Arches of Iconic Chenab Bridge in J&K Joined

The Indian Railways has completed the Arch closure of the iconic Chenab Bridge, which is world’s highest railway bridge being constructed over Chenab

The Indian Railways has completed the Arch closure of the iconic Chenab Bridge, which is world’s highest railway bridge being constructed over Chenab River in Jammu and Kashmir at an estimated cost of INR 1,486 crores and is a part of the Udhampur-Srinagar-Baramulla Rail Link project. A 6 metre long last piece of steel structure was fitted at the highest point joining the two arms of the arch stretching from both the banks of the river. After completion of the arch work, removal of the stay cables, filling of the concrete in the arch rib, erection of the steel trestle, launching of the viaduct and track laying work will be taken up

This bridge is 1315 meter long and is the highest Railway Bridge in the world being 359 meter above the river bed level. Construction of the bridge involved the fabrication of 28,660 tonnes of steel, 1 million cubic meters of earthwork, 66,000 cubic meters of concrete and 26 kilometres motor able roads. Arch consists of steel boxes. Concrete will be filled in boxes of the Arch to improve stability. Approximately 584 kilometres of welding was done to join the different parts of structure. The estimated cost of the bridge is INR 1,486 crores

The bridge is designed for blast load in consultation with the Defence Research and Development Organisation. It can remain operational at a restricted speed of 30 kilometers per hour after removal of one pier or trestle. The bridge is designed to withstand high wind speed of up to 266 kilometers per hour and earthquake forces of highest intensity. Sophisticated Tekla software was used for structural detailing and structural steel is suitable for minus 10 degree celcus to 40 degree celcus temperature. Indian Railways used phased array ultrasonic machines and established a NABL-accredited lab at the site for weld testing
