchored in the ground; some modern suspension bridges anchor the cables to the ends of the bridge itself. Earliest suspension bridges had no towers or piers but the majority of larger modern suspension bridges have them. [1] All of the 14 longest bridges in the world are suspension bridges.
Queshuachaca [Note 1] (from Cuzco Quechua q’ichwa chaka 'straw-rope bridge', Quechua pronunciation: [q’es.wa cha.ka]) is the last remaining Inca rope bridge, consisting of grass ropes that span the Apurímac River near Huinchiri, in Quehue District, Canas Province, Peru.
