The West Bengal government has given in-principle approval to transfer seven stretches of national highways to central agencies, clearing a months-long stalemate over pending infrastructure work. With the decision, responsibility for major routes such as NH-31, NH-33 and NH-312 will move to the National Highways Authority of India, while projects including the Sevok–Coronation Bridge stretch, Hasimara–Jaigaon route and Changrabandha corridor will be handled by the National Highways & Infrastructure Development Corporation Limited.
These projects had reportedly been awaiting the state’s approval for nearly a year. Following clearance from Nabanna, Central agencies are now set to begin work, with faster execution expected across North Bengal. The Chief Secretary has issued the formal directive.
Improving connectivity in North Bengal and border regions
As per a News18 report, the move is expected to strengthen road connectivity in the Darjeeling hills, Dooars and adjoining border areas. Officials say better highways will ease travel and improve links with neighbouring countries such as Bangladesh and Bhutan, which are crucial for trade and movement.

The state government maintains that handing over these stretches will help complete projects more efficiently and boost regional infrastructure, especially in areas that often face logistical challenges.
BIG boost for Northeast security & connectivity 🇮🇳

Union Minister Ashwini Vaishnaw has announced an ambitious plan to build 40 km of underground railway tracks along the strategically vital Siliguri Corridor, often called the “Chicken’s Neck”.

Why the Chicken’s Neck is critical?
The “Chicken’s Neck,” officially known as the Siliguri Corridor, is a narrow strip of land around Siliguri that connects mainland India to the Northeast. At just about 20 to 22 kilometre at its narrowest, it remains one of the country’s most sensitive geographic zones.
Flanked by Nepal to the west, Bhutan to the north and Bangladesh to the south, the corridor serves as a vital lifeline. Any disruption here could cut off access to the northeastern states, impacting millions of people and key supply routes.

Rail expansion and security focus in the corridor
The highway transfer comes alongside a larger push to strengthen infrastructure in the corridor. The Centre plans to expand railway capacity by upgrading existing double tracks into a six-track network. As part of this plan, two tracks are expected to run underground along a 40-kilometre stretch between Teen Mile Haat and Rangapani, at a depth of around 20 to 24 metre.
Underground rail lines are seen as a way to protect critical transport networks from potential threats such as air strikes or drone attacks, while ensuring the uninterrupted movement of goods and personnel.
Improved rail and road infrastructure is expected to enhance both civilian and military logistics. With the region prone to landslides and flooding, stronger, centrally executed projects aim to ensure year-round connectivity. Increased rail capacity could also reduce dependence on road transport, easing pressure on highways while ensuring steady supply movement to the Northeast.
