The Russki Island bridge has a world record trick: span length
Sometimes it seems that the question is that no bridge is built in vain in terms of meeting a world record, and in this case never better expressed given the quality in which this construction is world champion. The Russki Island Bridge It is not the longest in its class or the tallest, but it manages to carve a niche in the multiple rankings those who aspire to these mega-constructions (We are not talking about small bridges).
The one on Russki Island is the world’s longest span cable-stayed bridge. Until the impressive Millau Viaduct It was also the bridge of this type with the highest piers, 320 metersBut the construction across the Tarn Valley took that gold from him by climbing up to 343 meters.
From Russia with dough
Russia is the largest country in the world, it touches several oceans and seas and with thousands of kilometers of coastline (and more than 50 islands) it is quite suitable for long bridges. While the idea of creating a bridge spanning Alaska and Russia’s easternmost point (though perhaps there was at some point in history, Russians have been building bridges in less demanding environments and with good timing if we talk about the one on Russki Island. Of course, nothing is coincidence.
Russki Island is a geographical formation located in the Sea of Japan, about 600 meters from the mainland of Vladivostok, city under whose administration it is. Between the island and the Russian city there is the so-called Eastern Bosphorus Strait, so that the bridge connects this island with the continental mass.
This island, about 96 square kilometers in area, had some importance military during the Soviet era, serving as a stronghold for Vladivostok to the south. After the war conflicts in the area, the strategy with it is different and the interest was focused on increasing the value of it as a tourist resource.
The idea? Simple: there is no shorter distance between two points than a straight line. So building a bridge over those 600 meters became an attractive and colorful solution that It could also fix certain political-economic issues.
As he wrote The Economist in 2012, after its inauguration, the bridge was “a symbol Moscow’s plans for the development of the eastern tip of Russia and for closer ties with Asia, the ‘most important geopolitical task’ according to President Vladimir Putin. according to some visitors, that they consider it as beautiful as “useless”.
Leaving aside the historical context of its construction, the fact is that they got down to work to create this structure whose dimensions, despite not being mostly in world records, do not go unnoticed either. The shortest coast-to-coast distance is 1,460 meters, measuring 1,885 kilometers in length and those 320 meters that we have discussed in height of the towers.
Its length is not close to 164 kilometers from the longest bridge in the world (in China, where would it be if not), but almost better. We are talking about an area with a very wide thermal oscillation, being able to go from 37 degrees Celsius to -31ºC.
Ice (reaching more than 70 centimeters thick above the sea) and snow are not the only climate-related difficulties that this structure has to endure. The area is hit by typhoons that can reach 100 kilometers / hour and the waves reach six meters.
The central section of the bridge is the protagonist: beyond the views it has, its central section suspended by cables is of 1,104 meters (that is, the span length, which as defined by the RAI is the horizontal distance between the conductor attachment points in two consecutive supports).
The Russki Island Bridge was built within the framework of the Asia-Pacific Economic Cooperation Conference (APEC), which took place on the same island in September 2012, the year of its inauguration. A work that cost about $ 1.1 billion (from that moment), forming part of the pinch that the summits cost (about 20,000 million).
