The Cabinet Committee on Economic Affairs (CCEA), chaired by Prime Minister Narendra Modi, has approved the development of a 135.871 km 4-lane access-controlled Guwahati-Tezpur Corridor along NH-15 in Assam. The project will be developed on Built-Operate-Transfer (BOT) Toll Mode with a total capital cost of ₹8,970.20 crore under National Highways (Original).
The project includes construction of 05 major bypasses totaling 58.7 km to ease congestion through densely populated areas including Baihata Chariali, Sipajhar, Kharupetia, Dekiajuli, and Tezpur. Key infrastructure elements comprise 15 major bridges, 30 minor bridges, 19 flyovers, 46 underpasses, and 210 km of service roads to maintain cross-traffic movement. A significant feature is the 4.9 km Emergency Landing Facility (ELF) on Tezpur Bypass, finalized in coordination with the Indian Air Force, which will also help decongest existing NH-27 on the south side of Brahmaputra river. The project includes specialized infrastructure such as 01 Elephant Under Pass in Tezpur bypass.
The upgraded corridor is expected to increase average travel speeds by 100%, reduce travel time to half, improve overall road safety, enhance fuel efficiency, and lower vehicle operating costs. It will provide seamless connectivity to key economic, social, and logistics nodes across Assam and Arunachal Pradesh, including 08 PM Gati-Shakti Economic Nodes (industrial parks), 02 social nodes (aspirational districts of Darrang and Udalguri), 03 tourist nodes (Maa Kamakhaya Temple, Kaziranga National Park, Orang National Park), and 07 logistic nodes (03 major railway stations, 02 airports, 02 waterway terminals).
