More than Steel and Cables : Zuari Bridge showcased as a Monument of India’s Engineering precision

Goa Khabar : There is magic and charm around Goa’s latest infrastructural landmark, the new but already iconic Zuari Bridge, according to veteran bridge engineer Utpal Chakravarty, who led the construction of the Zuari Cable-Stayed bridge, who was speaking at a recent MOG Sunday talk at the Museum of Goa in Pilerne. 

According to Chakravarty, the landmark bridge serves as a symbol of aspiration for the people in the region and the construction of a viewing tower atop the structure, which is being aggressively pursued by Union Minister for Road Transport and Highways Nitin Gadkari and the Goa government, would make the iconic bridge an even bigger landmark.

“Once you create a particular structure (like the Zuari bridge), people aspire to do something bigger, something better. (Such things) can take you to the next level,” Chakravarty said, about the cable-stayed bridge that is now celebrated as one of India’s most complex and visually striking infrastructure achievements. Spanning the Zuari River and connecting North and South Goa, the bridge represents not just connectivity but the sheer scale of modern Indian engineering ambition.

Chakravarty walked through the construction stages with photographs documenting every phase — from submerged foundations to towering pylons and cable installations conducted hundreds of feet above water. He highlighted that the entire 360-metre central span was built without any supporting pillar beneath, resting entirely on tensile strength and precision balancing. “Every time a new segment was lifted and connected, we had to recheck stress levels and correct balance before adding the next one,” he said, explaining how cantilever forces constantly pulled each side downward.

The bridge’s safety systems were equally rigorous, Chakravarty said. A total of 106 segments — each weighing nearly 100 tons — were assembled and stitched with concrete, with hydraulic jacks used to make micro-adjustments. Cable load testing was conducted across facilities in China and the US, as India currently lacks the infrastructure for full-scale stress simulation. “We test cables to 95 percent of their ultimate strength, but in real-world design we are allowed to use only 45 percent,” Chakravarty noted. “Even if one cable fails, the structure will stand — the load will simply shift to the next.”

Recalling the wind tunnel experiments conducted at CSIR-SERC in Chennai, he shared how initial designs were modified after simulations showed that solid crash barriers would trap wind pressure. “We replaced concrete barriers with steel so air could pass through — sometimes design must bow to physics,” he remarked.

The bridge’s final validation came through a dramatic live load test with 32 trucks positioned across the deck. Engineers observed not just how far the structure bent — but how perfectly it returned to position.

Beyond technical mastery, the bridge is expected to reshape Goa’s economy and tourism. With an observatory tower under consideration and improved connectivity for local villages, the bridge is projected to increase footfall, stimulate local businesses, and enhance overall accessibility across the state.

“As of now, it is only the bridge. Once the tower comes, it will become even more, a bigger landmark, you know,” he said. The Eiffel Tower–inspired observatory towers atop the bridge, a viewing gallery, a revolving restaurant and an art space are expected to offer panoramic views of Goa and are being pitched as a global tourist attraction.

The Zuari Bridge is today the second-longest cable-stayed bridge in India at the time of its completion and a testament to visionary planning, engineering skill, and resilience. Chakravarty, who has documented the bridge’s construction through photography, reflects, “For me, this project was eye-opening, offering insight into large-scale structures and the global standards we aspire to achieve. It’s more than a bridge—it’s a landmark for Goa and a milestone for India’s infrastructural journey.”
