The Cabinet Committee on Economic Affairs, 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 at a total capital cost of ₹8,970.20 crore under the National Highways (Original) scheme.
The project includes several significant infrastructure components: a 4.9 km Emergency Landing Facility (ELF) on the Tezpur Bypass coordinated with the Indian Air Force, 58.7 km of bypasses across five major sections (Baihata Chariali, Sipajhar, Kharupetia, Dekiajuli, Tezpur) to ease congestion in densely populated areas, and extensive supporting infrastructure including 15 major bridges, 30 minor bridges, 19 flyovers, 1 elephant underpass (on Tezpur bypass), 46 underpasses, and 210 km of service roads to maintain cross-traffic movement in the access-controlled corridor.
The project is expected to deliver substantial transportation benefits, including a 100% increase in average travel speeds, 50% reduction in travel time, improved road safety, enhanced fuel efficiency, and lower vehicle operating costs. It will provide seamless connectivity to key economic, social, and logistics nodes across Assam and Arunachal Pradesh, specifically connecting to 8 PM Gati-Shakti Economic Nodes (industrial parks), 2 social nodes (aspirational districts of Darrang and Udalguri), 3 tourist nodes (Maa Kamakhaya Temple, Kaziranga National Park, Orang National Park), and 7 logistic nodes (3 major railway stations, 2 airports, 2 waterway terminals).
