Railways complete the Arch closure of the iconic Chenab Bridge, World's highest Railway Bridge




The Arch looms over Chenab, flowing 359 metres below

Arguably the biggest civil-engineering challenge faced by any railway project in India in recent history

Major Leap towards completion of the Katra- Banihal section

Indian Railways today completed the Arch closure of the iconic Chenab Bridge.

Chenab Bridge, the world's highest railway bridge, part of the Udhampur-Srinagar-Baramulla rail link project (USBRL), set an important construction milestone today with completion of the steel arch of the iconic Chenab Bridge. This was o­ne of the most difficult part of the bridge over Chenab. This achievement is a major leap towards the completion of the 111 k.m. long winding stretch from Katra to Banihal. It is arguably the biggest civil-engineering challenge faced by any railway project in India in recent history. The 5.6-metre last piece of metal was fitted at the highest point today and joinedthe two arms of the arch that currently stretch towards each other from both the banks of the river. This completed the shape of the arch that will then loom over the treacherous Chenab, flowing some 359 metres below. 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.

The completion of the historic Arch work was also seen by Shri Piyush Goyal Minister for Railways, Commerce & Industry and Consumer Affairs, Food & Public Distribution, Shri Suneet Sharma, Chairman & CEO, Railway Board, Shri Ashutosh Gangal, General Manager Northern Railway through video conferencing.

·This bridge is 1315m long.

·This is the highest Railway Bridge in the world being 359m above the river bed level.

·It will be 35 meters higher than the iconic Eiffel Tower in Paris (France).

·Construction of Bridge involved fabrication of 28,660 MT steel, 10 Lakh Cum Earthwork, 66,000 Cum Concrete and 26 Km motorable roads.

·Arch consists of steel boxes. Concrete will be filled in boxes of the Arch to improve stability.

·Overall weight of Arch is 10,619 MT.

·Erection of the members of arch by overhead cable cranes done for first time o­n Indian Railways.
