Bidhan Sarani (formerly known as Cornwallis Street) is a principal North-South thoroughfare in north Kolkata, the capital of the Indian state of West Bengal. It was named after the first Chief Minister of West Bengal, Bidhan Chandra Roy. As the continuation of College Street the road starts from Keshab Chandra Sen Street in the south and extends till Galiff Street iin the north, after which the street continues as Barrackpore Trunk Road. Bidhan Sarani encompasses the neighbourhoods of Shyambazar, Hatibagan, Hedua, Shimla, Thanthania and College Street.
The three-mile long Maratha Ditch was excavated in 1742 as a protection against the marauding Maratha soldiers then foraging in the countryside but who never came. It was filled up in 1799 to build the Circular Road, that ran from Shyambazar, right around old Kolkata, covering the southern end of the Maidan. It was metalled in the early 19th century. Around the same time, the most important axial thoroughfare from south to north — Wood Street (portion renamed Dr. Martin Luther King Sarani), Wellesley Street (renamed Rafi Ahmed Kidwai Street), Wellington Street (renamed Nirmal Chandra Street), College Street and Cornwallis Street (renamed Bidhan Sarani) — was built by the Lottery Committee.
The Hatibagan Bazar is located on Bidhan Street. A street market along Bidhan Sarani, which continues till Aurobindo Sarani crossing has resulted in congestion of the area.
The Star Theatre located on Bidhan Sarani was famous for over 100 years and during the period nearly 250 Bengali dramas of more than 80 playwrights were performed by different producers. More than 12 Hindi dramas were also staged at the Theatre. Unfortunately a fire destroyed the glorious Star Theatre on 16 October 1991. It has again been built but it has failed to regain its old glory. With six cinema halls — Radha, Rupbani, Minar, Mitra and Darpana — in a row along Bidhan Sarani the road was considered to be the entertainment hub in the city.
The Bethune College, is situated on Bidhan Sarani near Hedua. The street is also famous for sweetmeat shops like Girish Chandra Dey & Nakur Chandra Nandy.
