Siliguri Corridor highway gets ₹2,077-crore four-laning plan on NH-327
Synopsis
The Siliguri Corridor — India's narrow Chicken's Neck linking the entire Northeast to the mainland — is getting a ₹2,077-crore upgrade. The four-laning of NH-327's 31-km Bagdogra-to-Galgalia stretch includes five elephant underpasses and promises faster freight, better airport access, and stronger ties to Nepal, Bhutan and Bangladesh. It is also the BJP's clearest infrastructure signal yet in a newly won West Bengal.
Key Takeaways
Union Minister Nitin Gadkari approved a ₹2,077.18-crore project to four-lane 31.02 km of NH-327 through the Siliguri Corridor .
The stretch runs from Bagdogra (Darjeeling district, West Bengal) to Galgalia (Kishanganj district, Bihar).
Infrastructure includes three major bridges , one road over bridge , and five elephant underpasses .
The upgraded highway will improve access to Bagdogra Airport and boost connectivity toward Nepal , Bhutan , and Bangladesh .

Union Road Transport and Highways Minister Nitin Gadkari on Thursday approved a ₹2,077.18-crore project to four-lane a 31.02-km stretch of National Highway 327 running from Bagdogra in West Bengal's Darjeeling district to Galgalia in Bihar's Kishanganj district. The corridor passes through the strategically vital Siliguri Corridor — widely known as the Chicken's Neck — the sole land passage linking the northeastern states to mainland India.
What the Project Covers
The four-laning covers the Bagdogra–Panitanki–Kharibari–Galgalia section of NH-327. Infrastructure under the plan includes three major bridges, one road over bridge, five elephant underpasses, and service roads on both sides of the highway. The elephant underpasses are a notable conservation measure, designed to allow safe wildlife movement across what is an ecologically sensitive zone.
Strategic and Regional Significance
The Siliguri Corridor's importance extends well beyond domestic connectivity. Minister Gadkari noted that the upgraded highway will strengthen access toward Nepal, Bhutan, and Bangladesh, reinforcing India's neighbourhood diplomacy through physical infrastructure. The route also serves as a critical artery for the Bagdogra Airport and key towns including Naxalbari and Panitanki, where traffic congestion has long been a concern.
Economic Impact on North Bengal
The project is expected to accelerate the movement of agricultural, horticultural, and tea products from North Bengal to larger markets across India, potentially boosting incomes for local farmers, tea garden workers, and small businesses. The region's economy is heavily tied to what Chief Minister Suvendu Adhikari has termed the 'Triple-T' sectors — tea, timber, and tourism.
Political Context
The announcement comes shortly after the Bharatiya Janata Party (BJP) government led by Chief Minister Suvendu Adhikari assumed office in West Bengal in May this year. Adhikari has repeatedly stated that North Bengal infrastructure was neglected under previous Left Front and All India Trinamool Congress (TMC) governments, and has made connectivity a stated priority of his administration. The Centre's approval aligns with that political framing, channelling a major highway investment into a region the BJP has positioned as a development focus.
What Comes Next
With the project now approved at ₹2,077.18 crore, tendering and ground-level execution timelines are awaited. Once complete, the upgraded NH-327 stretch is expected to reduce travel time, ease freight movement, and improve emergency access across one of India's most geopolitically sensitive corridors.
Point of View
077-crore commitment arrives soon after the BJP's assumption of power in West Bengal, and Chief Minister Adhikari's repeated framing of North Bengal as a 'neglected' region sets up this project as both an infrastructure win and an electoral narrative. The five elephant underpasses are a welcome conservation detail, but the broader test will be execution speed — the Chicken's Neck has seen promised upgrades stall before. Whether this approval translates into completed tarmac, or remains another headline number, depends on tendering timelines and land acquisition, neither of which has been detailed yet.
