Bidhannagar

History

During the Salt Satyagraha, the people of Mahishbathan between present day Salt Lake and Rajarhat Newtown joined the Salt Satyagraha movement by preparing salt using indigenous methods. The main initiator of the movement was Lakshmikant Pramanik, the zamindar of Mahishbathan.

Bidhannagar's master planner and chief architect was Dobrivoje Tošković.

Bidhannagar's architecture has modern landmarks, such as the Vivekananda Yuba Bharati Krirangan or Salt Lake Stadium.

Doma Wang began working as a chef in Bidhannagar.

Background

On 23 January 1948, Bidhan Chandra Roy was sworn in as the second Chief Minister of West Bengal. The most pressing problem he faced was the mass influx of refugees crossing the border from East Pakistan, which caused Calcutta's population to grow rapidly. This overcrowding led Roy to conceive a reclamation project on the marshy salt lakes to the east of the city, with the aim of relieving population pressure on Kolkata.

Reclamation and construction

The landfill project was inaugurated on 16 April 1962 by Roy, accompanied by Irrigation Minister Ajay Mukherjee and Parliamentary Affairs Minister Jagannath Kole. Roy died less than three months later, on 1 July 1962.

Reclamation of Sector I was completed in 1965, and plot distribution in that sector began the following year. Sectors II and III were reclaimed by 1969. The first residents of the township, Jitendranath Chakraborty and his family, moved into house AB 129 in Sector I on 9 March 1970. Plot distribution for Sector II began in 1979, and for Sector III in 1980.

Renaming

On 5 April 1973, a circular published in the Calcutta Gazette officially changed the name of Salt Lake City to "Bidhannagar", in honour of Bidhan Chandra Roy.

Geography

Salt Lake is located in the southeastern part of West Bengal. The city area sits within the lower Ganges Delta of eastern India. The Salt Lake area of Kolkata city was formed by land reclamation, which was done in the 1950s and 1960s to accommodate the growing population. Salt Lake is located on the north eastern area of Kolkata, the state capital; 65.2 kilometres (40.5 mi) west of Ghojadanga, a border checkpoint; and 128 kilometres (80 mi) north of Bakkhali.

According to the Bidhannagar Municipal Corporation, the city area has a total area of 55.51 square kilometres (21.43 sq mi), with approximately 30.51 square kilometres (11.78 sq mi) of it being land, and approx 25 square kilometres (9.7 sq mi), or 45.5% of the total, being covered by water. It has an average elevation of 11 metres (49 ft).

East Kolkata Wetlands, located within the city limits of Bidhannagar, lies across the southern part of the city. It is one of the two Ramsar sites in West Bengal, the other being the Sundarban Wetland.

Economy

Salt Lake Sector V is the largest information technology hub in Eastern India and ranks among the top ten information technology hubs in India. Colloquially referred to as the "Silicon Valley of the East", the area serves as the primary technology corridor of Kolkata, functioning as a peripheral business district governed by the Nabadiganta Industrial Township Authority (NDITA).

The sector is home to the Salt Lake Electronics Complex (SALTLEC), established in 1989 by Webel and spread across approximately 150 acres (61 ha). It became the first software technology park in the Kolkata metropolitan area. By 1999, the complex housed 160 companies across 135 acres; by 2006, this had grown to more than 170 IT/ITeS, biotechnology, and pharmaceutical companies. As of 2019, SALTLEC encompassed 63 electronic units and more than 200 IT/ITeS firms alongside numerous MSME companies.

The hub hosts the regional and national offices of several multinational corporations and Indian technology conglomerates. Tata Consultancy Services (TCS) operates major development centres managing software delivery, digital projects, and enterprise solutions. Wipro Limited maintains a dedicated Special Economic Zone campus of approximately 10 lakh sq. ft. across 20 acres in Sector V, with its Kolkata operations spanning 1.7 lakh sq. ft. and accommodating approximately 3,000 employees. Cognizant occupies approximately 2,50,000 sq. ft. at the Infospace campus, also accommodating over 3,000 employees.Other prominent occupants include Tech Mahindra, SAP SE, Ernst & Young, KPMG, PwC, Cisco, and Infosys. Collectively, IT and ITeS companies in Kolkata employ over 260,000 professionals, with Sector V serving as the primary employment centre.

Notable technology parks within the sector include Godrej Waterside (18 lakh sq. ft., established 2016), Godrej Genesis (15 lakh sq. ft., established 2014), the Wipro SEZ (10 lakh sq. ft.), Bengal Eco Intelligent Park, Infinity Think Tank, Infinity Adventz, and the Webel IT Park located at BN Block. The sector encompasses approximately 14.6 million square feet of total office space with ongoing expansions to accommodate rising demand.

Sector V benefits from strong transport connectivity, including a dedicated station on the Kolkata Metro East–West Metro line at Salt Lake Sector V metro station, direct access to the Eastern Metropolitan Bypass, and proximity to Netaji Subhas Chandra Bose International Airport. Beyond information technology, the hub supports industries including biotechnology, pharmaceuticals, and manufacturing, contributing to West Bengal's broader economic development. Adjacent to Sector V, Webel is further developing the Bengal Silicon Valley Tech Hub in New Town, aimed at attracting additional IT and telecom investments to the region.

By means of the borough committees, the corporation undertakes urban planning and maintains roads, government-aided schools, hospitals, and municipal markets. The functions of the KMC include water supply, drainage and sewerage, sanitation, solid waste management, street lighting, and building regulation.
