The Dhaka Times Desk Taking another step forward in the excellence of technology and science, the deepest railway line has been built under 190 feet of water in Istanbul, Turkey. It will connect the city of East and West Istanbul.
The Marmaray Tunnel, built under the sea in Istanbul, Turkey, is the world's first tunnel to connect two continents by rail. The entire tunnel is 8.5 miles long and was unveiled on Turkey's 90th Independence Day.
The tunnel project started in 2005 and was supposed to be completed in 2009, but due to various complications, its completion was delayed. The tunnel is built with a strong earthquake resistant system and is the deepest tunnel in the world in terms of volume and depth.
Meanwhile, Istanbul city officials said they expect approximately 1.5 million people to ride the tunnel's rail daily to travel by rail. At present, all the traffic in the city of Istanbul is traveling to the city on the other side of the river by the bridge over the tunnel, which puts a lot of pressure on the city's traffic system. Officials also hope that the new Marmaray Tunnel will significantly improve Istanbul's traffic system. Meanwhile, the Turkish government has special future plans for the Marmaray Tunnel, which could be used as a link between Southern Europe and China.
Many researchers were worried that the Marmara tunnel might be particularly damaged in an earthquake because it is located in an earthquake-prone area, but the tunnel manufacturer has informed that there is no danger because the tunnel has been built with enough earthquake resistance. It can withstand earthquakes of more than 9.0 on the Richter scale, authorities said.
If all goes well, the Marmare Tunnel is expected to sit at a unique height among the underground tunnels built so far.
