Meta Description: Patna Outer Ring Road alignment map explained with the latest 2026 route, villages, NH-131G packages, construction status, land acquisition and verification steps.
Introduction
The Patna Outer Ring Road Alignment Map is no longer a single, fixed line described by one old project proposal. In 2026, the broader Patna Ring Road is being reported as an approximately 150-km, access-controlled corridor developed in eight phases, with the Centre approving the eighth and final alignment. The network is intended to connect Patna with important locations in Vaishali and Saran, including Kanhauli, Sherpur, Sarai, Kachhi Dargah, Bidupur, Chak Sikandar, Dighwara and Didarganj.
However, approval of the overall alignment does not mean that the entire ring road is open to traffic. Different sections are at different stages: some existing or substantially completed, some under construction, one package in tender or award processing, and others still linked to revised alignment, DPR or approval activity. This distinction is essential for anyone checking a property, village or land parcel near the proposed route.

Patna Outer Ring Road: Latest Overview
The Patna Ring Road project is being developed as a peripheral highway system around the expanding Patna urban region. Its purpose is to divert long-distance, freight and inter-district traffic away from congested city roads while creating faster links between southern Patna, the Ganga crossings, Vaishali, Saran and the eastern side of the capital.
The latest 2026 description places the project at approximately 150 km and divides it into eight phases. The reported final phase is the Dighwara–Sarai northern section. The route is described as an access-controlled corridor, with several six-lane greenfield stretches, major bridges, interchanges, flyovers and underpasses.
Older official and government descriptions used different figures. The Bihar Road Construction Department website has previously described a 141-km ring road and referred to a route through Bihta, Kanhauli, Naubatpur, Dumri, Beladhi, Daniyawan, Kachhi Dargah, Bidupur, Hajipur, Sonpur, Digha and Sherpur. Earlier reports also mentioned approximately 130 km or 140 km. These figures should not automatically be treated as errors: project scope, connecting spurs, phase boundaries and revised alignments have changed over time.
For 2026, the safest explanation is that the wider approved or proposed network is approximately 150 km, while individual national-highway packages and older project records may show shorter lengths. The 150-km figure does not mean that 150 km of continuous road has already been completed.
Patna Outer Ring Road Alignment Map and Route
There is no single public, consolidated map that can safely be used as the final village-level land-acquisition map for the entire ring road. The alignment is better understood as a chain of major project nodes and separately documented packages.
Major Locations Connected by the Ring Road
Starting from the southern and western side, the alignment includes Kanhauli and the Ramnagar corridor. From there, the route connects toward Kachhi Dargah and the northern Ganga crossing at Bidupur. The northern corridor continues through or near Kalyanpur, Sarai, Astipur, Nayagaon and the Saran side before reaching Dighwara.
The route then uses the Sherpur–Dighwara Ganga bridge to link Saran with Patna’s Danapur side. The wider alignment also references Chak Sikandar and Didarganj, which help connect the ring-road system with Vaishali, eastern Patna and existing national highways. The precise road centreline, interchange position and affected plots must be checked from the relevant DPR, land plan, Gazette notification or district acquisition record rather than from a general route graphic.
Patna Ring Road Districts and Key Corridors
The principal districts associated with the current route are Patna, Vaishali and Saran. Patna contains the southern, western and Danapur-side approaches, while Vaishali and Saran contain the northern and bridge-approach corridors.
Important transport links include NH-131G, NH-19 and existing state or national highway connections around Kanhauli, Ramnagar, Kachhi Dargah, Bidupur, Sarai, Nayagaon and Dighwara. The road is planned with grade-separated junctions in key locations, but a nearby highway or village name does not by itself prove that the alignment passes through that settlement.
