Bihar has taken a major step towards transforming its road infrastructure with the approval of the 336-km, six-lane Buxar-Bhagalpur Greenfield Expressway. Once completed, it is expected to become the state’s longest expressway, creating a high-speed east-west corridor across southern Bihar. The biggest impact will be on travel time. The journey between Buxar and Bhagalpur, which currently takes around 10–12 hours, could come down to just 4–5 hours. The corridor is planned to improve connectivity across 13 districts, including Buxar, Bhojpur, Gaya, Nalanda, Munger, Jamui, Banka and Bhagalpur, potentially benefiting nearly 4 crore people.
The project could also become a crucial interstate link. At Buxar, the corridor is planned to connect with the Purvanchal Expressway network, creating faster movement for traffic coming from Delhi, Noida and Lucknow towards West Bengal, Assam and the Northeast while reducing dependence on congested routes through Patna. Designed as a fully access-controlled greenfield expressway, the route is expected to have only 10 entry and exit points. Major bridges and elevated stretches are planned across rivers including the Son, Punpun, Falgu and Kiul. The project is proposed to be developed through the PPP model.
Beyond faster travel, the expressway is being positioned as a major economic corridor for Bihar. Industrial zones, logistics parks and economic hubs are planned along the route, potentially giving industries such as Bhagalpur silk, Gaya textiles and agricultural businesses faster access to major national markets. For Bihar, this is more than a new highway—it could become a 336-km backbone for connectivity, industry and economic growth.
