Assam has announced a feasibility study for what would become Northeast India's first metro rail system, planned to run along or above the upcoming 121-km Guwahati Ring Road. Chief Minister Himanta Biswa Sarma confirmed during the presentation of the 2026-27 state budget on July 10, 2026, that the government will formally engage the Delhi Metro Rail Corporation (DMRC) to prepare a Detailed Project Report and structural feasibility framework for the corridor — a move that comes months after the city inaugurated the Maharaj Prithu Flyover, its longest yet, as part of a broader, years-long push to fix Guwahati's chronic traffic congestion through infrastructure rather than road-widening alone.
Background
Guwahati's traffic problem has built up over roughly two decades of rapid urban growth without proportional investment in mass transit. The city's primary response until now has been an extensive flyover-building programme: between 2020 and May 2026, a total of 18 flyovers, overbridges, extensions and underpasses were inaugurated across the city, part of what local commentary has described as Guwahati becoming a city of flyovers. That approach has physical limits, however, since flyovers add road capacity at specific congestion points without addressing the underlying volume of vehicles on the road — a gap that has kept metro rail, previously seen as economically unviable for a city of Guwahati's size, on the state government's agenda in some form for years before this feasibility study.
The scale of the underlying problem is significant for a city Guwahati's size. Roughly 13 lakh vehicles are registered in the city — including about 3 lakh four-wheelers and 6 lakh two-wheelers — a number nearly equal to Guwahati's own 2026 population, estimated at around 12.26 lakh. Vehicle registrations have been climbing by an estimated 40,000 a year in recent years, while the city's underlying road network has stayed largely static, a mismatch compounded by chronic shortage of parking space that pushes vehicles onto roadsides, and by daily commuter and freight traffic from neighbouring states, particularly Meghalaya and Nagaland, that adds further load onto Guwahati's roads without being captured in the city's own population or vehicle-registration figures.
The metro proposal is explicitly tied to the Guwahati Ring Road, a much larger infrastructure project already under construction. The National Highways Authority of India signed a concession agreement with Ahmedabad-based Dineshchandra R Agrawal (DRA) Infracon to build the 121.43-km ring road at a project cost of Rs 5,729 crore, with the Assam government separately bearing 50 per cent of land acquisition costs and around Rs 1,270 crore in state GST contribution, bringing the gross project cost to roughly Rs 7,000 crore. The concession runs for 30 years, including a four-year construction phase, with an appointed start date of January 23, 2026; construction has begun from the Baihata Chariali end. The ring road itself includes a 55-km greenfield northern bypass, a 3-km six-lane bridge over the Brahmaputra, and six-laning of the existing NH-27 — a project scale that, per the state government's own framing, creates a natural opportunity to build a mass-transit corridor alongside it from the outset rather than retrofitting one later. The ring road's own toll-based, build-operate-transfer structure — a 30-year concession that lets DRA Infracon recover its investment through user tolls over decades rather than the state paying the full construction cost upfront — is itself a financing model increasingly common in India's national highway programme, and one that could plausibly extend to a metro component if the DMRC study finds a viable public-private or hybrid funding structure for the rail corridor as well.
Key Details
The core facts of the metro announcement:
- The Assam government will engage DMRC to prepare the Detailed Project Report (DPR) and structural feasibility framework for a metro corridor along the Guwahati Ring Road.
- Finance Minister Jayanta Malla Baruah said the study will assess the technical, financial and operational viability of introducing a metro corridor along or above the proposed ring road.
- The metro would connect outlying areas including Baihata Chariali, Sipajhar and Guwahati Airport to different parts of the city, according to the project's stated vision.
- Chief Minister Sarma has ruled out a separate city-centre metro link at this stage, tying the project specifically to the ring-road alignment rather than a conventional inner-city metro network.
- If realised, this would be Northeast India's first metro rail system.
- The ring road it would run alongside carries a gross cost of roughly Rs 7,000 crore, built by DRA Infracon under a 30-year NHAI concession with a four-year construction phase, appointed date January 23, 2026.
