Patna: The Bihar government has unveiled a new route map for the ambitious Patna–Purnea Expressway, a key infrastructure project expected to transform connectivity in the state. The six-lane expressway, with a projected cost of Rs 18,042.14 crore, is slated for completion within three years, according to government plans.
The 225-kilometre expressway will reduce travel time between Patna and Purnea from over eight hours to just three, drastically improving regional mobility and boosting economic activity. Land acquisition has already commenced, with authorities setting a target to complete the process by 2028.
The expressway will begin at Dighbara, connecting with NH-31 Hajipur–Chhapra Road, and pass through Dumari Buzurg, Patepur, Raja Pakhar, and Laxmanpur. From there, it will continue north via Jandaha, Sarangpur, and Sarairanjan, intersecting NH-322 and reaching Chandor Madhya. The route will then cut across Chaita North, Rosda Jahangirpur (via NH-527), Devdha, and Lagma near Aura village, traversing key districts including Darbhanga, Saharsa, and Purnia.
Key points along the route include Kusheshwar Sthan, Kaddumar, Rajhanpur–Baghwa, Sonvarsha Kachhari (SH-95), and Haripur village. The final stretch runs through Barhara Kothi, Damaili, Kajri River, Parora, and near the Purnia airport, ultimately joining NH-27 between Gulab Bagh and Kaswa and ending at Mathur–Dagrua.
The expressway will include more than 160 bridges, both large and small, making it one of the most comprehensive road infrastructure projects in the region. State officials view the expressway as a key pre-election initiative that addresses long-standing demands for better connectivity in Bihar’s heartland.
