Of all the bridges  that existed back then, the only one that remains today is the Q’eswachaka  or Queshuachaca (literally, “rope bridge” in the Quechua  language), which spans a narrow pass over the Apurímac River  in the province of Canas, located in the southern region of Cusco .

Last Inca bridge, Queshuachaca.
The Q'eswachaka is made out of ichu , a grass endemic to the Andean highlands. For more than 500 years, the local people have kept this tradition  of ancient technology alive. Every year in June, the rural communities of Huinchiri, Chaupibanda, Choccayhua and Ccollana Quehue come together  in a ritual ceremony to rebuild the bridge with the same raw materials and techniques used in the time of the Incas.
In 2013, the knowledge, skills and rituals related to the annual renewal of the Q’eswachaka bridge were inscribed  on UNESCO's Representative List of the Intangible Cultural Heritage of Humanity. According to that description:
[Las comunidades] consideran que este trabajo en común no es solamente un medio para mantener en buen estado una vía de comunicación, sino que es también una forma de estrechar los lazos sociales que existen entre ellas. El puente se considera un símbolo sagrado del vínculo que une a las comunidades con la naturaleza y con su historia y tradiciones […].
[The communities] see it as a means of strengthening their social links and not simply as a transport route. The bridge is considered a sacred expression of the communities’ bond with nature, tradition and history […]
The renewal of a bridge and the revitalization of a tradition
The first day begins with an oblation to the protector Apu . The main material for the bridge is collected and twisted into narrow strands. In the afternoon, the communities bring the material together, twisting the narrow strands into thick ropes — four for the floor of the bridge, and two for the railings.
The main ropes are then extended across the river. On the second day, they're secured to each side, and the old ropes are allowed to fall.
On the third day, the chakaruhac (Inca engineer) braids the bridge together to give the bridge a surface to walk on and to stabilize the railings by connecting them to the base.
Finally on the last day, the bridge is reopened with typical music and dances from the area.

Getting across Queshuachaca, last Inca bride of Peru.
A user posted on Twitter a video by AJ+ that shows how the bridge is braided every year:

For centuries, the hanging bridge Q'eswachaka is braided once more. Inca beauty that we can learn from to collectively achieve.
On Instagram, we can also find pictures of users who crossed the bridge:
