The Cabinet Committee on Economic Affairs, chaired by Prime Minister Narendra Modi, has approved the development, maintenance, and management of a 166.80 km 4-lane Greenfield Access Controlled High-Speed Corridor on National Highway 06. The corridor will span from Mawlyngkhung near Shillong in Meghalaya to Panchgram near Silchar in Assam and will be constructed on Hybrid Annuity Mode (HAM), with a total capital investment of ₹22,864 crore.
Of the total stretch, 144.80 km falls in Meghalaya and 22.00 km in Assam. The corridor is expected to significantly improve traffic flow between Guwahati and Silchar, enhancing connectivity to the northeastern states of Tripura, Mizoram, Manipur, and the Barak Valley region of Assam. This will not only reduce travel distance and time but also enhance national logistics efficiency.
By boosting connectivity between Assam and Meghalaya, the project is set to drive economic development, especially in Meghalaya’s industrial belts known for cement and coal production. The corridor will also improve access for domestic and international tourists flying into Guwahati, Shillong, and Silchar airports, thereby strengthening tourism across scenic destinations in the North-East.
The project passes through key districts including Ri Bhoi, East Khasi Hills, West Jaintia Hills, and East Jaintia Hills in Meghalaya, and Cachar in Assam. It will ease congestion on the existing NH-06 and support the PM Gati Shakti National Master Plan by enhancing the region’s transport infrastructure.
Strategically aligned with major national highways such as NH-27, NH-106, NH-206, and NH-37, the corridor will enable seamless connectivity to major towns and cities including Guwahati, Shillong, Silchar, Diengpasoh, Ummulong, Phramer, Khliehriat, Ratacherra, Umkiang, and Kalain.

The project is a key milestone under the Atmanirbhar Bharat vision, promising infrastructure expansion, employment generation, and socio-economic upliftment in Meghalaya, Assam, Manipur, Mizoram, and Tripura.
