India Railways complete the Arch closure of iconic Chenab Bridge the world's highest Railway Bridge

Chenab Bridge, the world's highest railway bridge, part of the Udhampur-Srinagar-Baramulla rail link project (USBRL), set an important construction milestone with the completion of the steel arch of the iconic Chenab Bridge.


India Railways complete the Arch closure of iconic Chenab Bridge the world's highest Railway Bridge

April 6, Delhi: One of the most difficult parts 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 and joined the 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 Piyush Goyal Minister for Railways, Commerce & Industry and Consumer Affairs, Food & Public Distribution, Suneet Sharma, Chairman & CEO, Railway Board, Ashutosh Gangal, General Manager Northern Railway through video conferencing.


Salient Features of the Arch of the iconic Chenab Bridge:

  • Indian Railways is constructing the iconic Arch Bridge on River Chenab as a part of the USBRL project to connect the Kashmir valley to the rest of the nation.

  • 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.

  • The arch consists of steel boxes. Concrete will be filled in boxes of the Arch to improve stability.

  • The overall weight of Arch is 10,619 MT.

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

  • The most sophisticated ‘Tekla’ software used for structural detailing.

  • Structural steel is suitable for -10°C to 40°C temperature.



Unique Features of This Bridge:

  • Bridge designed to withstand high wind speed up to 266 Km/Hour.

  • Bridge designed for blast load in consultation with DRDO for the first time in India.

  • The bridge will remain operational at a restricted speed of 30 Km/Hour even after the removal of one pier/trestle.

  • Bridge designed to bear earthquake forces of highest intensity zone-V in India.

  • First time on Indian Railways, a Phased Array Ultrasonic Testing machine used for testing welds.

  • First time on Indian Railways, NABL accredited lab established at the site for weld testing.

  • Approx. 584Km welding done to join the different parts of the structure, which is to the tune of the distance between Jammu Tawi to New Delhi.

  • The height of the cable crane’s pylon at Srinagar End is 127m, which is much taller than Qutub Minar of 72m.

  • Launching of curved viaduct portion done for the first time on Indian Railways using End Launching Method.

  • Extensive health monitoring and warning systems planned through state of art instrumentation.

Details about the ceremony of Arch Closure:

  • Before closure and during launching, the arch is being supported by stay cables.

  • The closure includes the erection of the last 8 segments (4 no. upstream and 4 no. downstream) of Arch.

  • The process of arch closure started on 20 February 2021. Before the ceremony for the closure of the arch, 07 segments were erected in advance.

  • At the time of closure of arch, segment no. WT28 was erected. This segment is at the kauri end (west end) of the crown.

  • Name: WT28 (upstream side top chord segment)

  • Size: 5.6 m x 4.0 m x 0.98 m ( L x B x H ); Weight =18.95 MT

After the closure of the Arch, other activities such as removal of stay cables, filling of the concrete arch with self-compacting concrete, erection of trestles, launching of the deck over the main arch by incremental launching will be undertaken.
