Currently, travel between Sasaram, Arrah, and Patna takes 3-4 hours due to heavy traffic on state highways. The new corridor will integrate greenfield and 10.6 km of brownfield upgrades, linking key cities such as Arrah, Grahini, Piro, Bikramganj, Mokar, and Sasaram.

The project will connect NH-19, NH-319, NH-922, NH-131G, and NH-120, ensuring seamless access to Aurangabad, Kaimur, and Patna. It will also improve connectivity to Patna and Bihta airports, four railway stations, and an inland water terminal.

Once completed, the corridor will boost regional economic growth, linking Lucknow, Patna, Ranchi, and Varanasi. The project will create 4.8 million man-days of employment, supporting the Atmanirbhar Bharat vision by fostering infrastructure, job creation, and economic development in Bihar.
