Madhavi Latha: The Engineer Behind the World’s Highest Rail Bridge
SCIENCE Madhavi Latha: The Engineer Behind the World’s Highest Rail Bridge When the Chenab Rail Bridge, the world’s highest railway bridge, stands tall amid the rugged Himalayas, it represents more than an engineering marvel. It tells the story of Dr. G. Madhavi Latha, the engineer whose expertise and vision played a pivotal role in turning an impossible idea into reality. She has also been awarded the NDTV Science Icon of the Year Award. Towering at 359 metres above the Chenab River in Jammu and Kashmir, the bridge is higher than the Eiffel Tower and is one of India’s most ambitious infrastructure projects. Designed to withstand extreme winds, earthquakes, and challenging geological conditions, the Chenab Bridge is a symbol of modern India’s engineering strength, and Dr. Madhavi Latha was at the heart of it. A professor at IIT Madras, Dr. Madhavi Latha, served as the geotechnical consultant for the project. Her role was crucial: the bridge stands in a highly seismic zone with fragile rock formations and unpredictable terrain. Traditional construction methods were not enough. Innovative geotechnical solutions were required to stabilise slopes, design foundations, and ensure long-term safety in one of the most hostile environments imaginable. Dr. Latha and her team worked extensively on slope stabilisation, foundation design, and rock reinforcement, addressing landslide risks and geological uncertainties. What made the challenge even greater was the remoteness of the site, harsh weather conditions, and limited accessibility. Despite these obstacles, her scientific approach and practical problem-solving ensured that the bridge could safely support high-speed trains while enduring nature’s extremes. Beyond its technical brilliance, Dr. Madhavi Latha’s contribution carries deep symbolic value. In a field traditionally dominated by men, her leadership and expertise have made her an inspiration for young engineers across India. She has often spoken about how the project demanded patience, collaboration, and unwavering commitment, qualities as critical as technical knowledge. The Chenab Rail Bridge is a vital link in the Udhampur–Srinagar–Baramulla Rail Line (USBRL) project, aimed at improving connectivity, mobility, and development in Jammu and Kashmir. Its completion marks a major milestone in India’s infrastructure journey. Dr. Madhavi Latha’s story reminds us that behind every iconic structure lies human effort, intellect, and resilience. As trains begin to cross the world’s highest rail bridge, they carry with them not just passengers, but the legacy of an engineer who redefined what was possible.

India’s DHRUV64: The First 1 GHz, 64-Bit Dual-Core Microprocessor
TECH India’s DHRUV64: The First 1 GHz, 64-Bit Dual-Core Microprocessor In a landmark moment for India’s semiconductor ambitions, the Centre for Development of Advanced Computing (C-DAC) has unveiled DHRUV64, the country’s first 1 GHz, 64-bit dual-core microprocessor. Developed under the government’s Microprocessor Development Programme and showcased as part of the Digital India RISC-V (DIR-V) initiative, DHRUV64 represents a major stride toward self-reliance in advanced chip design and computing technology. A Milestone in Indigenous Chip Design DHRUV64 is built on an open-source RISC-V architecture, an increasingly popular set of instructions that allows chip designers to innovate without costly licensing fees from foreign companies. Operating at a clock speed of 1.0 GHz with dual processing cores and 64-bit capability, it brings India into the realm of gigahertz-class embedded processors, a class previously dominated by global players. Unlike earlier academic or specialised chips, DHRUV64 is designed for broader strategic and commercial applications, including industrial automation, automotive electronics, 5G infrastructure, consumer devices, and Internet of Things (IoT) systems. It supports modern operating systems, integrates with diverse hardware systems, and provides multitasking efficiency suited for a range of real-world deployments. How Does It Matter? India currently consumes roughly 20 percent of the world’s microprocessors, yet historically has relied heavily on imports for core computing technology. Developing a homegrown processor like DHRUV64 is significant not only for technological sovereignty but also for enhancing security, reducing supply-chain vulnerabilities, and building local expertise in semiconductor design. By creating a platform that domestic startups, researchers, and established companies can build upon, DHRUV64 is expected to boost innovation across the electronics ecosystem and support cheaper prototyping and product development. It also provides a foundation for a growing pipeline of skilled chip design professionals, further energising India’s tech sector. A Step Toward Aatmanirbhar Bharat in Technology DHRUV64 marks a continuation of India’s journey toward an Aatmanirbhar (self-reliant) semiconductor ecosystem. The chip follows earlier indigenous designs such as SHAKTI, AJIT, VIKRAM, and THEJAS64, and sits alongside future variants like Dhanush and Dhanush+ in the development pipeline. While India still relies on global fabrication technologies for manufacturing, the design and strategic deployment of processors like DHRUV64 signal a slow but steady shift toward autonomous capabilities in core computing technologies, a critical competitiveness marker in the global tech landscape.
