The Tallest Rail Bridge in the World – Chenab River Arch Bridge

Introduction
On 5th April 2021, Indian Railways completed the construction of the World’s highest railway bridge. This bridge is located in the union territory of Jammu and Kashmir and is a part of the Udhampur-Srinagar-Baramulla rail link project (USBRL). The length of the bridge is 1,315 meters, and it stands 359 m above the riverbed, which makes it the world’s highest railway bridge.

In July 2008, the bridge’s construction was stopped after concerns about its safety and alignment were raised. A seven-member expert committee led by former Chairperson of the Board of Railways, M. Ravindran, had been established to deal with the issue. After so many alterations and testings, the construction of this bridge was finally completed making it the tallest railway bridge in the world.
