Cabinet approves construction of 4-Lane greenfield and brownfield Patna-Arrah-Sasaram corridor in Bihar

The Cabinet Committee on Economic Affairs (CCEA), chaired by the Prime Minister Shri Narendra Modi, has approved the construction of 4-lane access controlled greenfield and brownfield Patna – Arrah – Sasaram corridor starting from Patna to Sasaram (120.10 km) in Bihar. The project will be developed on Hybrid Annuity Mode (HAM) at a total capital cost of Rs. 3,712.40 crore.

Currently, connectivity between Sasaram, Arrah and Patna relies on existing State Highways (SH-2, SH-12, SH-81 and SH-102) and takes 3-4 hours due to heavy congestion including in Arrah town. A greenfield corridor, along with 10.6 km of upgradation of existing brownfield highway, will be developed to reduce the increasing congestion, catering to the needs of densely built-up areas in places like Arrah, Grahini, Piro, Bikramganj, Mokar and Sasaram.

The project alignment integrates with major transport corridors, including NH-19, NH-319, NH-922, NH-131G, and NH-120, providing seamless connectivity to Aurangabad, Kaimur, and Patna. Additionally, the project will also provide connectivity to 02 airports (Patna’s Jay Prakash Narayan International Airport and upcoming Bihita airport), 04 major railway stations (Sasaram, Arrah, Danapur, Patna), and 01 Inland Water Terminal (Patna), and enhance direct access to Patna Ring Road, facilitating faster movement of goods and passengers.

Upon completion, the Patna-Arrah-Sasaram Corridor will play a pivotal role in regional economic growth, improving connectivity between Lucknow, Patna, Ranchi, and Varanasi. The project aligns with the government’s vision of Atmanirbhar Bharat, enhancing infrastructure while generating employment and fostering socio-economic development in Bihar. The project will also generate 48 lakh man days employment, and will open new avenues of growth, development and prosperity in developing regions in and around Patna.
