The Pul-i-Khaju at Isfahan.
The use of a bridge to serve also as a dam is not uncommon in Persia, where the scarcity of water necessitates impounding it in reservoirs for irrigation of the land (H. Shirley 26).
travellers made their parched and dusty way through thte guarded gateways of the bridge, seeking rest and refreshment in teh cool shaded pavilions and caravanserai to be found upon it. For to the Persians, bridges were much more than simply a means of crossing a river. By the seventeenth century some of them, such as the Allahverdi-Khan and Pul-i-Khaju, were designed as delightful retreats form teh heat and dust of the desert (H. Shirley 27).
The superstructure is built on a dam which impounds the river to a height fo six feet. From this reservoir irrigation channels lead the water to the fertile lands on either side. The dam is of stone, pierced by narrow openings, the flow through which is regulated by sluices. The bridge is 85 feet wide and consists of some twenty-four brick arches with an overall length of 462 feet... Together with Old London bridge in its prime and the Ponte Vecchio in Florence, it constitutes one fo the great bridges that were closely linked by the buildings on them to the multitudinous life of their times (H. Shirley 28).
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.
