Overview of Kalyani Expressway

Originally constructed in the 1980s as the Kalyani-Barrackpore Expressway (35 km), the highway was extended by 9 km from Sodepur Road to Barasat in 2005. The KMDA now manages the highway, which runs from Kalyani to Nimta in the 24-Parganas (North) district. This stretch has recently been converted into a 4-lane motorway, while the section from Belgharia to Muragacha has been upgraded to 6 lanes.

The expressway provides a strategic bypass, allowing commuters to avoid congested towns like Sodepur, Barrackpore, and Naihati. It also intersects key feeder roads connecting Barrackpore, Barasat, Madhyamgram, Khardaha, and Kanchrapara, further facilitating seamless regional transit.
