Each year in June, the people of the comunidad campesina of Huinchiri, along with villagers from three other nearby communities, rebuild a suspension bridge across the canyon of the upper Río Apurimac. The bridge is a keshwa chaca made of ropes hand woven of qqoya grass, a type of Andean bunchgrass. A steel girder bridge crosses the canyon a short distance upstream from the keshwa chaca, so it is not necessary that this rope bridge be rebuilt for any present-day transportation purposes. And yet the Quechua people continue to build the bridge annually, as apparently they have done since Inka times. It is their custom, and by maintaining the bridge they honor their ancestors and Pachamama.
Japan is the home of the small picturesque bridge of timber arches, frequently built without the use of a single metal nail or bolt. Christian Barman cites Japanese bridges as examples of ‘exquisitely perfected temporary construction’. Briges and temples were often rebuilt anually. the famous Kintai-kyo bridge at Iwakuni used to have its five arches rebuilt in succession, so that the whole bridge was renewed every twenty-five years. According to Japenese belief structures must never be allowwed to fall into decay as that would enfeeble the spirit of continuity on which the survival of mankind depends (H. Shirley 32).
Perrine's Bridge is the second oldest bridge in the State of New York, after the Hyde Hall Bridge in East Springfield. Once located in the hamlet called Perrines Bridge between 1850 and 1861. It is located in the modern day town of Esopus-Rosendale, New York just a few hundred feet to the east of Interstate 87 crossing of the Wallkill River in Ulster County, New York. Originally built to aid in the movement of trade between the towns of Rifton and Rosendale, the bridge is about two hours northwest of New York city between mile markers 81 and 82 on the New York State Thruway (I-87).
