On October 1, 2025, the Cabinet Committee on Economic Affairs (CCEA) approved the widening and improvement of the existing carriageway to 4 lanes of the Kalibor- Numaligarh section of NH-715 in Assam. This includes the implementation of Wildlife friendly Measures proposed on the Kaziranga National Park (KNP) Stretch. The total length of the carriageway is 85.675 km with a financial implication of Rs.6957 crore.
The project will be developed on Engineering, Procurement and Construction (EPC) Mode and includes construction of an elevated corridor of about 34.5 km, covering entire cross movement of wildlife from Kaziranga National Park to Karbi- Anglong Hills. Additionally, the project includes upgradation of 30.22 km of existing road, and construction of 21 km of greenfield bypasses around Jakhalabandha and Bokakhat.
The project alignment integrates with 2 major National Highways (NH-127, NH-129) and 1 State Highways (SH-35). The upgraded corridor will connect with 3 Railway Stations (Nagaon, Jakhalabandha, Vishwanath Charli), and 3 Airports (Tezpur, Liabari, Jorhat). This project will improve connectivity to 02 Socio-Economic Nodes and 08 Tourist and religious places.
The project will generate approximately 15.42 lakh person-days of direct and 19.19 lakh person-days of indirect employment. The expected Annual Average Daily Traffic (AADT) in FY-25 is estimated at 13,800 Passenger Car Units (PCU).

The Cabinet Committee on Economic Affairs (CCEA) chaired by the Prime Minister Shri Narendra Modi, has
approved widening and improvement of existing carriageway to 4 lane of Kalibor- Numaligarh section of NH-
715 including Implementation of Wildlife friendly Measures Proposed on Kaziranga National Park (KNP)
Stretch in Assam. The project will be developed on on Engineering, Procurement and Construction (EPC)
Mode with a Total Length of 85.675 km and Total Capital Cost of Rs.6957 crore.
The existing Kalibor- Numaligarh section of NH-715 (old NH-37) has a configuration of 2-lane with/without
paved shoulders, passing through densely built-up areas of Jakhlabandha (Nagaon) and Bokakhat (Golaghat)
towns. A major part of the existing highway passes either through the Kaziranga National Park or along the
southern boundary of the park, having restricted right of way (ROW) of 16 to 32 metres further aggravated by
substantially poor geometrics. During the monsoons, the area inside the park gets flooded leading to the
movement of the wildlife from the park towards the elevated Karbi-Anglong Hills by crossing the existing
highway. The heavy round-the-clock traffic on the highway results in frequent accidents and deaths of wild
animals.
To address these challenges, the project will involve construction of an elevated corridor of about 34.5 km,
covering entire cross movement of wildlife from Kaziranga National Park to Karbi- Anglong Hills for free
and un-interrupted passage of wildlife along with upgradation of 30.22 km of existing road and construct a 21
kms of greenfield bypasses around Jakhalabandha and Bokakhat. This will decongest the existing corridor,
improve safety, and enhance the direct connectivity between Guwahati (the State Capital), Kaziranga National
Park (tourism destination), and Numaligarh (an industrial town).
The project alignment integrates with 2 major National Highways (NH-127, NH-129) and 1 State Highways
(SH-35), providing seamless connectivity to key economic, social, and logistics nodes across Assam.
Additionally, the upgraded corridor will enhance multi-modal integration by connecting with 3 Railway
Stations (Nagaon, Jakhalabandha, Vishwanath Charli), and 3 Airports (Tezpur, Liabari, Jorhat) thereby
facilitating faster movement of goods and passengers across the region. The project alignment improves
connectivity to 02 Socio-Economic Nodes, 08 Tourist and religious places, thereby strengthening regional
economic growth and religious tourism.
Upon completion, the Kalibor- Numaligarh section will play a pivotal role in regional economic growth,
strengthening connectivity between major tourism, industrial and economic centers, boosting tourism toKaziranga National Park, and opening new avenues for trade and industrial development. The project will also
generate approximately 15.42 lakh person-days of direct and 19.19 lakh person-days of indirect employment,
and will open new avenues of growth, development and prosperity in surrounding regions.
