The Cabinet Committee on Economic Affairs, chaired by the Prime Minister Shri Narendra Modi, today
has approved the Upgradation of the Muzaffarpur-Sitamarhi-Sonbarsa Section of NH-22 to four-Lane
Standard in Bihar. The project will be developed on Hybrid Annuity Mode (HAM) at a total capital cost of
Rs.3590.73 crore with a total length of 82.578 km.
The proposed project holds significant strategic and economic relevance due to its integration with Bihar’s
expanding National Highway network. It acts as a key feeder corridor connecting the India–Nepal border
at Sonbarsa with economic centers like Muzaffarpur at NH-27 (East–West Corridor). The project will
significantly reduce congestion in densely populated areas of Muzaffarpur, Muksudpur, Runni Saidpur,
Thumma, Dumra, Bhutahi, and Sonbarsa.
The project is expected to enable faster and safer movement of passengers and freight, improve travel
efficiency and strengthen regional connectivity. It has been designed for a speed of 100 kmph with an
average speed of 80 kmph, having no at-grade median openings, ensuring fast and safe travel.
Planned in accordance with the principles of the PM GatiShakti National Master Plan, the project will
enhance multimodal integration by improving connectivity to key economic, social and logistics nodes,
including industrial areas and major railway stations. Improved connectivity will facilitate efficient
movement of goods and agricultural supply chains, support regional economic growth, and provide better
access to important cultural and religious destinations such as the Buddhist Circuit and historic Janaki
Punaura Dham Temple, Sitamarhi.
The Muzaffarpur–Sitamarhi–Sonbarsa stretch of NH-22 holds significant strategic and economic
relevance, ensuring seamless linkage to the national freight grid. It is in synergy with existing corridors
such as NH-31 and NH-122 enhances connectivity to industrial zones like Barauni and riverine logistics
hubs along the Ganga It also enhances cross-border passenger and cargo movement via the nearby Land
Port at Bhithamore.
In addition, the project has provision for seven Major Bridges (including a 340m long major bridge over
the perennial Bagmati River), three Railway Over Bridges (ROBs), and two Flyovers (1170m & 270m) to
maintain cross movement of the traffic and ensure safe, high-speed travel.
The project will increase average travel speeds, reduce travel time, and improve overall road safety, fuel
efficiency, and vehicle operating costs, thereby enhancing regional mobility and socio-economic
development.The project provides seamless connectivity to key economic, social, and logistics nodes across Bihar.
Additionally, the upgraded corridor will enhance connectivity to five PM Gati-Shakti Economic Nodes
(four Industrial Estates and one Mega Food park), four Social Nodes (Baba Garibnath Temple, Mata Janki
Temple, Punaura Dham, Muzaffarpur & Sitamarhi aspirational Districts), and two Logistic Nodes
(Muzaffarpur & Sitamarhi Railway Stations), thereby facilitating faster movement of goods and
passengers across the region.
