2.5 hours to 45 minutes: How new signal-free Kalyani Expressway is transforming commuting in Kolkata
This expressway bypasses major bottlenecks like Barasat and Madhyamgram, providing a vital "green corridor" to AIIMS Kalyani and a direct link between the Belgharia Expressway and the northern industrial hub.

The gruelling two-and-a-half-hour commute between Kolkata and the industrial hub of Kalyani has officially come to an end. In a landmark infrastructure milestone for West Bengal, Chief Minister Mamata Banerjee inaugurated the upgraded 44.2-km Kalyani Expressway on March 2, transforming a notorious traffic bottleneck into a seamless, high-speed corridor.
What was once a slow crawl through the congested stretches of North 24 Parganas is now a swift 40 to 45-minute journey, offering a massive reprieve for daily commuters, commercial freight, and medical emergency vehicles.
Executed by the West Bengal Highway Development Corporation Ltd (WBHDCL) at an investment of Rs 2,500 crore, the 4/6-lane “super highway” is designed to completely bypass heavy urban congestion in areas like Barasat, Birati, and Madhyamgram.
Key infrastructure highlights
21 new flyovers: Spanning nearly 24 km, these structures ensure a signal-free experience.
Nimta-Belgharia link: A 1.5-km elevated connector that links the airport-bound Belgharia Expressway directly to the Kalyani corridor.
Medical ‘green corridor’: The route drastically slashes transit time to AIIMS Kalyani, providing life-saving access for patients travelling from the city.
Strategic connectivity: The highway integrates with State Highways 1 and 2 and provides a direct link to NH-12 via the Kapa-Barajaguli corridor.

Bypassing bottlenecks
For years, commercial vehicles heading toward North Bengal, the North-Eastern states, and Bangladesh were held up by the narrow, densely populated stretches of BT Road and Jessore Road. The new expressway offers a high-efficiency alternative, allowing freight to move without the traditional “stop-and-go” delays of suburban Kolkata.
Beyond transit, the corridor is acting as a catalyst for economic growth. Residential projects, industrial zones, and educational hubs—including Kalyani University—are seeing a surge in development as the distance between the satellite town and the capital effectively shrinks.
The project is being rolled out in two strategic phases, focusing on the stretch from Nimta to Muragacha and moving upward to Kampa.
Looking ahead, the expressway’s utility will expand even further with the completion of the second Ishwar Gupta Setu. This extradosed cable-stayed bridge over the Hooghly River will create a 6-lane link between the industrial centres of Hooghly and the Kalyani corridor, forming a comprehensive regional grid.

“This corridor is not just a road; it is a vital lifeline that streamlines access from the airport to the northern suburbs, ensuring that the region’s economy can finally move at ahigh speed,” said an official.
