The Bihar government approved the northern Dighwara-Sarai alignment in March 2026. The ring road is being developed as an approximately 150 km access-controlled corridor, with the project cost reported at around Rs 16,000 crore. The state subsequently moved the proposal for central approval after officials were directed to prepare the detailed project report for the section. The alignment was discussed during a review of National Highway projects in Bihar and was linked to road access for the proposed greenfield airport at Sonepur and development in Vaishali and Saran.<\/span><\/p>\n

The Center’s June approval made Dighwara-Sarai the eighth and final alignment of the Patna Ring Road project. The corridor has been planned through multiple phases, with strategic locations including Kanhauli, Sherpur, Sarai, Kachhi Dargah, Bidupur, Chak Sikandar, Dighwara and Didarganj forming part of the wider network.<\/span><\/p>\n

Patna Ring Road project status<\/span><\/h2>\n

The Patna<\/a> Ring Road is being executed through separate road and bridge packages. The Kanhauli-Ramnagar section is a 39.16 km six-lane package of NH-131G. NHAI’s project records identify the section as part of the Patna Ring Road and record its appointed date as March 8, 2021. Earlier government records put the package cost at Rs 913.15 crore.<\/span><\/p>\n

The Kachhi Dargah-Bidupur project is a separate 19.76 km six-lane greenfield bridge corridor. According to the Bihar government, it includes a 9.76 km main bridge and 10 km of approach roads. The project was still listed as work in progress in the Bihar State Road Development Corporation’s project records dated May 31, 2026.<\/span><\/p>\n

The project has, however, already opened part of the corridor. The Bihar Chief Minister’s Office said the first phase from Kachhi Dargah to Raghopur Diara, measuring 4.57 km, was inaugurated in June 2025. The remaining sections toward Bidupur were still under construction in February 2026.<\/span><\/p>\n

The Ramnagar-Kachhi Dargah section is a 14.5 km six-lane greenfield corridor. NHAI’s 2025 project publication records the section as part of the wider connectivity works around the Patna region.<\/span><\/p>\n

The Sherpur-Dighwara section is a 14.52 km six-lane bridge and approach package forming part of Patna Ring Road NH-131G. NHAI records show an appointed date of September 5, 2023, while the Ministry of Road Transport and Highways has recorded an awarded cost of Rs 3,012.27 crore.<\/span><\/p>\n

MoRTH’s August 2026 parliamentary project data recorded physical progress of 20.60% for the Sherpur-Dighwara package. It listed September 5, 2027 as the original completion date and March 31, 2029 as the revised completion date.<\/span><\/p>\n

How the Patna Ring Road will improve connectivity<\/span><\/h2>\n

The road is intended to provide an alternative route for traffic that does not need to enter central Patna. This is particularly relevant for heavy vehicles moving between different parts of Bihar. The planned corridor is designed to take through traffic around the city rather than through its existing urban road network.<\/span><\/p>\n

The Ganga crossings form an important part of that connectivity. The Kachhi Dargah-Bidupur project connects NH-30 near Kachhi Dargah in Patna with NH-103 near Bidupur in Vaishali. The Bihar government has said the crossing will provide an alternative connection between north and south Bihar and reduce pressure on the Mahatma Gandhi Setu.<\/span><\/p>\n

The Sherpur-Dighwara package will add another six-lane Ganga crossing to the Patna Ring Road network. NHAI identifies it as a specific component of NH-131G and the Patna Ring Road.<\/span><\/p>\n

The Dighwara-Sarai alignment adds the northern section discussed by Bihar officials in connection with the proposed Sonepur airport and industrial development in Vaishali and Saran.<\/span><\/p>\n

Ganga Bridges form key links in the Patna Ring Road<\/span><\/h2>\n

The Ganga crossings are among the largest structures associated with the wider road network. The Kachhi Dargah-Bidupur project covers 19.76 km, including a 9.76 km main bridge. The Bihar government records the project under its ongoing works and has divided construction into phases. The first 4.57 km section from Kachhi Dargah to Raghopur Diara was opened in June 2025, while work on the remaining sections was continuing in February 2026.<\/span><\/p>\n

The Sherpur-Dighwara crossing is shorter at 14.52 km but forms a separate six-lane bridge and approach package under Patna Ring Road NH-131G. NHAI awarded the package for Rs 3,012.27 crore.<\/span><\/p>\n

The two projects are at different stages. The Kachhi Dargah-Bidupur corridor has already opened part of its alignment, while Sherpur-Dighwara remains under construction.<\/span><\/p>\n

Areas likely to see real estate activity<\/span><\/h2>\n

The Patna Ring Road is expected to influence property activity across several peripheral areas as new road links improve access around the city. The Dighwara-Sarai alignment brings the northern side of the ring road closer to Dighwara, Sonepur, Sarai and parts of Vaishali and Saran, while the wider route connects with areas such as Kanhauli, Sherpur, Kachhi Dargah, Bidupur and Ramnagar.<\/span><\/p>\n

The Sonepur-Dighwara belt could receive additional attention because the final alignment is linked with the proposed Sonepur greenfield airport and planned industrial development in Vaishali and Saran.<\/span><\/p>\n

On the Patna side, Kanhauli, Sherpur, Ramnagar and Kachhi Dargah are already part of major road packages associated with the ring road network. The Sherpur-Dighwara package includes a 14.52 km Ganga bridge and approaches, while the Kachhi Dargah-Bidupur corridor provides another north-south connection outside central Patna.<\/span><\/p>\n

Final alignment clears a key hurdle, but construction continues<\/span><\/h2>\n

The Center’s approval settles the final alignment of the Patna Ring Road, but the project still has several execution stages ahead. The wider network includes the 39.16 km Kanhauli-Ramnagar package, the Kachhi Dargah-Bidupur Ganga bridge project, the Ramnagar-Kachhi Dargah corridor and the Sherpur-Dighwara bridge package. Their construction schedules and stages are separate from the newly approved Dighwara-Sarai alignment.<\/span><\/p>\n

Land acquisition is also continuing on parts of the ring road. In July 2026, the Central government issued a Section 3D notification acquiring land in Patna district for the Ring Road stretch from Km 0 to Km 8.484. The notification covered land in Kanhauli and Painal villages.<\/span><\/p>\n

The significance of the latest clearance is therefore specific. The Center has approved the final alignment, removing an important planning step. The next phase will depend on DPR preparation, land acquisition, construction, and the eventual integration of the separate packages into a continuous Patna Ring Road corridor.<\/span><\/p>\n
