Bridges have been an effective part of transportation ever since humans started to move their goods and themselves from one place to another. In the beginning, engineers only have to do little more than fall a tree across a river or stream, but now they have discovered that bridges could cut across vast distances and more massive load by taking more time and putting more effort into the structures. In recent years, engineers have pushed the limit of design, innovation, imagination, and engineering to the point where we can put bridges at anywhere. Some bridges span rivers, traverse mountain ranges, connect countries, high above jungles and even connect continents. Here are some of the best-engineered buildings in the world.
OCTAVIO FRIAS DE OLIVEIRA BRIDGE, BRAZIL
Located in Sao Paulo, this x-shaped, cable-stayed bridge was completed in 2008 over the Pinheiros River. An unusual feature of this bridge is its two levels of traffic cross one another as they move along the central entrance. The arch, 452 feet high is holding things up and fascinating too. The total length of the bridge is just a mile shy. Series of 144 steel cables were used to enhance the structure. The masterpiece deserves all the expenses spent on it. With a Philips designed led lights that display the bridge in changing patterns and colors, the bridge lights up like the 4th of July.
HANGZHOU BAY BRIDGE, CHINA
Spanning over 22 miles long, the Hangzhou Bay Bridge is regarded as the longest ocean-crossing bridge in the world. The massive structure mixes cable-stayed spans, and conventional highway bridge elements were completed in 2008 after about ten years of planning. It links the cities of Ningbo and Jiaxing, and reduce the commute between them by 75 miles. The engineers that constructed this massive structure took note of its powerful typhoons and strong tides. The bridge is a bit S-shaped, and it helps to withstand the intense flows. Plans for the bridge include a service area in the middle of the bridge.
GATESHEAD MILLENNIUM BRIDGE, ENGLAND
The Gateshead Millenium Bridge is an award-winning tilt-bride that is created by Wilkinson Eyre. The bridge has a system of hydraulic rams that can pivot the bridge’s walkway at an angle of 40 degrees to allow a boat pass. Wilkinson describes the movement of the building as looking like a slowly opening eyelid, and the process takes about 5 minutes. Another fascinating thing about the bridge is that it was installed already built, by using the most significant floating crane in Europe the Hercules II.
GOLDEN GATE BRIDGE, SAN FRANCISCO
Regard as one of the wonders of the Modern world by the American society of civil engineers, and the golden gate bridge is the most photographed building in the world. As at 1937 when built, it was regarded by some as the most beautiful in the world. The bridge connecting San Francisco to other bay communities. Though lots of experts say it can’t be done due to the smothering fogs, the golden gate bridge became a bridge to reckon with after construction.
