01.The Golden Gate Bridge
The Golden Gate Bridge is a one-mile-wide suspension bridge connecting the Gulf of San Francisco and the Pacific Ocean.
Believe it or not, many were opposed to building a symbolic milestone that would dramatically connect San Francisco to Marin. When the original design for the Golden Gate Bridge by engineer Joseph Strauss was revealed in 1922, the press declared it “ugly” and architects suspected that its long suspension bridge might be structurally good. The magnificent Golden Gate Bridge opened on May 27, 1937, despite objections.
The Golden Gate Bridge we know and love is in a beautiful Art Deco style. Strauss collaborated with architect Irwin Morrow to select the bridge’s color, international orange, based on how it would contrast with the surrounding land, sea, and fog. If you think about it, painting a bridge is a continuous process that takes place throughout the year to protect it from corrosive salty bay air. The Golden Bridge is named after the Golden Gate Strait, the entrance between the Pacific Ocean and the Gulf of San Francisco.
Today, the Golden Gate Bridge is considered one of the Seven Wonders of the World. The bridge draws about 10 million people each year and is a major motivation for them to come to Presidio. It connects visitors to other sites in the Golden Gate National Recreation Area in the north.
02.London Tower Bridge
Built between 1886 and 1894, Tower Bridge is a Grade-listed combination basque and suspension bridge in London, designed by Horace Jones and built by John Wolf Barry. The Bridge House Estate, founded in 1282, owns and operates five London bridges, one of which spans the Thames near the Tower of London. The bridge was built to provide better access to the east corner of London. Its commercial potential expanded in the 19th century. Princess Edward of Wales and Princess Alexandra of Wales inaugurated the bridge in 1894.
The bridge is 800 feet (240 m) long and consists of two 213 (65 m) bridge towers connected by two high-level horizontal walkways and a pair of central baskets that can be opened to shipping. Originally powered by hydraulics, the operating mechanism was converted to an electric hydraulic system in 1972. 40,000 crossings every day. The Tower Bridge Exhibition comprises the bridge’s two towers, elevated walkways, and Victorian Engine Room, and is available to both automobiles and pedestrians.
Tower Bridge has become a landmark in London. It may have been confused with London Bridge, mile 0.5 (0.80 kilometers), about the rise, American has given rise to a popular urban legend about buying the wrong bridge. Several stunt pilots, including pioneer Francis McLean, have flown under the bridge.
03.The Rialto Bridge-Vanice
The Rialto Bridge is the oldest of the four bridges over the Great Canal of Venice, Italy. It connects the San Marco and San Polo neighborhoods and has been renovated multiple times since its original erection as a Pontoon Bridge in 1173. It is currently a major tourist attraction in the city.
The first dry crossing of the Gr?? nd Canal was the Pontoon Bridge, built-in 1181 by Niccol ?? Barteri. It Moneta Ponte Della known as, the mint that was near the eastern entrance to the bank hæka.nægenahira riyal? o market development and the importance of increased traffic due to the floating bridge, so it is 1255 in a wooden bridge was replaced. The structure had two slopes in the middle of the movable section, which could be lifted to allow higher ships to navigate. The connection with the market eventually led to the name change for the bridge. 15In the early part of the twentieth century, two rows of shops were built on either side of the bridge. The rent brought in revenue to the state treasury, which helped maintain the bridge.
Antonio da Ponte designed the existing single-span stone bridge, which was built in 1588 and finished in 1591. It is similar to a successful wooden bridge. Two slopes lead to the central portico. On either side of the portico, there are rows of shops on the covered slopes. Bridge engineering was regarded as so bold because architect Vincenzo skæmosi predicted future destruction. The bridge has challenged its critics to become one of Venice’s architectural icons and a top tourist attraction.
04.Sydney Harbor Bridge
Sydney Harbor Bridge is a steel arch bridge across the heritage-listed in Sydney and, from Sydney, Central Business District extends from the northern coast. The Sydney Opera House, the bridge, and the surrounding harbor landscape are widely considered symbols of Sydney and Australia.
Under the guidance of John Broadfield of the New South Wales Public Works Department, the bridge was designed and built by a British company, Doman Long of Middlesbrough (based on their 1928 Newcastle Open Tyne 1928 Tyne Bridge) and opened in 1932. The general design of the bridge, which Broadfield was responsible for producing for the NSW Department of Public Works, is a rough copy of the Hellgate Bridge in New York City. However, this general design document did not formulate any part of the bid for the tender, and it was wide enough to allow for cantilever (Broadfield’s original preference) and even suspension bridge proposals. Design selected from tender responses Dorman LongCreated by the original design, and, on their Tyne Bridge from using the design, the surface is similar, Harbor Bridge arch into every corner of the beautiful flames that does this. At 134 meters (440 feet) above sea level, it is the world’s eighth-longest arch bridge and the world’s highest steel arch bridge. It was also the world’s longest bridge at 48.8 (160) m. Ft) wide, until the completion of the new Port Man Bridge in Vancouver in 2012. On March 19, 2007, the Sydney Harbor Bridge was listed on the Australian National Heritage List, and on June 25, 1999, it was placed on the New South Wales County Heritage List.
05.The Millau Viaduct-France
The Millau Viaduct is a multi-span cable-stayed bridge in Millau, in the Aveyron department of the Occitanie Region of Southern France, that was completed in 2004. It crosses the Tarn canyon valley in Millau. Engineer Michel Virlogeux and English architect Norman Foster headed the design team. It will be the world’s highest bridge by September 2020, with a structural height of 336.4 meters (1,104 ft).
The Millau Viaduct connects Paris to Béziers and Montpellier along the A75 – A71 autoroute axis. The cost of construction was approximately 39? 394? Million ($ 424 million). It took three years to build and was officially inaugurated on December 14, 2004, with traffic opening two days later on December 16, 2004. The bridge has regularly been recognized as one of the most significant engineering feats of modern times, and it was awarded the 2006 Outstanding Structure Award by the International Association for Bridge and Structural Engineering.
