India opens world's highest railway arch bridge built with 28,000 tonnes of steel
Indian Prime Minister Narendra Modi inaugurated the Chenab Railway Bridge, the World 's tallest railway arch bridge at 359m above the Chenab River, 35m taller than the Eiffel Tower, connecting Kashmir to the rest of India via rail. The 1,315m bridge, part of the Udhampur-Srinagar-Baramulla Rail Link (USBRL) project, was built with over 28,000 tonnes of Steel, designed to last 120 years, and can withstand high winds (up to 266kmph) and seismic activity (up to magnitude 8). Engineering challenges included stabilising slopes in the fractured Himalayan geology, with G Madhavi Latha from the Indian Institute of Science advising on slope stabilisation and foundation design, requiring real-time construction plan modifications based on geological data. Construction involved building 26km of new roads to transport heavy machinery to the remote site, with the USBRL project costing Rs437.8bn (£3.7bn) and the Chenab Bridge alone costing approximately Rs14.86bn (£128m). The Chenab Bridge, designed with contributions from Indian and international firms, including WSP Finland and Leonhardt Andrä und Partner, aims to significantly reduce travel time between Katra and Srinagar to three hours via the Vande Bharat Express.

The Chenab Bridge: The making of world's highest railway bridge that can weather an earthquake
Prime Minister Narendra Modi will inaugurate the Chenab Bridge, the world's highest railway bridge, in Jammu and Kashmir today. This structure, constructed for Rs 1,486 crore, is an engineering marvel; it's been built high up in the mountains — it's actually 35 metres taller than the Eiffel Tower and designed to withstand a powerful earthquake or a 40 kg-TNT blast read more Chenab Rail Bridge, world's highest railway bridge, over the Chenab river in Reasi district. It is part of Indian railways' Udhampur-Srinagar-Baramulla Railway Link (USBRL) project. PTI It's been called an engineering marvel, a man-made wonder, a symbol of naya Kashmir. But the many adjectives still fail to capture the masterpiece that is the Chenab Bridge in Jammu and Kashmir, which will be inaugurated by Prime Minister Narendra Modi on June 6. The world's highest railway arch bridge, located in the Reasi district of Jammu and Kashmir, is part of the Udhampur-Srinagar-Baramulla rail link project (USBRL), that aims to boost connectivity in Jammu and Kashmir. STORY CONTINUES BELOW THIS AD Ahead of the big day, we take a closer look at how the Chenab Bridge is indeed a remarkable feat of engineering and how it's been designed to withstand earthquakes and a whopping 40 kg-TNT blast. Designed in Finland, executed in India The Chenab Bridge, touted to be the world's highest railway bridge, has been designed by WSP Finland with German firm Leonhardt, Andrä und Partner designing the bridge arches, and Vienna Consulting Engineers aiding in the design of the pylons. Once designed, the workers and engineers of Konkan Railway Corporation brought the plans to life. History in the making! The Chenab Bridge—the world's highest railway arch bridge—is now a reality! Spanning the Chenab River in J&K, it symbolizes India's infrastructural excellence. Prime Minister @narendramodi is all set to inaugurate the world's highest railway bridge — the… — DD News (@DDNewslive) June 4, 2025 And it has been no easy feat. Measuring 1,315 metres long, it is built over the Chenab river in the Kouri region of the Reasi district. What makes the bridge truly astounding is the fact that it stands high at 359 metres (1,178 feet) above the Chenab riverbed, making it the world's highest railway bridge. For those who want perspective — 359 metres is about 35 metres taller than the Eiffel Tower in Paris. The bridge construction involved 28,660 metric tonne of steel, 10 lakh cubic metre earthwork, 66,000 metre of concrete and 26 km of motorable roads. According to those involved in the building of the Chenab Bridge, the overall weight of the arch is a whopping 10,619 metric tonnes. The construction of this bridge has been an expensive affair too; it's taken Rs 1,456 crores and at its peak a whopping 3,200 workers and engineers working simultaneously. STORY CONTINUES BELOW THIS AD Once inaguruated and open to use, the Chenab Bridge will see trains being able to travel at speeds of up to 100 kmph on the bridge, with all necessary safety measures in place to ensure smooth and secure travel. The Chenab Bridge stands high at 359 metres (1,178 feet) above the Chenab riverbed, making it the world's highest railway bridge. Image Courtesy: DD News/X Chenab Bridge built to sustain quakes and explosions The Chenab Bridge isn't just beautiful to look at. It's also the culmination of the best engineering minds in the country. Realising that the bridge will be built high up in the seismically active mountains, experts from Indian Institute of Technology, Roorkee studied the rock slopes and then suggested ways to ensure that the construction wouldn't collapse in case of a quake. For instance, they stabilised the slopes using used three techniques: grouting, anchor blocking, and shotcrete. Moreover, the Chenab Bridge's rail deck is isolated from its substructure using spherical bearings. It is this isolation that the rail deck and the train experience minimal impact from the earthquake. All of these steps taken during construction now ensures that the bridge can withstand an earthquake measuring a whopping eight on the Richter scale. Additionally, it can withstand high wind speeds of up to 266 km/hour. STORY CONTINUES BELOW THIS AD The Chenab Bridge has been built with 63 mm-thick special blast-proof steel. Image Courtesy: Speaking on the sturdiness of bridge, Chief Engineer (Coordination) R K Hegde of Konkan Railways told news agency PTI, 'It can withstand high-intensity blasts of up to 40 kg of TNT and an earthquake. Even after the blast, a train can run at a speed on 30 kmh.' Explaining further, he said that the bridge has been built with 63 mm-thick special blast-proof steel owing to Jammu and Kashmir's tendency to witness multiple terror attacks. He added, 'It is for the first time that self-compacting concrete is being used for filling steel boxes and ends of plate girders.' Design firm WSP has also used Tekla software in the construction of the Chenab Bridge. Tekla structures is a software used in the construction industry, primarily for structural engineering and detailing, particularly for steel and concrete structures. It allows professionals to create, manage, and share 3D models, from conceptual design to fabrication, promoting accuracy and efficiency. STORY CONTINUES BELOW THIS AD People involved in the construction note that the bridge's life is estimated to be 120 years. To ensure its longevity, corrosion-resistant paint has been used. Moreover, it has been equipped with an online safety monitoring system for real-time alerts. The Chenab Bridge construction involves 28,660 metric tonnes of steel, 10 lakh cubic metre earthwork, 66,000 metre of concrete. Image Courtesy: Ministry of Railways/X A bridge many years in the making The inauguration of the Chenab Bridge by PM Modi comes several years after the project was initially announced. Construction on the bridge began in 2004 but alignment and safety concerns delayed progress. Work resumed after design adjustments in 2010. The deck was joined to the steel arch in April 2021, followed by the deck joining in August 2022. In June last year, the Indian Railways carried out a successful trial run of an eight-coach Mainline Electric Multiple Unit (MEMU) train on the famed Chenab Bridge. The trial on June 21, began at 12.35 pm from Sangaldan and reached Reasi at 2.05 pm, traversing nine tunnels spanning 40.787 km, including the longest tunnel T-44 stretching 11.13 km.
