Vidyasagar Setu, also known as the Second Hooghly Bridge, is a toll bridge over the Hooghly River in West Bengal, India, linking the cities of Kolkata and Howrah.

The Hooghly River or popularly called Ganga or Kati-Ganga in the Puranas, is a river that rises close to Giria, which lies north of Baharampur and Palashi in Murshidabad. It is the western distributary of the Ganges. The main course of the Ganges then flows into Bangladesh as the Padma. A man-made canal, built in the 1960s and early-1970s at Farakka, connects the Ganges, flowing through Malda, to the Hooghly to bring the abundant waters of the Himalayan river to the comparatively narrow river that rises in eastern West Bengal.
