Sydney Harbor Bridge is one of the main landmarks in Sydney, Australia, Sydney connecting the central business district (CBD), on the north shore commercial and residential areas, who are both with headquarters in Sydney Harbor. Spectacular views of the water from the bridge, along with the proximity of Sydney Opera House is an iconic image of Sydney and Australia. The bridge is gently known as “Coathanger” due to its arch-based design.

The bridge was the city the highest structure before 1967. It is the largest bridge in the world. It is the world’s largest single arch bridge, but no more (in million Australian school children mistakenly). The bridge was officially opened on March 19, 1932. Bayonne Bridge in the United States of America, opened four months ago, on 15 November 1931, 70 cm (or 2.3 feet) long.

The design has a strong resemblance to that in Hell Gate Bridge in New York. The design was used as a basis for the Tyne Bridge in Newcastle upon Tyne, England, which is almost identical, except for the small scale.

Ponte Vecchio is a medieval bridge over the River Arno. Indeed, it is much more than a bridge – this street markets, as well as a milestone in Florence, Italy.

Ponte Vecchio that we know today, was in 1345 by Taddeo Gaddi after more than age was destroyed in the floods. To finance the bridge, many along the street were rented to traders, especially butchers and tanners to Hok their products.

In 1565, Duke Cosimo I de Medici ordered the architect Giorgio Vasari described the construction of the roof of the corridor. Shortly thereafter, jewelers, silversmiths and traders of luxury prompted butcher of the Ponte Vecchio. Centuries of random additions gave the bridge of the distinctive, irregular appearance today.

During World War II, companies, many of the floods, the bridges facing the most serious threat: German bombers were to blow up a bridge in Florence. There is a direct order from Hitler that spared Ponte Vecchio from certain destruction.

This suggests that the word “bankruptcy” came from Ponte Vecchio. If the trader does not pay its debts, the table (the “Bank”) to sell its product has been broken ( “art”) by soldiers. You do not have images ( “bancorotto”), means that the seller is in bankruptcy.

Covered Bridge just that: bridges that the parties have been closed, and the roof. Although technically Most Sigh, Ponte Vecchio, and the wind and rain bridges on the list are under bridges, the term usually means a simple one lane bridges in rural areas.

Before that was made famous in the 1995 Clint Istvud film bridges in Madison County “, KISSING bridges” or “Tunnel of Love” is the pride and joy of many small towns throughout Europe and North America, where over ten thousand of these bridges were built .

In the 19 century, wood was plentiful and cheap (or, in many cases free of charge). It is therefore natural that these bridges are made of wood. But why do they cover? Well, except for fans, the real reason was more practical: a wooden beam bridge lasted longer if the elements.

Unfortunately, because of neglect, timber theft, vandalism and fire, mainly bridges, covered in the United States and Canada, have disappeared.

The Iron Bridge, located on the River Severn in Shropshire, England, is not particularly large or ornate bridge, but he has something unique: the first bridge made entirely of iron.

In the 18 th Century, Shropshire is rich in iron and coal – in fact there is more iron factories during the two-mile radius of the city than any other city in the world. He was also there, which will melt iron with coke. It is therefore natural that the bridge would be iron, a strong alternative to wood.

Farnolls architect Thomas Pritchard, a proposal for an arched bridge, in a boat, but died before the bridge was built. Construction of the iron bridge was built by a local craftsman Ironworkers named Abraham Darby III. About 400 tons (363 tons) of iron was used, with about 800 molded separately. The Iron Bridge has 5 arch ribs, each cast in two halves. Only lasted for three months to piece together (which, to use screws instead of bolts).

The ease and speed of the iron bridge under construction has helped convince engineers versatility and durability of cast iron, and contributed to Usher in the era of the Industrial Revolution. Derby, but not so well: he badly underestimated the cost of building the bridge, and remained indebted to the rest of their lives

In the 19 th century, Lord Byron named Venetian limestone bridge over the Rio di Palazzo connecting doge from prison for interrogation room in the main palace, Bridge of Sighs (Ponte dei Sospiri). Alleged that prisoners who sigh when they go out the window – with stone bars no less – to show their latest look at the beautiful Venice before imprisonment, torture or execution.

Pont du Gard, running water, the river Gard in southern France, the masterpiece of Roman engineering. It was built to carry passengers (although there are pedestrian walkway in the same) – instead of a part of a complex aqueduct system, which led to water more than 30 miles (50 km) on ancient Roman city of Nemausus (NIMES now).

Pont du Gard was Marcus Vipsanius Agrippa (63 to 12 BC), son of Emperor Augustus. A stone bridge, some of which weigh up to 6 tons, were reduced under perfectly together without mortar.

Wedge-shaped stones, known as voussoirs, were divided into three levels, is the tip of most water pipes. Thus, she stated that the construction of the entire system is only 56 feet (17 m) vertically – more than 30 miles! — Deliver 5 million gallons (20.00 m3) of water in the city.

Khoju The bridge consists of two stories of arcades, the intersection of the distinctive arches richly decorated with colored tiles. In the middle of the bridge, there are two large halls, called Prince salons, originally developed for the Shah.
