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 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 Mr. Piyush Goyal Minister for Railways, Commerce & Industry and Consumer Affairs, Food & Public Distribution, Mr. Suneet Sharma, Chairman & CEO, Railway Board, Mr. Ashutosh Gangal, General Manager Northern Railway through video conferencing.
