Patna Ring Road To Connect Kanhauli With Sherpur

21 Apr 2026 CW Team

A new ring road is planned to be developed around Patna under the Bharatmala Project, spanning 150 km at an estimated cost of Rs 150 bn. The corridor will cover nearly 1,350 square kilometres and is designed to link 12 national highways and five state highways, significantly strengthening regional connectivity. The scheme is being advanced as one of the largest mobility projects in the region.

The project is designed as a six-lane access-controlled corridor forming a complete loop around the city and aims to decongest Patna while providing a more organised urban framework. It is supported by the Government of Bihar and the central government and is expected to shape long-term urban planning and mobility in the state capital. The planning envisions access control and grade separations to expedite through traffic and limit urban disruptions.

The ring road will begin at Kanhauli and pass through Naubatpur, Ramnagar, Kachchi Dargah, Bidupur, Hajipur, Sonepur, Dighwara and Sherpur, enabling traffic to bypass the city centre entirely. By facilitating uninterrupted movement for commuters and freight vehicles between surrounding districts the corridor should reduce pressure on existing urban roads. Planners anticipate improved journey times and more reliable freight links across the region.

A major feature is integration with Bihar’s wider transport network and the construction of two large bridges over the Ganga, which will improve connectivity between north and south Bihar and enhance long-distance travel efficiency. The initiative is expected to catalyse industrial growth, residential expansion and the development of logistics and warehousing hubs along the corridor. By diverting heavy traffic away from central roads the project should also improve road safety and support business activity, tourism and investment, contributing to sustained economic development in the area.
