Kalyani Expressway is a 40-kilometre-long (25 mi), two-laned, tolled road which connects Kolkata with its satellite town, Kalyani in Nadia district. The road starts from Nimta in the North 24 Parganas district, in the suburbs of Kolkata, and ends in Kalyani. The road is maintained and controlled by Kolkata Metropolitan Development Authority (KMDA). It has been planned to convert the two lane road into a four lane road by the KMDA.
The road acts as a bypass avoiding the congested roads along the towns and cities, like Sodepur, Barrackpore, Naihati, which developed along the Hooghly River. The road has significantly brought down the communication time between the cities from two hours to one hour.
