Siliguri Corridor
Geography and Strategic Significance
The Siliguri corridor, popularly called the "Chicken's Neck," is a narrow strip of land in northern West Bengal that forms the sole land connection between mainland India and its northeastern states, making its geography a recurring subject in both physical and strategic geography questions.
- Width: narrows to approximately 20-22 km at its thinnest point (some estimates cite figures as low as 17 km)
- Connects mainland India to eight northeastern states: Arunachal Pradesh, Assam, Meghalaya, Manipur, Mizoram, Nagaland, Tripura and Sikkim
- Bordered by Nepal to the west, Bangladesh to the south, and Bhutan to the north, with the China-Bhutan-India tri-junction near the Chumbi Valley in proximity
- Virtually all surface trade and troop movement between the northeastern states and the rest of India passes through this corridor, making it a single point of vulnerability