Patna Ring Road Route: Section-by-Section
| Section | Key locations | Latest status |
|---|---|---|
| Kanhauli–Ramnagar | Kanhauli, Naubatpur-side corridor, Ramnagar | Existing/completed or substantially progressed components; package records identify a 39.16-km six-laning corridor. |
| Ramnagar–Kachhi Dargah | Ramnagar, Dumri/Daniyawan-side links, Kachhi Dargah | Phased corridor with sections at different stages; do not treat the full route as complete. |
| Kachhi Dargah–Bidupur | Kachhi Dargah, Ganga crossing, Bidupur/Kalyanpur | Part of the northern ring-road system and connected packages. |
| Bidupur–Nayagaon | Bidupur, Sarai, Astipur, Nayagaon | 31-km six-lane EPC package listed in NHAI’s March 1, 2026 balance-for-award records. |
| Sherpur–Dighwara | Sherpur, Ganga bridge, Dighwara | Under construction, with land and approach issues requiring section-specific verification. |
| Dighwara–Sarai | Dighwara, Saran/Vaishali side, Sarai | Final-phase alignment approved or cleared in 2026; construction status should not be described as completed. |
Kanhauli–Ramnagar
The Kanhauli–Ramnagar corridor is one of the most clearly documented sections of the Patna Ring Road. A MoRTH Gazette notification covers NH-131G from km 0.00 to km 39.16 for the Kanhauli–Ramnagar section and identifies land-acquisition authority and villages for the notified stretch.
Investment and highway records describe this as a six-lane Kanhauli–Ramnagar package. Public reporting in 2026 says that parts of the Kanhauli–Ramnagar stretch have been completed or have made significant progress, but the wider ring road remains a phased project.
It is therefore more accurate to say that the section has completed or advanced components, rather than claiming that every kilometre of the final access-controlled ring is operational.
Ramnagar–Kachhi Dargah
The southern and eastern movement from Ramnagar toward Kachhi Dargah forms a crucial part of the peripheral route. Older route descriptions refer to Naubatpur, Dumri, Beladhi and Daniyawan before reaching Kachhi Dargah.
Some of these names belong to earlier phase descriptions or connecting corridors. They remain useful for understanding the geography, but they should not be used as proof of the final road centreline. A project map can change when the DPR is revised, when a bridge approach is realigned or when land and environmental constraints are resolved.
Kachhi Dargah–Bidupur and Northern Corridor
The Kachhi Dargah–Bidupur link is associated with the Ganga crossing and the northern approach into Vaishali. Bidupur and Kalyanpur are also used in NHAI package descriptions for the northern part of the Patna Ring Road.
NHAI’s “Balance For Award” status dated March 1, 2026 lists the Northern Part of Patna Ring Road Bidupur/Kalyanpur–Sarari–Astipur ending at Nayagaon, Package IV as a 31-km, six-lane EPC project under NH-131G. This is important evidence because it places the package in an award-stage record rather than a completed-road register.
In practical terms, the northern corridor is intended to create a faster route between Vaishali and Saran and improve access to the Ganga crossings. Until the relevant contract, land possession and construction records show otherwise, this package should be described as balance-for-award or award-stage work.
Sherpur–Dighwara
The Sherpur–Dighwara section is one of the most visible engineering components of the Patna Ring Road. It includes a six-lane bridge across the Ganga connecting Sherpur in Danapur with Dighwara in Saran. The bridge and its approaches form the physical link between south-bank Patna and the Saran side of the wider corridor.
Construction is underway, and public project updates have reported work on the bridge and approaches. At the same time, land possession, compensation and site identification have affected progress in parts of the corridor. A report in March 2026 stated that the bridge was under construction while Kanhauli–Sherpur was still moving through tender and land-acquisition steps.
The bridge should not be confused with the entire Sherpur–Dighwara route. A bridge being under construction does not establish that every approach road, interchange or adjoining parcel has been completed or handed over.
Dighwara–Sarai
The Dighwara–Sarai section is the most important 2026 alignment development. The Centre approved the eighth and final alignment of the broader project, with Dighwara–Sarai identified as the last phase.
