Hello my lovelies, i know have been a little bit MIA lately due to school projects but to make it to you guys, lets talk about bridges…
Breathtaking bridges in the world…
Golden Gate Bridge: San Francisco, United States
The Golden Gate Bridge is a suspension bridge spanning the Golden Gate, the one-mile-wide (1.6 km) strait connecting San Francisco Bay and the Pacific Ocean.
It opened in 1937 and was, until 1964, the longest suspension bridge main span in the world, at 4,200 feet (1,280 m).
San Francisco’s City Engineer estimated the cost at $100 million, which would have been $2.12 billion in 2009, and impractical for the time. Joseph Strauss was an ambitious engineer and poet who had, for his graduate thesis, designed a 55-mile-long (89 km) railroad bridge across the Bering Strait. Strauss which promised could be built for $17 million.
Construction began on January 5, 1933. The project cost more than $35 million, completing ahead of schedule and $1.3 million under budget. The Golden Gate Bridge construction project was carried out by the McClintic-Marshall Construction Co., a subsidiary of Bethlehem Steel Corporation founded by Howard H. McClintic and Charles D. Marshall, both of Lehigh University. 1.2 million steel rivets hold the bridge together. This is a segment of one of those replaced during the seismic retrofit of the bridge after the 1989 Loma Prieta earthquake.
Strauss remained head of the project, overseeing day-to-day construction and making some groundbreaking contributions.
Sydney Harbour Bridge: Sydney, Australia
The Sydney Harbour Bridge is a steel through arch bridge across Sydney Harbour that carries rail, vehicular, bicycle, and pedestrian traffic between the Sydney central business district and the North Shore. The dramatic view of the bridge, the harbour, and the nearby Sydney Opera House is an iconic image of Sydney, and Australia. The bridge is nicknamed “The Coathanger” because of its arch-based design. It is the sixth longest spanning-arch bridge in the world and the tallest steel arch bridge, measuring 134 m (440 ft) from top to water level. It was also the world’s widest long-span bridge, at 48.8 m (160 ft) wide, until construction of the new Port Mann Bridge in Vancouver was completed in 2012.
Construction started: 28 July 1923
Opened: 19 March 1932
Ponte Vecchio: Florence, Italy
The Ponte Vecchio is a medieval stone closed-spandrel segmental arch bridge over the Arno River, in Florence, Italy, noted for still having shops built along it, as was once common. Butchers initially occupied the shops; the present tenants are jewelers, art dealers and souvenir sellers. The Ponte Vecchio’s two neighbouring bridges are the Ponte Santa Trinita and the Ponte alle Grazie.
Ponte Vecchio is the oldest bridge in Florence, Italy and one of the oldest bridges in Europe and in the world. It has long and rich history.
Total length is about 95m
Brooklyn Bridge: New York City, United States
Completed in 1883, the Brooklyn Bridge is one of the oldest suspension bridges in the United States. A National Historic Landmark, the Brooklyn Bridge is an iconic feature of New York.
Started in 1869 and completed fourteen (14) years later in 1883, it connects the boroughs of Manhattan and Brooklyn by spanning the East River.
Gateshead Millennium Bridge: Gateshead, England
Tsing Ma Bridge: Hong Kong, China
Tsing Ma Bridge is a bridge in Hong Kong. It is the world’s 11th-longest span suspension bridge, and was the second longest at time of completion. The bridge was named after two of the islands at its ends, namely Tsing Yi and Ma Wan. It has two decks and carries both road and rail traffic, which also makes it the largest suspension bridge of this type. The bridge has a main span of 1,377 metres (4,518 ft) and a height of 206 metres (676 ft). The span is the longest of all bridges in the world carrying rail traffic.
The 41-metre-wide (135 ft) bridge deck carries six lanes of automobile traffic, with three lanes in each direction. The lower level contains two rail tracks and two sheltered carriageways used for maintenance access and traffic lanes when particularly severe typhoons strike Hong Kong and the bridge deck is closed to traffic.
Akashi-Kaikyo or Pearl Bridge: Kobe-Naruto, Japan
The Akashi Kaikyō Bridge (明石海峡大橋 Akashi Kaikyō Ō-hashi) is a suspension bridge, which links the city of Kobe on the Japanese mainland of Honshu to Iwaya on Awaji Island. It crosses the busy Akashi Strait (Akashi Kaikyō in Japanese) as part of the Honshu–Shikoku Highway. It was completed in 1998, and has the longest central span of any suspension bridge in the world, at 1,991 metres (6,532 ft; 1.237 mi). It is one of the key links of the Honshū–Shikoku Bridge Project, which created three routes across the Inland Sea. There is a tour 4 days a week from April to November which participants can learn the history in detail and go up to the top of the tower on the bridge which is about 300m in height.
