Patna: The Bihar government has taken a significant step towards expanding Patna’s flagship riverside road project, granting terms of reference for the extension of the JP Ganga Path from Digha to Sherpur and Bihta via Maner, a move expected to transform road connectivity across western Bihar.
The proposed extension, estimated to cost Rs 6,465 crore, will span 35.65km, according to officials from the road construction department. Once completed, the project is expected to substantially reduce travel time between Patna and Koilwar, with vehicles projected to travel at speeds of 100 to 120km per hour along key stretches.
Planners say the new corridor will directly link Danapur and Shahpur markets through the Digha–Sherpur–Koilwar Ganga Path, offering a faster alternative to existing routes. The extension is also designed to ease long-distance travel, particularly for motorists heading towards Delhi via the Purvanchal Expressway from Buxar.

Beyond Bihar, the project is expected to strengthen road access to several districts in eastern Uttar Pradesh, including Ballia, Ghazipur, Mau, Azamgarh, Deoria and Gorakhpur, reinforcing Patna’s role as a regional transport hub.
A key feature of the expansion is its integration with six major bridges along the Ganga corridor: the Digha bridge, Sherpur–Dighwara bridge, Koilwar bridge, Ara–Chhapra bridge, Janeshwar Mishra bridge and the Buxar bridge. Officials say this will create a continuous, high-capacity connectivity spine along the river.
