FAQs On Vidyasagar Setu

Kolkata, West Bengal, India

Vidyasagar Setu, popularly known as the Second Hooghly Bridge, is a monumental cable-stayed bridge that links the twin cities of Kolkata and Howrah. Named after the legendary 19th-century social reformer and polymath Pandit Ishwar Chandra Vidyasagar, it is one of the longest bridges of its kind in

FAQs on Vidyasagar Setu

Ans:- During its design phase, the bridge was subjected to extensive prototype wind tunnel tests at the Indian Institute of Science (IISc) in Bangalore. These tests ensured that the cable-stayed structure could withstand the high-velocity winds and cyclonic conditions often experienced in the Bay of Bengal region. The steel pylons and the dead-load composite deck are engineered to maintain stability even during severe weather, ensuring the safety of thousands of commuters.

Ans:- It is called the Second Hooghly Bridge because it was the second major bridge built across the Hooghly River in the Kolkata metropolitan area, following the iconic Howrah Bridge (Rabindra Setu). While the Howrah Bridge connects central Kolkata to Howrah Station, Vidyasagar Setu provides a vital link between the southern parts of Kolkata and the Kona Expressway, helping to significantly reduce traffic congestion.

Ans:- The bridge connects the twin cities of Kolkata and Howrah. On the Kolkata side, it links to the area near Prinsep Ghat and Hastings, while on the Howrah side, it connects directly to the Kona Expressway. This connection is vital for travelers heading toward Mumbai or Delhi via National Highway 16, as it bypasses the more congested city centers and provides a direct route to the suburbs.

Ans:- The bridge was designed by the renowned German firm Schlaich Bergermann & Partner. The technical aspects and construction were checked and supervised by Freeman Fox & Partners and Bharat Bhari Udyog Nigam Limited. The actual construction was carried out by a consortium led by Braithwaite, Burn & Jessop (BBJ). This international collaboration ensured that the bridge met global standards for cable-stayed structures and wind resistance.

Ans:- The bridge was designed to handle a capacity of approximately 85,000 vehicles per day. It features six lanes of traffic (three in each direction), allowing for a smooth flow of heavy vehicles, buses, and private cars. This high capacity was essential to alleviate the extreme pressure on the older Howrah Bridge, which had previously been the primary artery for all traffic crossing the river.

Ans:- The construction of Vidyasagar Setu took over 20 years to complete, with the foundation stone laid by Prime Minister Indira Gandhi in 1972. The bridge was finally commissioned and opened to traffic on October 10, 1992. Despite the long construction period, it was a landmark achievement for the Hooghly River Bridge Commissioners (HRBC) and the various engineering firms involved in its design and execution.

Ans:- The historic Prinsep Ghat is located right at the base of Vidyasagar Setu on the Kolkata bank. This 19th-century monument, with its Greek-style columns, provides a sharp architectural contrast to the modern engineering of the bridge. The area around Prinsep Ghat is a popular recreational spot with landscaped gardens, food stalls, and boating facilities, making it the best place for tourists to admire the bridge.

Ans:- The total cost of constructing Vidyasagar Setu was approximately ₹3.88 billion (388 crore rupees). At the time of its completion in 1992, this was a massive investment for the state and central governments. When adjusted for inflation today, the cost would be significantly higher, reflecting the scale of the materials used, including 13,200 tonnes of structural steel and specialized high-tensile cables imported for the project.

Ans:- Vidyasagar Setu, also known as the Second Hooghly Bridge, is a cable-stayed bridge with a total length of 823 meters (approximately 2,700 feet). It was the first bridge of its kind in India and remains one of the longest cable-stayed bridges in Asia. The bridge features a main span of 457.2 meters and is supported by 121 cables in a fan arrangement, showcasing remarkable structural engineering.

Ans:- While there are narrow footpaths on both sides, walking across the entire bridge can be quite strenuous due to its length and the high speed of passing traffic. Most tourists prefer to take photographs from Prinsep Ghat, which is located directly beneath the bridge on the Kolkata side. The view from the ghat offers a spectacular perspective of the bridge’s cables and pylons, especially during sunset and when it is illuminated at night.

Ans:- Yes, there is a vertical clearance of approximately 26 meters (about 85 feet) below the bridge during high tide. This clearance allows most medium-sized vessels and river cruises to pass safely. This was a critical design requirement, as the Hooghly River is an active waterway for commercial shipping and the Kolkata Port Trust operations, necessitating that the bridge does not obstruct the flow of maritime traffic.

Ans:- Yes, Vidyasagar Setu is a toll bridge for motorized vehicles. There are toll plazas located on the Howrah side of the bridge. However, in a unique move to promote eco-friendly transport, the bridge features dedicated lanes for bicycles, and cyclists are allowed to cross free of charge. Pedestrians can also use the narrow footpaths on either side of the bridge to enjoy the view.
