In a world chasing technological innovation, the Chenab Bridge demonstrates a deep understanding of materials, terrain, and structural engineering.

When Prime Minister Narendra Modi inaugurated the Chenab Bridge in Jammu and Kashmir on June 6, 2025, it was more than just another landmark infrastructure project added to extend the reach of the Indian Railways.

The Chenab Bridge, the world's highest railway bridge, holds significant strategic, infrastructural, and economic importance for India, particularly for the Jammu and Kashmir region. Its construction connects the Kashmir Valley to the Indian railway network, enhancing connectivity, facilitating trade, and bolstering tourism. The bridge is also seen as a symbol of India's engineering capabilities and its resolve to overcome challenging terrains

Spanning the mighty Chenab River in the challenging terrain of Jammu & Kashmir, the Chenab Bridge stands not only as the world’s highest railway bridge but also as a testament to India's engineering prowess. At a height of 359 metres (1,178 feet) above the riverbed – 35 metres higher than the Eiffel Tower – the bridge is a key part of the Udhampur-Srinagar-Baramulla Rail Link (USBRL) project, intended to connect the Kashmir Valley with the rest of India via rail.

The most striking aspect of this engineering marvel is its arch design, reminiscent of classic bridges but executed with modern finesse. The bridge has a central steel arch that spans 467 metres, making it the longest span for a railway arch bridge in the world. The total length of the bridge is 1,315 metres, comprising a combination of viaducts and approach spans. Its arch design allows it to absorb and distribute wind pressure and seismic activity more efficiently – crucial in a zone that is both geologically sensitive and exposed to extreme winds.

One of the most defining features of the Chenab Bridge is the use of specially engineered steel, designed to withstand the harshest climatic and environmental conditions. The bridge is constructed using austenitic steel and weather-resistant steel, capable of tolerating temperatures as low as -20°C and wind speeds up to 266 km/h. The grade of steel used is E250 and E410 (copper bearing), ensuring high tensile strength and resistance to corrosion – a must in a region with snowfall, rainfall, and temperature extremes.

A total of around 30,000 metric tonnes of steel were used in the construction, much of it fabricated in workshop conditions before being assembled on-site using precision techniques like incremental launching and advanced welding. The steel arch itself was erected using cable crane and derrick arrangements across the deep gorge – making it one of the most challenging bridge erection operations in modern engineering.

To ensure long-term integrity, the bridge employs structural health monitoring systems, including 100+ sensors to track wind pressure, seismic activity, temperature fluctuations, and structural stress. Additionally, the bridge is designed to have a service life of 120 years, underlining the precision and foresight in its engineering.

Built by Konkan Railway Corporation Ltd, with Afcons and DRDO providing engineering and safety expertise, the Chenab Bridge is not just a civil engineering feat – it is also a symbol of connectivity, perseverance, and progress in one of India’s most remote regions. Its successful completion paves the way for all-weather rail access to the Kashmir Valley, dramatically improving strategic and socio-economic connectivity.

In a world chasing technological innovation, the Chenab Bridge shows how a deep understanding of materials, terrain, and structural engineering can come together to create something enduring and extraordinary.
