About the Shillong–Silchar Greenfield Corridor

• The Shillong–Silchar Greenfield High-Speed Corridor is a 166.8 kilometre long highway project connecting Mawlyngkhung near Shillong in Meghalaya to Panchgram near Silchar in Assam.
• The project is implemented by the National Highways and Infrastructure Development Corporation Limited, an agency working under the Ministry of Road Transport and Highways.
• The total estimated capital cost is about ₹22,864 crore.

• Around 144.8 kilometres falls in Meghalaya, while 22 kilometres lies in Assam.
• One 31 kilometre from Mawlyngkhung to Panchgram has an estimated cost of ₹2,206.55 crore.

Objectives of the Corridor

• To reduce travel time and transportation costs between Shillong, Guwahati and Silchar.
• To decongest the existing National Highway 6, which currently faces heavy traffic and bottlenecks.
• To improve regional connectivity across Northeast India, especially linking Assam, Meghalaya, Mizoram, Manipur and Tripura.

Strategic and Economic Significance
