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).
CAMBRIDGE, Mass. — Conquistadors from Spain came, they saw and they were astonished. They had never seen anything in Europe like the bridges of Peru. Chroniclers wrote that the Spanish soldiers stood in awe and fear before the spans of braided fiber cables suspended across deep gorges in the Andes, narrow walkways sagging and swaying and looking so frail.Yet the suspension bridges were familiar and vital links in the vast empire of the Inca, as they had been to Andean cultures for hundreds of years before the arrival of the Spanish in 1532. The people had not developed the stone arch or wheeled vehicles, but they were accomplished in the use of natural fibers for textiles, boats, sling weapons — even keeping inventories by a prewriting system of knots.
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).
Luoyang Bridge, China’s earliest stone beam bridge built in the seaport, spans the Luoyang River from south to north in the southern suburb of Quanzhou... Luoyang Bridge was built from 1053 and was completed in 1059... Built from light grey granite, the bridge resembles a silver dragon lying above the green water. The bridge features ship-like piers and a unique method of oyster consolidation. The ship-like piers could easily cut the rapid current in the river. Thousands of oysters were bred around the footstones and piers so that their secretions would act as kind of cement. This was the world’s first example of the use of biology in bridge building and shows the great wisdom of the ancient Chinese people.
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).
