The Vidyasagar Setu, commonly known as the Second Hooghly Bridge, is a significant engineering marvel in Kolkata, West Bengal. Here are additional details about this iconic structure:
The bridge spans a total length of 1,500 meters (4,921 feet), making it one of the longest cable-stayed bridges in India. It is constructed primarily of steel and reinforced concrete, providing both strength and durability.
The bridge is supported by 152 cables that are sheathed in high-density plastic to protect against environmental factors and wear. These cables are anchored to two towering pylons, each rising to a height of 127 meters (417 feet), which hold the entire structure.
Work on Vidyasagar Setu commenced in 1977 and took 15 years to complete. The bridge was officially opened for public use in 1992, symbolizing modern engineering and urban development in Kolkata.
The construction involved extensive planning and use of advanced engineering techniques. It was designed to alleviate traffic congestion on the older Howrah Bridge and improve connectivity between Kolkata and Howrah across the Hooghly River.
The bridge is a vital transportation link, accommodating vehicular traffic, pedestrians, and even bicycle traffic. It connects the bustling city of Kolkata with the industrial and suburban areas of Howrah, facilitating smoother transit.
Vidyasagar Setu plays a crucial role in the economic activities of the region by improving access to important commercial hubs, markets, and ports, thus boosting trade and commerce.
The bridge’s design incorporates a sleek and modern aesthetic, with its cable-stayed structure offering a visually appealing silhouette against the skyline of Kolkata. It is especially striking when illuminated at night, becoming a prominent landmark.
The bridge is named in honor of Ishwar Chandra Vidyasagar, a prominent social reformer, educator, and advocate for women’s rights in India. This reflects the cultural and historical significance attached to the structure.
Given its importance and heavy usage, Vidyasagar Setu undergoes regular maintenance to ensure its structural integrity and safety. This includes inspections of the cables, deck, and support systems.
Beyond its functional role, Vidyasagar Setu has become a cultural icon of Kolkata. It is often featured in films, literature, and artwork, symbolizing the city’s blend of tradition and modernity.
The bridge and its surrounding areas have become popular spots for locals and tourists alike, offering panoramic views of the Hooghly River and the cityscape.
The Vidyasagar Setu is not just a critical infrastructure project but also a symbol of Kolkata’s progress and resilience. Its impressive design, engineering excellence, and strategic importance make it a cornerstone of the city’s transportation network and a cherished cultural landmark.