The metro announcement follows closely on the heels of a separate, already-completed flyover milestone. On March 10, 2026, Chief Minister Sarma inaugurated the Maharaj Prithu Flyover, a four-lane structure on GNB Road connecting Dighalipukhuri to Noonmati, built at a cost of over Rs 852 crore. Described as the longest flyover in the Northeast, it became Guwahati's 30th flyover overall. Its length was reduced from an originally planned 5.05 km to 4.2 km following protests against plans to cut century-old trees along the banks of the Dighalipukhuri tank — a rare instance of a major Guwahati infrastructure project being physically redesigned in response to environmental objections rather than proceeding as originally planned. Despite the redesign, the project was completed in 28 months against an original 36-month schedule, with much of the construction reportedly carried out overnight to minimise disruption to daily traffic on one of the city's busiest corridors, an approach state officials have credited as central to finishing eight months ahead of the original schedule despite the mid-project redesign forced by the tree-protection protests.
The flyover's name honours Maharaj Prithu, a 13th-century king of the Kamarupa kingdom — the historical polity whose territory corresponds to modern Assam, with its capital located near present-day Guwahati. Prithu, of the Khen dynasty, is remembered chiefly for defeating an invading army led by Bakhtiyar Khilji in 1206 CE, using a strategy of allowing the invaders to advance deep into Kamarupa territory before cutting their supply lines, destroying a key bridge, and trapping and largely destroying the exhausted invading force. He was later defeated in 1228 CE by Nasiruddin Mahmud, son of Sultan Iltutmish, and is believed to have taken his own life rather than face capture. His successful defence against the Khilji invasion is credited with preserving the Brahmaputra valley's political and cultural independence during a period of major upheaval across northern India — a historical reference the state government has increasingly drawn on when naming major new infrastructure, reflecting a broader pattern of tying contemporary development projects to regional historical figures.
How a Guwahati metro project might be costed remains an open question the DMRC feasibility study is meant to answer, but comparable Indian tier-2 city metro projects offer a rough benchmark. Kochi Metro's first phase, 25.6 km with 22 stations, was completed at roughly Rs 202 crore per km, while its second phase, just over 11 km, is budgeted at approximately Rs 175 crore per km. Nagpur Metro's underground Phase 3 construction runs at roughly Rs 304 crore per km, reflecting the higher cost of underground versus elevated or at-grade alignments. If a Guwahati Ring Road metro followed a similar elevated-alignment cost structure to Kochi's, a corridor running any meaningful share of the 121-km ring road length would represent a multi-thousand-crore investment on top of the ring road's own roughly Rs 7,000 crore cost — underscoring why a rigorous feasibility and financial viability study, rather than a straightforward go-ahead, is the sensible first step the state has taken.

Local Impact
For residents of Guwahati's outer growth corridors — Baihata Chariali, Sipajhar and areas near the airport — a functioning metro along the ring road would represent a fundamentally different commuting option than anything currently available: a fixed-schedule, congestion-immune transit mode rather than a bus or private vehicle subject to the same traffic that flyovers only partially relieve. For a city whose commuting population has grown substantially without proportional transit investment, particularly for lower and middle-income residents living in these outer areas who commute daily into the city for work, a metro corridor could materially reduce commute times and transport costs over the long term — though this depends entirely on the DMRC feasibility study concluding the project is viable and subsequent construction actually proceeding, neither of which is guaranteed at this early stage. Airport connectivity specifically stands out among the metro's stated goals, since a fixed-schedule rail link to Guwahati Airport would give both residents and visiting travellers a congestion-proof alternative to road transport for one of the city's most time-sensitive trips, a feature many larger Indian metro systems have prioritised precisely because airport access delays carry an outsized cost in missed flights and unpredictable journey times compared to ordinary commuting.
The Maharaj Prithu Flyover's redesign in response to the Dighalipukhuri tree protests is also a notable local story in its own right: it shows that Guwahati's rapid infrastructure expansion has not proceeded entirely without local pushback, and that at least in this instance, environmental objections from residents led to a genuine change in project scope rather than being overridden. For residents near other major infrastructure corridors still under construction or planned, including the ring road itself, this precedent may shape expectations about how much influence local objections can have on project design going forward. Dighalipukhuri, a centuries-old tank in the heart of Guwahati, holds particular civic and historical significance in the city's identity, and the willingness of authorities to redesign a flagship, high-cost flyover rather than proceed with the original tree-cutting plan suggests such heritage and environmental sites retain some practical leverage even amid the city's rapid infrastructure expansion — a consideration likely to resurface as the ring road and any future metro construction move through areas with their own ecological or heritage sensitivities.
More broadly, the metro proposal and the ring road it would run alongside are part of the same integrated urban mobility vision the state government has been articulating: rather than building road capacity and mass transit as separate, sequential projects, the explicit intent is to plan them together from the outset, potentially avoiding the retrofit costs and disruption that cities which build metro systems into already-dense urban corridors typically face.
