10 Most beautiful bridges around the world with the Khaju Bridge from Iran
Today, the Brooklyn Bridge is one of the main crossings of the East River and one of the most heavily trafficked bridges in the world. But in the late 19th century, it took Roebling more than 14 years to convince the city to build the bridge.
After he got approval, Roebling was surveying a site when his foot was crushed by a ferry. Three weeks before the scheduled groundbreaking, he died of tetanus. His son, an engineer named Washington Roebling took over the project.
3-Designed by engineer David B. Steinman, the Mackinac Island Bridge joins Michigan with, well, Michigan, specifically the state's Upper and Lower Peninsulas.
4-Commissioned by Shah Abbas II in the 17th century, the Khaju Bridge across the Zayandeh River in Isfahan, Iran connects the Zoroastrian Quarter with the rest of the city. And it also functions as a dam! Recent renovations to the structure have created drama among Iranian architects.
5-Here it is, the tallest bridge in the world, standing 1,125 feet tall and crossing a valley in southern France. French engineer Michel Virlogeux and British architect Norman Foster designed this soaring example of Franco-Anglo cooperation, dedicating the structure in 2004.
6-Designed by New York architect Vito Acconci, the Aiola Island Bridge in Graz, Austria bridges the banks of the Mur River. The glassy structure, which opened in 2003, also houses a bar, a sunbathing area and a coffee house.
7-Puente del Alamillio, Spain.This striking bridge was built in 1992 to span the Canal de Alfonso XIII and La Cartuja, an island on the other side of the canal. Its structure of the single cantilevered pylon counterbalances the rest of the span. It was designed to show the soaring hopes of Seville for Expo 1992. The simple, elegant design results in one of the most beautiful bridges in the world.

9- -Pont du Gard.Pont du Gard, an aqueduct spanning the Gard River in southern France, is a masterpiece of Roman engineering. It wasn't built to transport people (though there is a pedestrian footbridge on it) - instead, it was part of a complex aqueduct system that carried water over 30 miles (about 50 km) to the ancient Roman city of Nemausus (now Nîmes).
10-The wedge-shaped stones, known as voussoirs, were arranged in three levels, the top-most being the water conduit. So precise was the engineering that the entire system descends only 56 ft. (17 m) vertically - over 30 miles! - to deliver 5 million gallons (20,00 m3) of water to the city.
