The Centre approved the final alignment for the eighth phase of the ₹16,000 crore Patna Ring Road, clearing one of the project’s last major hurdles. The road, conceived nearly 20 years ago, aims to divert heavy traffic from Patna and improve links with neighbouring Vaishali and Saran districts.

The eight-phase corridor will connect Kanhauli, Sherpur, Sarai, Kacchi Dargah, Bidupur, Chak Sikandar, Dighwara and Didarganj. It will include multiple six-lane stretches, grade separators, flyovers, underpasses and major bridges across the Ganga and other waterways. The approved final section runs between Dighwara and Sarai and is expected to integrate several national highways, improving passenger and freight movement across north and south Bihar. Some stretches are complete; others are under construction or nearing tender stage.

• The Patna Ring Road, planned under the Bharatmala Project, will span 150 km at an estimated cost of Rs 150 billion, covering nearly 1,350 sq km.
• The six-lane, access-controlled corridor will link 12 national highways and five state highways. It will start at Kanhauli and pass through Naubatpur, Ramnagar, Kachchi Dargah, Bidupur, Hajipur, Sonepur and Dighwara before reaching Sherpur.
• Two large bridges over the Ganga are planned to connect north and south Bihar. The road is intended to bypass Patna’s city centre, ease congestion and improve commuter and freight movement.
• The project is expected to support industrial and residential expansion and create logistics and warehousing hubs along the corridor.

• The Bharatmala Project ring road is planned as a 150-kilometre, six-lane, access-controlled loop around Patna, with an estimated cost of ₹15,000 crore.
• The corridor will connect Kanhauli and Sherpur, cover nearly 1,350 square kilometres, and link 12 national highways and five state highways.
• Backed by the Bihar and central governments, it is intended to decongest the city and strengthen regional connectivity.

Land acquisition is underway for about 185 acres across multiple villages for the six-lane, 8.48-kilometre Kanhauli–Sherpur segment of the Patna Ring Road. Officials are holding field camps to help landowners submit documents and compensation claims. The national highway authority is developing the stretch to divert freight and through-traffic from Patna’s urban core and improve regional connectivity.

The segment will connect with a six-lane Ganga bridge between Sherpur in Patna district and Dighwara in Saran district. About one-third of the bridge is complete, with completion targeted for 2027. The broader ring road is planned to extend more than 170 kilometres across Patna, Saran and Vaishali districts, intersecting national and state highways.

Bids have been received for the roughly 9-kilometre Sherpur–Kanhauli stretch of the Patna Ring Road, and contractor selection is underway. The six-lane corridor, developed by the National Highways Authority of India and state authorities, is intended to divert through-traffic from central Patna and improve freight movement and connectivity across Patna, Saran and Vaishali districts.

Funding approvals and state–central cost-sharing arrangements delayed the project last year. Authorities are proceeding with land acquisition and preparatory work; notices have been issued to affected farmers, and compensation is being processed, with direct transfers to farmers’ accounts prioritised. The link interfaces with the Bihta–Danapur elevated road and other ring-road sections.
