Completed in 1883, Brooklyn Bridge connects Manhattan and Brooklyn by spanning the East River. At the time it opened, and for several years, it was the longest suspension bridge in the world and it has become a famous and iconic landmark of New York. The bridge has a wide pedestrian walkway open to walkers and cyclists.
Golden Gate Bridge
The Golden Gate Bridge is a suspension bridge spanning the Golden Gate, the strait between San Francisco and Marin County to the north. The masterwork of architect Joseph B. Strauss, whose statue graces the southern observation deck, the bridge took seven years to build and was completed in 1937. The Golden Gate Bridge was the longest suspension bridge span in the world when it was completed, and has become one of the most popular tourist attractions in San Francisco and California. Since its completion, the span length has been surpassed by eight other bridges. The famous red-orange color of the bridge was specifically chosen to make the bridge more easily visible through the thick fog that frequently shrouds the bridge.
Ponte Vecchio
The Ponte Vecchio (literally “old bridge”) is a Medieval bridge over the Arno River in Florence; the only Florentine bridge to survive WW2. The bridge is famous for still having shops built along with it, as was common in the days of the Medici. Butchers initially occupied the shops; the present tenants are jewelers, art dealers, and souvenir sellers. It is said that the economic concept of bankruptcy originated here: when a merchant could not pay his debts, the table on which he sold his wares was physically broken by soldiers, and this practice was called “bancorotto” (broken table).
Tower Bridge
Tower Bridge is a combined bascule and suspension bridge in London, over the River Thames. It is close to the Tower of London, which gives it its name and has become an iconic symbol of London. Construction started in 1886 and took eight years to build. The bridge consists of two towers that are tied together at the upper level by means of two horizontal walkways which are designed to withstand the forces of the suspended sections of the bridge.
Sydney Harbour Bridge
Sydney Harbour Bridge is one of Australia’s most well known and photographed landmarks. It is the world’s largest (but not the longest) steel arch bridge with the top of the bridge standing 134 meters (440 feet) above Sydney Harbour. It took eight years to build and opened in March 1932. Because the steel expands or contracts depending on whether it is hot or cold the bridge is not completely stationary and can rise or fall up to 18 cm (7.1 inches).
Oresund Bridge
Oresund Bridge to Sweden leaving the island where Peberholm continues with a tunnel, Tunnel Drogden up in Denmark. Each of these three sections is a great technical achievement. The bridge itself, supported by cables, with the 7845 m long, is one of the largest buildings of its kind in the world with the largest opening (490 m) between the two legs that weighs 82,000 tons per meter. Although the ship traffic in the area takes place on the tunnel, the highest pillar is 204 m at the top is a four-lane road that passes under a railway double the average height of the bridge is 57 meters Peberholm Island there is a shift from the bridge to the tunnel. Peberholm is an artificial island built for this purpose, over 2 km long and several hundred meters wide, unpopulated, which belongs to Denmark. Drogden Tunnel starts from the middle of the island and after crossing the 3510 m under the sea, it continues with two tunnels of 270 m on land. The reason for which was built in place of the tunnel is another bridge that was too close to Copenhagen Airport.
