Osman Gazi the bridge connecting the Turkish city of Gavi with the province of yellow v''e was built by six different companies at once five of them were Turkish and one Italian and some other foreign partners were also involved this suspended construction 2682 metres long was erected in the narrowest part of the Gulf of ishm it the opening took place on July the 1st 2016 and thanks to its amazing size the bridge became the longest bridge in Turkey and the fourth longest suspension bridge in the world by the length of its central span in total the construction took about 39 months the giant weight of the bridge is supported by several 252 meter high supports the width of the roadway is 36 metres over 8,000 people worked on the construction of Osman Gazi about eleven billion dollars as well was spent on the construction it should be noted that Osman Gazi was built in one of the most earthquake-prone areas in the world therefore there were special requirements for reliability and durability to provide the bridge with increased stability the steel pylons were placed on a special concrete foundation the base in turn rests on a layer of gravel thanks to this design the pylons can slip slightly during particularly powerful earthquakes without endangering the entire structure also the bridge was equipped with built in seismic sensors that would raise an alarm in case of excessive vibration other sensors respond to the load of the road identify any even the smallest defamations so that they can be quickly detected and eliminated 85,000 tons of steel were use for the bridge and to prevent corrosion all metal parts were equipped with sensors for its detection hello girl and the construction of the bridge on the screen is still ongoing it started in February 2013 initially the opening was planned for spring 2018 but in the end it was postponed to October hello girl and is a suspension bridge crossing the fjord of ROM barkin located in Norway in the municipality of Narvik being a part of the european route ao6 it will allow to move around the country not only faster but also safer as roads in that area are exposed to snow avalanches its value is estimated at 2.2 billion Kronus at the time of construction a logger land is the longest suspension bridge in the Arctic Circle the length of the finished bridge will be 1533 metres at the same time the length of the central span is eleven hundred and forty-five meters the width of the road is 18 meters the government had to sign two separate contracts to build this road via ducks with a total length of 400 meters have a concrete surface the concrete surface will be covered with two layers of standard asphalt the part of the bridge located above the water is made of metal therefore it will be covered with another mixture resistant to water the bridge is held by two cables being 1621 meters long and 47 centimeters in diameter according to the engineers this design provides greater safety the supports of the bridge are 120 metres high and inside they have 1020 tonnes of reinforcement and more than 40 420 cubic meters of concrete were used for the erection youngster gang the construction of this bridge began in 2013 and it will end in 2019 it's located near the city of Wuhan where the Yangtze and Han rivers merge its unique feature is that it's a two-story bridge at the top of the bridge there'll be six road lanes and six more will be on the ground floor it's planned that after the completion of the construction the Yangtze Gang bridge also known as the stairway to heaven will become the longest two-story bridge in the world its length is four thousand three hundred and seventeen meters while the length of the main span is seventeen hundred meters in total the construction will take fifty four months with an investment of about eight thousand billion yuan this is a suspension bridge so the main supporting structure is made of flexible elements working on tension the roadway is suspended on it in this case the main load-bearing structure is constructed of steel cables folded into a single span metal track Maputo and this bridge is located in the south of mozambique when it stretches over the Maputo bay construction works began in 2014 and the opening was planned for June 25th 2018 but in the end it was postponed to the end of the year once completed Maputo will be the longest suspension bridge on the African continent it is interesting that the project was created several decades ago but the construction couldn't start because of problems with financing in the end the project was backed by the Chinese government and the Chinese road and bridge corporation is in charge of the construction according to China daily the project created 2,000 new jobs the bridge crosses the bay at an altitude of 60 meters its length is 3000 and 41 meters originally the pylons were going to be placed directly in the water but this would prevent shipping so the project was changed to thousand three hundred and sixty-one meters of the bridge is a viaduct that is the road rises above the land above the water there's a span of six hundred and eighty meters carrier cables are attached to anchor blocks from the north and the south side of the bay and the load on the structure would be extremely high so pile foundational platforms with a diameter from 1.5 to 2.2 meters are used the piles are deepened into mud stone at 110 metres the pylons have a height of 141 meters the carriageway is made of separate steel prefabricated parts each of them were set up in a factory in China and delivered to the Maputo Bay by ship these components have a width of 20 5.6 meters an electric 12 meters in total the construction of the bridge will cost 726 million dollars do J this bridge was also built in China it crosses the bye pan River and is located on the border of the city districts of Q Jing and Lu Han shui its total length is 1341 meters and the length of the main span is 720 meters it is the fourteenth longest main span in the world on a suspension bridge and the eighth in China it's amazing that the roadway is at a height of 564 meters above the river thanks to this the doogee is one of the ten highest bridges in the world it has a double peaked cable state structure and from the two sides it's replaced by sections of beam construction because of its unusual location the tower supports of the bridge have different heights the eastern one Rises 269 meters in the air and the western one 246 and a half meters to increase the stability and load carrying capacity of the structure it was decided to place a rod and frame system from below more than a thousand engineers and technicians took part in the construction this is one of the first suspension bridges built in Asia the construction began on September the 10th 2013 and on December the 29th 2016 the bridge was put into operation
