The Indian Cabinet has approved a project to upgrade a section of NH-22 in Bihar, aiming to reduce congestion and improve travel efficiency.
On August 19, 2026, the Cabinet Committee on Economic Affairs, chaired by Prime Minister Shri Narendra Modi, approved the Upgradation of the Muzaffarpur-Sitamarhi-Sonbarsa Section of National Highway (NH) 22 to a four-lane standard in Bihar. The project, developed under the Hybrid Annuity Mode (HAM), will cost approximately Rs.3590.73 crore and span 82.578 km.
The proposed project is strategically significant due to its integration with Bihar’s expanding National Highway network and serves as a key feeder corridor connecting the India–Nepal border at Sonbarsa with economic centers like Muzaffarpur. The project aims to alleviate congestion in densely populated areas of Muzaffarpur, Muksudpur, Runni Saidpur, Thumma, Dumra, Bhutahi, and Sonbarsa.
The project is expected to facilitate faster and safer movement of passengers and freight, improve travel efficiency, and strengthen regional connectivity. It is designed for a speed of 100 kmph with an average speed of 80 kmph, featuring no at-grade median openings, ensuring fast and safe travel.