The section matters because it can connect Dighwara and the Saran side with Sarai and the Vaishali-side northern corridor. Reports also link the revised northern alignment with improved access to the proposed Sonepur airport and planned industrial activity in Saran and Vaishali.
Approval of the alignment is a significant administrative step, but it is not the same as a construction award or completed highway. The DPR, statutory clearances, land acquisition, tendering and physical possession still determine when visible road work can begin on particular portions.
Villages on the Patna Ring Road Alignment
A verified, consolidated village list for the entire 2026 Patna Ring Road is not established by the authoritative public records reviewed for this article. Different notifications cover different packages, and a village mentioned in a project document may refer to an alignment segment, survey area, access road or land parcel rather than the entire settlement.
Readers should also distinguish between “alignment/project-document villages” and “villages with documented land acquisition.” The first category indicates that a village appears in an engineering or alignment record. The second requires a Gazette notification, land plan, award, possession record or district acquisition document.
Documented Villages on the Sherpur–Dighwara Section
Project documentation for the Sherpur–Dighwara section identifies villages including Balua, Sherpur, Khaspur, Mangarpal, Ganghara, Rampur Jagira, Diara Shankarpatti, Manupur, Saidpur Dighwara and Mirpur Bhual.
| Village | Project section | What the source confirms |
|---|---|---|
| Balua | Sherpur–Dighwara | Identified in project documentation for the bridge or approach alignment. |
| Sherpur | Sherpur–Dighwara | Major Patna-side project node and bridge approach location. |
| Khaspur, Mangarpal and Ganghara | Sherpur–Dighwara | Listed in the section’s project documentation. |
| Rampur Jagira and Diara Shankarpatti | Sherpur–Dighwara | Identified as alignment or project-document villages. |
| Manupur | Sherpur–Dighwara | Listed in project documentation; acquisition must be verified separately. |
| Saidpur Dighwara and Mirpur Bhual | Sherpur–Dighwara | Listed in project documentation and relevant to section-specific land checks. |
This list does not mean that every property in these villages is affected, that the entire village is being acquired or that compensation has been paid to every landholder. The alignment usually occupies only a defined strip, and the affected area may differ by plot, revenue thana, road geometry and approach design.
For the Kanhauli–Ramnagar section, the 2023 MoRTH notification identifies villages including Panapur, Newa, Kalianpur Basiawan and Ghordaur in the schedule for the notified stretch. This is a legal land-acquisition reference for that section, not a complete village list for the wider ring road.
How to Verify Whether a Village Is Actually Affected
Use the following process before buying, selling or developing land near the proposed route:
- Identify the exact project section, such as Kanhauli–Ramnagar or Sherpur–Dighwara.
- Check the relevant MoRTH Gazette notification, BhoomiRashi record, land plan schedule or NHAI project document.
- Match the village or mauza name with the plot, khata, khasra and revenue-thana details.
- Ask the district land-acquisition office whether a preliminary notification, declaration, award or possession record exists.
- Confirm the road centreline and chainage from the latest approved drawing rather than relying on a map screenshot.
The BhoomiRashi land-acquisition portal, NHAI records and district administration websites are useful starting points. For a binding property decision, obtain a written confirmation from the competent authority or consult a qualified land lawyer.
