The Howrah Bridge is a cantilever bridge that spans the Hooghly River in West Bengal, India. Commissioned in 1943, the bridge was originally named the New Howrah Bridge, because it links the city of Howrah to its twin city, Kolkata (Calcutta). On 14 June 1965 it was renamed Rabindra Setu, after Rabindranath Tagore a great Bengal poet and the first Indian Nobel laureate. However it is still popularly known as the Howrah Bridge.

The bridge is one of the four on the Hooghly River and is a famous symbol of Kolkata and West Bengal. The other bridges are the Vidyasagar Setu (popularly called the Second Hooghly Bridge), the Vivekananda Setu and the newly built Nivedita Setu. Apart from bearing the stormy weather of the Bay of Bengal region, it successfully bears the weight of a daily traffic of approximately 100,000 vehicles and possibly more than 150,000 pedestrians, easily making it the busiest cantilever bridge in the world. The third longest cantilever bridge at the time of its construction, it is currently the sixth longest bridge of its type in the world.
