National Highway 10 (NH-10) serves as a critical connection between the plains of Siliguri and which neighboring Indian state?

The correct answer is Sikkim. Key Points NH-10 is the lifeline for the Himalayan state of Sikkim. It starts from the Indo-Bangladesh border at Fulbari and passes through Siliguri before heading toward the Sikkim border near Sivok . The highway follows the course of the Teesta River through a steep mountain gorge. It is the only road link connecting the landlocked state of Sikkim with the rest of the Indian mainland via West Bengal. Additional Information NH-17: Connects Sivok (on NH-10) to Koch-Bihar and Tufanganj, eventually leading into Assam. It serves as the primary route for the Duars region. NH-27: A massive East-West highway that enters Bengal from Bihar (Dalkola) and exits into Assam, serving as a vital link for the entire Northeast. Chicken's Neck Corridor: The narrow strip of land in North Bengal (Siliguri corridor) through which all these critical highways (NH-10, NH-27, NH-17) must pass. Strategic Importance: Due to frequent landslides during the monsoon, NH-10 is often blocked, making its maintenance by BRO and NHAI a top priority for national logistics.
