• Total length: about 1,315 metres.
• Main arch span: about 467 metres.
• It is built of steel and designed to withstand high winds of up to about 260 km per hour and strong earthquakes.
• It has a design life of about 120 years.
• It was built by Indian Railways, through Konkan Railway Corporation and Afcons Infrastructure, with international consultants.
• Prime Minister Narendra Modi inaugurated it on 6 June 2025, along with the full Udhampur-Srinagar-Baramulla Rail Link (USBRL).

The USBRL project:

• The 272 km long Udhampur-Srinagar-Baramulla Rail Link connects the Kashmir Valley with the rest of India's railway network.
• It includes many tunnels and bridges; the Pir Panjal tunnel (about 11 km) and the T-50 tunnel (about 12.8 km, India's longest transport tunnel) are part of it.
• Vande Bharat trains now run between Katra and Srinagar.
• The Anji Khad Bridge, India's first cable-stayed railway bridge, is also part of this line.

About the Chenab river:

• It is formed by the confluence of the Chandra and Bhaga rivers at Tandi in the Lahaul-Spiti district of Himachal Pradesh, where it is called the Chandrabhaga.
• It flows through Himachal Pradesh and Jammu and Kashmir, cutting deep gorges, and enters Pakistan near Akhnoor.
• It is one of the western rivers of the Indus system whose waters were allotted mainly to Pakistan under the Indus Waters Treaty.
• Projects such as Salal, Baglihar, Dulhasti and Ratle are built or being built on it.
