The Juscelino Kubitschek Bridge spans Lake Paranoa in Brasilia, Brazil, and is made of steel and concrete. The primary span is supported by four underwater pillars, while the deck weight is carried by three 200-foot-tall (61-meter) asymmetrical steel arches that crisscross diagonally over the bridge. The total length of the bridge is 5,880 feet (1,813 meters), and it was completed in 1995 at a cost of $63 million.
This bridge is most famous for being the object of controversy when it was proposed. At the time, it was the largest single-span concrete arch bridge in the world. The proposal caused concern among some environmentalists because they believed it would destroy a natural habitat. However, it was approved by local authorities despite these objections.
The main reason for building this bridge was to provide access to a new international airport being constructed about 25 miles (40 kilometers) to the east of Brasilia. The bridge also serves as one of two main entrances into the city from the east. The other entrance is provided by another new bridge called the Tancredo Neves Bridge, which crosses the Rio Grande da Encarnação near the end of Tijuca National Park.
In addition to its many critics, this bridge has been subject to claims of plagiarism.
Chan, Alexandre Vila Verde, Mario Juscelino Kubitschek Bridge/Kien truc su The 1,200-metre-long cable-stay bridge was designed by Brazilian architect Alexandre Chan in conjunction with structural engineer Mario Vila Verde and completed in 2002. It links Rio de Janeiro to Guanabara Bay at Leblon.
The bridge is named after its designer, who was also president of Brazil from 1956 to 1961. It connects the city's North Side to the South Side via the Avenida Brasil highway. The bridge has three traffic lanes for cars and trucks as well as two sidewalks for pedestrians. Its total length is 1,200 meters (1 mile).
It is one of the most expensive bridges in the world when cost per meter is considered. The main span is 300 meters long and it takes about 20 minutes to cross from one side to the other at a speed of 30 km/hr (19 mph). There are plans to build another Chan bridge next to this one so people can travel back and forth easily between the two cities.
This bridge replaced an old swing bridge that used to connect these two parts of Rio de Janeiro. The new bridge was needed because many vehicles were using the old road that went through Morro do Diabo (Rocks of Hell), a steep hill on which there are several caves.
Bridge Juscelino Kubitschek/Ngay/nam khoi cong, 2000. The Juscelino Kubitschek bridge is a cable-stayed bridge that spans the Tietê River in Brazil. It connects the cities of Paraíso and Odivelas, both part of the Greater Lisbon metropolitan area. The bridge has two main sections: the north section has four lanes for motor vehicles and two lanes for buses, while the south section has three lanes for motor vehicles and one lane for buses.
It is named after its architect, who also designed the similar Marcelo Tas Bridge across the Douro river in Portugal. The Kubitschek bridge is the largest single-span steel structure in South America.
It took more than five years to build this bridge at a cost of $70 million (R700 million). The project was launched in 1995 and completed in 2000. The north section of the bridge opened to traffic the same year while the south section did so six months later. The bridge has been praised for its design and environmental awareness with its waste water being reused for irrigation purposes.