Patna Ring Road Latest Status in 2026
| Package or section | Length | Current stage |
|---|---|---|
| Kanhauli–Ramnagar, NH-131G | 39.16 km in the notified stretch | Existing/completed or substantially progressed components; land and package records remain section-specific. |
| Sherpur–Dighwara bridge and approaches | Project documents and reports use different bridge/approach lengths | Under construction; progress is not uniform across bridge and approaches. |
| Kanhauli–Sherpur, NH-131G | 8.48 km road plus approximately 1.5-km junction development; total tender length 9.98 km | Tender and bid-processing stage in current NHAI records. |
| Bidupur/Kalyanpur–Sarari–Astipur–Nayagaon, Package IV | 31 km | Listed by NHAI as a six-lane EPC balance-for-award project on March 1, 2026. |
| Dighwara–Sarai, final phase | Reported as approximately 30 km in current phase descriptions | Alignment approval or clearance stage; do not describe as completed construction. |
Completed Sections
The available evidence supports describing parts of the Kanhauli–Ramnagar corridor as completed, operational or substantially progressed, depending on the exact subsection. The Bihar government has also previously stated that land acquisition for the southern part was completed using state resources.
That information belongs to the relevant southern phase and should not be extended automatically to the northern corridor, Sherpur–Dighwara bridge or Dighwara–Sarai final phase.
Sections Under Construction
The Sherpur–Dighwara Ganga bridge is under construction. It is a major six-lane connection, but construction progress can differ between river piers, embankment approaches, junctions and land parcels. Current reporting confirms advancement, not completion of the full ring road.
Tender, DPR and Approval-Stage Sections
NHAI tender records identify the Kanhauli–Sherpur NH-131G work as a six-lane greenfield highway package with junction development linked to the Bihta–Danapur elevated corridor. The tender record shows a 9.98-km total length and an EPC contract structure. Receiving bids or processing a tender does not mean that the road has entered full-scale construction.
The 31-km Bidupur/Kalyanpur–Sarari–Astipur–Nayagaon package is specifically recorded by NHAI as balance for award as of March 1, 2026. Meanwhile, Dighwara–Sarai has moved through alignment approval activity. These are different administrative stages and should not be merged into one “under construction” label.
Land Acquisition and Compensation Status
Land acquisition is not uniform across the Patna Ring Road. It depends on the package, district, notification date and whether the land is required for the main carriageway, bridge approach, interchange, service road or utility relocation.
For Kanhauli–Ramnagar, the 2023 Gazette notification legally identifies the notified NH-131G stretch from km 0.00 to km 39.16 and provides the relevant village schedule. Earlier government information stated that land acquisition for approximately 60 km of Phase I had been completed, but this should be read as a phase-specific historical position rather than proof that all current project land is acquired.
For Kanhauli–Sherpur, current tender and local administrative reporting indicates that acquisition and compensation remained important steps before construction. The NHAI tender record confirms procurement activity, but it does not by itself establish that all land has been acquired or handed over.
For Sherpur–Dighwara, villages such as Saidpur Dighwara, Mirpur Bhual and Manupur should be treated as documented section references. They should not be presented as proof that every plot or every household in those villages has received compensation. The authoritative public material reviewed here does not establish one consolidated 2026 figure for total villages, acquired area, awardees, compensation awarded, compensation disbursed and structures affected across the entire ring road.
Landowners should therefore check four separate milestones: notification, measurement and valuation, award, and payment or possession. A compensation award may exist while physical possession is pending; similarly, a village may appear in an alignment document before plot-level acquisition is finalised.
Patna Ring Road Length, Cost and Major Features
The latest 2026 public description puts the broader access-controlled corridor at approximately 150 km and reports an estimated cost of around ₹16,000 crore. Because the project has evolved through multiple phases and packages, individual tender values and section lengths should not be added mechanically to recreate the total project cost.
Major planned features include six-lane highway sections, Ganga and tributary bridges, grade-separated interchanges, flyovers, vehicular underpasses, service connections and junction improvements. NH-131G is the national-highway identification used for important Patna Ring Road sections, including Kanhauli–Ramnagar and Kanhauli–Sherpur.
The project is being implemented through multiple agencies and arrangements, including NHAI, MoRTH and the Bihar Road Construction Department, depending on the component. The executing agency for one package is not necessarily responsible for the whole ring road.
