Construction Starting

The Chenab Rail Bridge was originally intended to be completed in December 2009. However, in September 2008, the project was halted 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.

Design and Technology

The design and construction was awarded to Afcons Infrastructure, a part of the Shapoorji Pallonji Group, the third-largest construction group in India, with the help of IISc Bangalore. Major construction decisions were taken by Konkan Railway Corporation. The Defence Research and Development Organisation (DRDO) helped in the design of the bridge, making it blast-proof using special steel.

Regular painting of large bridges is an intimidating task; hence, a painting scheme was developed, having renewal of over 15 years, compared to approx. 5 to 7 years in most other Indian railway bridges.
