Behind India’s Tallest Railway Arch, A Woman Scientist Who Made It Possible.jpeg)

When Prime Minister Narendra Modi inaugurated the Chenab Bridge in Jammu & Kashmir on Friday — the world’s tallest railway arch and a symbol of India’s engineering prowess — few knew of the quiet force behind this national milestone: Prof G Madhavi Latha, a rock engineering expert from the Indian Institute of Science (IISc), Bengaluru.
For nearly two decades, Prof Latha has worked behind the scenes, providing critical geotechnical expertise on one of India’s most complex and high-stakes infrastructure projects. Rising 359 metres above the riverbed, taller than the Eiffel Tower, and spanning 1,315 metres across the Himalayan terrain, the Chenab Bridge is now a vital rail link connecting the Kashmir Valley with the rest of India.
A Bridge Built on Science — and Resilience
The ₹1,486-crore Chenab Bridge was no ordinary construction. Located in a high seismic zone, with steep, unstable slopes and unpredictable rock formations, the project required more than just engineering — it needed real-time problem-solving in uncharted territory.
That’s where Prof Latha came in.
Recruited in 2005 by Northern Railways and project contractor Afcons Infrastructure Ltd, Prof Latha was brought on board as part of IISc’s long-term consultancy. Her responsibility: ensuring the stability of slopes, the design of deep rock foundations, and the use of rock anchors to secure the structure in some of the harshest geological conditions in India.
Speaking to Deccan Herald, Prof Latha explained the adaptive engineering approach they used:
“We had to constantly adapt, because the initial geological data didn’t match the reality of the rock conditions when we began excavation.”
The team used a rare “design-as-you-go” approach, modifying designs in real time as new geological data emerged. It was a process that tested scientific rigor, patience, and persistence.
Leading Through the Unknown
In the initial stages of the project, another IISc faculty member co-advised the construction team. But when he stepped away a few years later, Prof Latha carried the burden alone — all the way until the completion of the bridge’s structural phase in 2022 and the beginning of full-speed train trials.
Her work continued even as the public spotlight shone elsewhere — on political speeches, timelines, and cost estimates. But those who understand the Chenab Bridge’s technical depth say it wouldn’t have stood without her.
On social media, the Indian Institute of Science celebrated the milestone with a tribute:
“We are proud of Prof Madhavi Latha & her team's contribution to the #ChenabBridge,” the institute posted on X. “Their work on slope stability, rock anchors, and foundational design has been critical to withstanding geological hazards.”
The Bigger Picture: Women in Infrastructure
Prof Latha’s story is not just about science — it’s also about representation. In a field where women are still underrepresented, especially in on-site civil and rock engineering, her leadership sets a powerful example.
Her success highlights the expanding role of Indian women scientists in national infrastructure, defence, space research, and disaster resilience — areas long dominated by male counterparts.
In 2022, when the Chenab Bridge trials began, she quietly stepped back from public attention, as engineers took over final testing. But the imprint of her work — embedded in the rock itself — will remain for generations.
A Monument of Steel, But Also of Human Dedication
The Chenab Bridge is a marvel of steel and design, but it is also a monument to silent contributors like Prof Madhavi Latha, whose expertise turned an ambitious blueprint into India’s greatest railway feat.
Now fully operational, the bridge doesn’t just carry trains — it carries a message: that scientific leadership, especially by women, is no longer behind the scenes.
It is time we celebrate the minds that make modern India move forward — one rock at a time.