The cross-border traffic dimension is also worth noting for how a metro corridor would or would not address Guwahati's full congestion picture. Since a substantial share of daily vehicle traffic into the city originates from neighbouring states including Meghalaya and Nagaland, a metro line confined to the ring road's alignment would primarily serve commuters travelling within Assam and specifically within the Guwahati metropolitan catchment, rather than directly capturing interstate commuter and freight traffic, which would likely continue to rely on road transport regardless of metro availability. This distinction matters for realistic expectations about how much of Guwahati's overall congestion a ring-road metro could resolve on its own, even in a best-case implementation scenario.
What Happens Next
DMRC's feasibility study and DPR preparation is the immediate next step, and its conclusions — on technical viability, financial structure, expected ridership and construction cost — will determine whether the metro proposal moves toward an actual construction timeline or remains at the planning stage. No timeline for the completion of the feasibility study itself has been publicly announced, and DMRC-led DPRs for comparable metro corridors elsewhere in India have historically taken anywhere from several months to over a year to complete, depending on the complexity of the alignment and the extent of ground-survey and ridership-forecasting work required. Given that Chief Minister Sarma has already ruled out a separate city-centre link at this stage, the project's ultimate scope appears likely to stay tied specifically to the ring-road alignment rather than expand into a broader multi-line urban metro network in its initial phase.
On the ring road itself, construction is underway from the Baihata Chariali end under DRA Infracon's four-year construction window, meaning the base infrastructure the metro would run alongside is expected to reach substantial completion around 2030, based on the concession's stated construction timeline. Whether the metro corridor is built in parallel with the ring road's construction, or added afterward once the road itself is complete, has not been detailed publicly and will likely depend heavily on the DMRC study's findings and subsequent funding decisions by both the state and central governments.
Guwahati's continued flyover programme is also expected to proceed independently of the metro study, since flyovers address different, more localised congestion points than a full mass-transit corridor could on its own. With 18 flyovers, overbridges, extensions and underpasses added between 2020 and May 2026, and the Maharaj Prithu Flyover now standing as the 30th such structure citywide, further additions to that programme are likely even as the metro proposal moves through its feasibility stage — the two approaches are being pursued as complementary rather than as alternatives to each other.
Frequently Asked Questions
Will Guwahati get a metro rail system?
A feasibility study has been announced, with DMRC engaged to prepare a Detailed Project Report for a metro corridor along the 121-km Guwahati Ring Road. No construction has been approved yet — this is a study phase.

Yes. If built, it would be the first metro rail system anywhere in Northeast India.
Which areas would the metro connect?
The stated vision connects outlying areas including Baihata Chariali, Sipajhar and Guwahati Airport to different parts of the city, running along the ring road alignment.
Is there also going to be a city-centre metro line?
Not at this stage. Chief Minister Himanta Biswa Sarma has ruled out a separate city-centre metro link, tying the current proposal specifically to the ring-road corridor.
What is the Guwahati Ring Road, and how much does it cost?
A 121.43-km road project including a 55-km greenfield northern bypass, a 3-km six-lane Brahmaputra bridge and NH-27 six-laning, built by DRA Infracon at a gross cost of roughly Rs 7,000 crore under a 30-year NHAI concession.
What is the Maharaj Prithu Flyover?
Guwahati's longest flyover, a 4.2-km, four-lane structure on GNB Road connecting Dighalipukhuri to Noonmati, inaugurated March 10, 2026, at a cost of over Rs 852 crore. It is the city's 30th flyover overall.
Why was the flyover shortened from its original plan?
Its length was reduced from 5.05 km to 4.2 km after protests against cutting century-old trees along the banks of the Dighalipukhuri tank.
Who was Maharaj Prithu?
A 13th-century king of the Kamarupa kingdom, remembered for defeating an invading army led by Bakhtiyar Khilji in 1206 CE, defending the Brahmaputra valley's independence during a period of major regional upheaval.
How bad is Guwahati's traffic congestion?
Roughly 13 lakh vehicles are registered in Guwahati, a number nearly equal to the city's own 2026 population of about 12.26 lakh, with an estimated 40,000 new vehicles registered annually and a largely static road network.
How much might a Guwahati metro cost?
No official cost estimate exists yet, that is what the DMRC feasibility study is meant to determine. Comparable Indian metro projects in Kochi and Nagpur have cost between roughly Rs 175 crore and Rs 304 crore per km depending on alignment type.
