Following the development of this project, Tripura, Mizoram, Manipur, and the Barak Valley region of Assam, from the mainland and Guwahati, will experience improved connectivity along with reduced travel distance and time, along with enhanced logistics efficiency.
This greenfield project will improve inter-city connectivity between Guwahati, Shillong & Silchar, traversing through Ri Bhoi, East Khasi Hills, West Jaintia Hills, East Jaintia Hills in Meghalaya, and Cachar district in Assam.
The project route is designed to connect seamlessly with key transport networks such as NH-27, NH-106, NH-206, and NH-37, enhancing connectivity to major hubs including Guwahati, Shillong, Silchar, Diengpasoh, Ummulong, Phramer, Khlieriat, Ratachera, Umkiang, and Kalain.
Once completed, the Shillong–Silchar corridor is expected to significantly boost regional economic development by improving connectivity between Guwahati, Shillong, Silchar, Imphal, Aizawl, and Agartala. The initiative supports the government's Atmanirbhar Bharat vision by strengthening infrastructure, creating employment opportunities, and promoting socio-economic progress in Meghalaya, Assam, Manipur, Mizoram, and Tripura.
