GS Paper - 2 Infrastructure
Taking a major leap towards the completion of the 111 kilometre long winding stretch from Katra to Banihal, on 5 April 2021 the Northern Railway zone has completed the Arch closure of the world’s highest railway bridge, Chenab Bridge in Jammu and Kashmir. The iconic Chenab Bridge is a part of the Udhampur-Srinagar-Baramulla rail link (USBRL) project and the completion of the steel arch was one of the most difficult parts of the bridge over Chenab.
Salient features of the Chenab Bridge
- The iconic Arch Bridge on River Chenab is being constructed by Indian Railways as a part of the USBRL project to link the Kashmir valley to the rest of India.
- The iconic bridge is 1315 metres long and is the world’s highest railway bridge being 359 metres above the river bed level.
- The Arch of the Chenab Bridge will be 35 meters higher than the Eiffel Tower in Paris.
- Bridge construction involved the fabrication of 28,660 million tonnes steel, 10 lakh cum earthwork, 66,000 cum concrete as well as 26 kilometres motorable roads.
- The Arch comprises steel boxes. In order to improve stability, concrete will be filled in boxes of the Arch.
- The overall weight of Arch is 10,619 million tonnes.
- For the first time, erection of the members of the arch by overhead cable cranes was done on the Indian Railways network.
- For structural detailing, the most sophisticated ‘Tekla’ software was used.
- Structural steel is suitable for temperature from -10°C to 40°C.
