The Cabinet Committee on Economic Affairs (CCEA), chaired by Prime Minister Narendra Modi, on Thursday approved the construction of a 135.87-km four-lane access-controlled Guwahati-Tezpur corridor on National Highway-15 in Assam at an estimated cost of ₹8,970.20 crore.
The project will be executed under the Build-Operate-Transfer (BOT) Toll model and is expected to significantly improve connectivity between Assam and Arunachal Pradesh while strengthening transport infrastructure in the Northeast.
According to an official statement, the new corridor will decongest the existing NH-27 (East-West Corridor) on the southern bank of the Brahmaputra and substantially reduce travel time between Guwahati and Tezpur. The project is expected to double average travel speeds, cut journey time by nearly half, improve road safety, enhance fuel efficiency and lower vehicle operating costs.
A key feature of the project is the construction of a 4.9-km Emergency Landing Facility (ELF) on the Tezpur bypass. The facility has been planned in coordination with the Indian Air Force and will enable emergency aircraft operations when required.

The corridor will include five major bypasses spanning 58.7 km to ease congestion in densely populated towns, including Baihata Chariali, Sipajhar, Kharupetia, Dekiajuli and Tezpur.
The project also envisages extensive supporting infrastructure, including 15 major bridges, 30 minor bridges, 19 flyovers, 46 underpasses, an elephant underpass on the Tezpur bypass, and around 210 km of service roads to facilitate local traffic movement along the access-controlled highway.
The upgraded corridor is expected to improve connectivity to eight PM Gati Shakti economic nodes, including industrial parks, two aspirational districts—Darrang and Udalguri—along with major tourist destinations such as Kamakhya Temple, Kaziranga National Park and Orang National Park.
It will also strengthen links to key logistics hubs, including three major railway stations, two airports and two inland waterway terminals, enabling faster movement of passengers and freight.
The government said the project would serve as a major catalyst for regional economic growth, tourism, trade and industrial development while enhancing overall connectivity across the Northeast.