What the Patna Ring Road Means for Connectivity
Once its separate sections are completed and connected, the ring road should give freight and through traffic an alternative to central Patna routes. It can improve movements between Patna, Vaishali and Saran, particularly through the Kachhi Dargah–Bidupur and Sherpur–Dighwara links.
The Dighwara–Sarai alignment is also strategically important for northern Bihar. Current reports connect it with Saran and Vaishali industrial access and the proposed Sonepur airport. These benefits depend on land acquisition, construction, interchanges and integration with existing highways; alignment approval alone does not deliver them immediately.
Frequently Asked Questions
What is the latest Patna Outer Ring Road alignment?
The 2026 alignment is described as an approximately 150-km, eight-phase access-controlled corridor connecting Kanhauli, Sherpur, Dighwara, Sarai, Astipur, Nayagaon, Bidupur, Kachhi Dargah, Chak Sikandar and Didarganj among other nodes. The final Dighwara–Sarai alignment has received approval or clearance, but the full corridor is not complete.
How long is the Patna Ring Road?
Current 2026 descriptions use approximately 150 km. Older records use approximately 130 km, 140 km or 141 km because the project scope and phase descriptions evolved. The applicable length depends on whether the source refers to the wider network, an earlier alignment or a specific package.
Which villages are on the Patna Ring Road?
There is no verified single village list for the entire current ring road in the public records reviewed. Sherpur–Dighwara project documentation identifies Balua, Sherpur, Khaspur, Mangarpal, Ganghara, Rampur Jagira, Diara Shankarpatti, Manupur, Saidpur Dighwara and Mirpur Bhual. The Kanhauli–Ramnagar Gazette schedule identifies Panapur, Newa, Kalianpur Basiawan and Ghordaur for its notified stretch.
Is Kanhauli–Ramnagar complete?
Parts of the Kanhauli–Ramnagar corridor are complete or substantially progressed, but the phrase should not be extended to the entire Patna Ring Road. The section contains separately documented lengths and acquisition records.
What is the status of Sherpur–Dighwara?
The six-lane Ganga bridge and approaches are under construction. Progress varies by location, and land possession and compensation issues can affect individual work fronts. It is not correct to describe the whole Patna Ring Road as operational merely because this bridge is being built.
What is the Dighwara–Sarai section?
It is the reported eighth and final phase of the broader 2026 alignment. Its approval is intended to strengthen links among Dighwara, Saran and Sarai in Vaishali, with relevance to the proposed Sonepur airport. Approval or DPR activity is not the same as construction completion.
Is land acquisition complete for the ring road?
No single statement can accurately answer that for the whole project. Acquisition is section-specific. Some southern-phase land has previously been reported as acquired, while other packages require separate checks of notifications, awards, compensation and possession.
Which agency is building the Patna Ring Road?
NHAI and MoRTH are associated with national-highway and bridge components, while the Bihar Road Construction Department is involved in state-level planning and coordination. Responsibility varies by package and should be checked in the relevant tender or project document.
What is NH-131G?
NH-131G is the national-highway number used for key Patna Ring Road sections, including the Kanhauli–Ramnagar and Kanhauli–Sherpur corridors.
How can I verify whether my village or plot is affected?
Check the latest Gazette notification, BhoomiRashi entry, land plan, chainage drawing and district land-acquisition records. Match the documents with your plot, khata, khasra and mauza details. A general Patna Ring Road map or online property listing is not sufficient proof.
Conclusion
The Patna Outer Ring Road alignment in 2026 should be read as an evolving, multi-package infrastructure network rather than a completed circular highway. The latest description is approximately 150 km across eight phases, with major nodes from Kanhauli and Sherpur to Dighwara, Sarai, Bidupur, Kachhi Dargah, Chak Sikandar and Didarganj.
The most reliable way to understand the route is to separate approved alignment from construction, tendering, DPR and land acquisition. For village or property questions, only section-specific official notifications, project drawings and district records can establish whether a particular plot is affected.
