Hardanger Bridge, Norway

Hardanger Bridge is a suspension bridge across the Hardangerfjorden in Hordaland county, Norway. The bridge connects the municipalities of Ullensvang and Ulvik. It replaced a ferry connection between Bruravik and Brimnes, and thereby shortens the driving time between Oslo and Bergen. It is the longest suspension bridge in Norway.

The bridge was approved for building by the Norwegian Parliament on February 28, 2006, and construction began on February 26, 2009.While the bridge was engineered by the Norwegian Public Roads Administration, the construction is done by MT Højgaard.The project had a budget of NOK 2.3 billion (€290 million) and more than half of this will be paid by toll and saved ferry subsidies.The Administration is considering a different route over a future bridge as the main connection between East and West.

The ferry, serviced by Fjord1, ran across the fjord every 20–60 minutes depending on the season, and the trip lasted 10 minutes.

The bridge is 1,380 metres (4,530 ft) long, with a main span of 1,310 metres (4,300 ft). Sailing height is 55 metres (180 ft) and the towers reach 200 metres (660 ft) above sea level. There are two driving lanes for cars with an 80 kilometres per hour (50 mph) speed limit, and a separate lane for pedestrians and cyclists.

The traffic predicted for the bridge was only estimated to be 2000 vehicles per day. The opening of the bridge took place on 17 August 2013.

The main span is one of the longest suspension bridge spans in the world. It is also the longest tunnel to tunnel suspension bridge in the world. On the south end of the bridge, cars immediately enter the 1.2-kilometre (0.75 mi) Bu Tunnel that goes under the village of Bu and on the north side of the bridge, cars immediately enter the 7.5-kilometre (4.7 mi) Vallavik Tunnel which includes a 500-metre (1,600 ft) long segment to a roundabout inside the tunnel. At the roundabout, cars can take another 500-metre (1,600 ft) long tunnel that leads to Ulvik or they can take a 7-kilometre (4.3 mi) long tunnel to Granvin.

Second longest cable stayed bridge in North America-Port Mann Bridge

The widest bridge in the world (until the Bay Bridge's east span recently opened), the bridge east of Vancouver, B.C., which opened in 2012, remains the second-longest bridge in North America. The cable-stay bridge uses an impressive 288 cables to reach a total bridge length of 6,866 feet. The Port Mann Bridge is a 10-lane cable-stayed bridge that opened to traffic in 2012. It is currently the second longest cable-stayed bridge in North America and was the widest bridge in the world until the opening of the new Bay Bridge in California . The new bridge replaced a steel arch bridge that spanned the Fraser River , connecting Coquitlam to Surrey in British Columbia near Vancouver . The old bridge consisted of three spans with an orthotropic deck carrying five lanes of Trans-Canada Highway traffic, with approach spans of three steel plate girders and ...

FALKIRK WHEEL

The Falkirk Wheel is a rotating boat lift in Scotland. It connects the Forth and Clyde Canal with the Union Canal. Named after the nearby town of Falkirk in central Scotland, the lift opened in 2002. The two canals it serves were previously connected by a series of 11 locks, but by the 1930s these had fallen into disuse. The locks were filled in and the land built upon. The plan to regenerate central Scotland's canals to reconnect Glasgow with Edinburgh was led by British Waterways with support and funding from seven local authorities, the Scottish Enterprise Network, the European Regional Development Fund, and the Millennium Commission. Planners decided early on to create a dramatic 21st-century landmark structure to reconnect the canals, instead of simply recreating the historic lock flight. Designs were submitted for a boat lift to link the canals; the Falkirk Wheel-design...

Design, Construction & Structural Details of Burj Khalifa

The goal of the Burj Dubai Tower is not simply to be the world's highest building: it's to embody the world's highest aspirations. The superstructure has reached over 165 stories. The final height of the building is 2,717 feet (828 meters). The height of the multi-use skyscraper has "comfortably" exceed the previous record holder, the 509 meter (1671 ft) tall Taipei 101. The 280,000 m 2 (3,000,000 ft 2 ) reinforced concrete multi-use Burj Dubai tower is utilized for retail, a Giorgio Armani Hotel, residential and office. As with all super-tall projects, difficult structural engineering problems needed to be addressed and resolved. Structural System Description Burj Khalifa has "refuge floors" at 25 to 30 story intervals that are more fire resistant and have separate air supplies in case of emergency. Its reinforced concrete structure makes it stronger than steel-frame skyscrapers. Designers purposely shaped the st...
