Chenab Bridge is the highest railyway bridge in India and the whole world. Chenab Bridge is an under-construction rail bridge, located between Bakkal and Kauri in the Reasi district of Jammu and Kashmir (J&K), India. The 1,315m-long bridge is being built at a height of 359m. Once completed, it will be the tallest rail bridge in the world.
The INR5.12bn ($92m) bridge is a part of Jammu-Udhampur-Srinagar-Baramulla Rail Line (JUSBRL) project being undertaken by the Ministry of Indian Railways. The bridge will include a 14m-wide dual carriageway and a 1.2m-wide central verge.
After completion, the bridge will span the Chenab River at a height of 359 m (1,178 ft) above the river, making it the world’s highest rail bridge.

Chenab Bridge Completion Data
At the initial stage, Chenab Bridge was originally intended to be completed in December 2009. However, in September 2008 the project was stopped due to fears over the bridge’s stability and safety.
Work on the bridge restarted in 2010 with the plan to complete it in 2015 but could not be completed in 2015. The project is expected to be finished by March 2016 and will have a lifespan of 120 years.
Chenab Bridge forms a massive steel arch, the first of its kind in India. The country has no codes or design guidance for such massive structures.
The bridge will include 17 spans, as well as the 469m main arch span across the Chenab River, and viaducts on either side. The main span of the bridge will include two 36m-long approach spans. It will be built as a two ribbed arch with steel trusses made of concrete-filled sealed steel boxes. The structure will be supported by two 130m-long, 100m-high pylons on either end through cables.
Steel was chosen to construct the bridge as it will be more economical and able to resist temperatures of -20C and wind speeds of above 200kmph. The Jammu and Kashmir region witnesses frequent terrorist attacks. To enhance safety and security, the bridge will be made of 63mm-thick special blast-proof steel. The concrete pillars of the bridge are designed to withstand explosions.
