UP's First Double-Decker Flyover: Shahberi, Greater Noida | Full Details, Cost & Timeline

Greater Noida has proposed Uttar Pradesh's first double-decker flyover in Shahberi, a 1.4 km, six-lane structure designed to carry traffic on two stacked levels instead of one. The project is an engineering solution to a major space constraint along one of Greater Noida West's busiest corridors. GNIDA has finalised the concept and presented it to the National Highways Authority of India (NHAI), which has sought a Detailed Project Report (DPR) before granting further approvals. With construction yet to begin, here's everything you need to know about the project and how it compares with similar double-decker corridors across India.

Project Detail	Status

The Traffic Problem This Solves

Greater Noida West has grown into one of the NCR's largest residential belts over the past decade. Big townships including Gaur City, Panchsheel Greens, Nirala Estate, Ace City, Fusion Homes, Gulshan Bellina and Supertech Eco Village all funnel their daily traffic through the same narrow corridor toward Ghaziabad and Delhi.

There's a real number behind the congestion complaints: more than 10,000 vehicles pass through the Republic Crossing junction every single day, according to authority officials cited in early 2025 reporting, and that count was expected to climb further once Noida International Airport at Jewar became operational (it started commercial flights in June 2026). Add school buses, delivery trucks, commercial vehicles and autorickshaws into the mix, and the picture gets worse during monsoon, when standing water on the existing road slows everything to a crawl.

The core structural problem is simple: there's no direct link from Greater Noida West's arterial 130 metre road to the Delhi Meerut Expressway. Everyone gets routed through the same choke point.

Why Double Decker, Specifically

This is where the project gets genuinely interesting from an engineering standpoint, and it's worth explaining properly rather than glossing over.

A standard 4 lane flyover needs roughly 15 metres of clear width to accommodate the carriageway, medians and safety margins. When GNIDA's project team, led by GM Project A.K. Singh, surveyed the Shahberi site, they found only 14 metres available. That one metre shortfall would normally force a compromise: either narrower lanes, fewer lanes, or a costly land acquisition fight to widen the corridor.

Instead, the authority worked out a double decker alternative with its consultants. By stacking two 3 lane decks on top of each other, each running one way traffic, the project delivers 6 total lanes inside a 12 metre footprint, less width than even the original 4 lane plan needed. It's essentially trading horizontal space for vertical space.

The structure will rest on U shape piers, a design choice that lets the existing ground level road keep functioning as a service lane throughout construction and after the flyover opens. That matters practically: local shops, societies and residents along Shahberi retain uninterrupted access instead of losing the road to a construction shutdown.

Where the Approval Process Actually Stands

It helps to separate the stages clearly, because "approved" gets used loosely in headlines:

1. CRRI feasibility study (2025): The Central Road Research Institute recommended an elevated road solution for the original single deck version and conducted a site assessment.
2. GNIDA approval of the CRRI recommendation (early 2025): The authority board signed off on proceeding with a DPR for a single deck, 4 lane elevated structure, then estimated around 3.8 to 4 km long and 16 metres wide, running from the Iteda roundabout to NH 9.
3. GDA ramp clearance (mid 2025): The Ghaziabad Development Authority separately approved a 200 metre ramp on its side of the boundary.
4. Double decker redesign finalised (July 2026): After the width constraint came to light, GNIDA locked in the current 1.4 km, 6 lane, two level design.
5. Presented to NHAI (July 2026): GNIDA's project department gave NHAI a formal presentation of the new design.
6. DPR under NHAI review (ongoing): NHAI has asked for a detailed project report before it will commit to construction.

What hasn't happened yet: financial sanction, tender issuance, contractor appointment, and construction itself. None of these have started.

Engineering Specifics: What's Confirmed and What Isn't

Detailed technical parameters like pier spacing, exact superstructure type, design speed, load class and drainage design typically get finalised only once a DPR clears review, and that review is still underway here. Rather than guess at numbers, it's more useful to state plainly what's public and what isn't:

Confirmed: U shape pier substructure design, 12 metre overall width, 6 lanes across two decks, one way traffic per deck. Not yet released: pier spacing, superstructure type (whether precast segmental, PSC girder, or another method), exact deck height, design speed, load class or IRC design standard, crash barrier specifications, drainage plan.

This gap is normal at this stage of a project, not a sign of neglect. Once NHAI clears the DPR, these specifications typically become public through the tender documents.

How Shahberi Compares to India's Other Double Decker Flyovers

This is where deeper research actually changes the picture, because a few widely repeated assumptions about comparable projects don't hold up once you check the primary reporting.

The pattern that emerges: Nagpur, Hyderabad's planned corridor, and Delhi's MB Road project all combine road traffic with a metro line on a shared structure. Patna looks similar on paper but is actually road only; its metro line runs on a separate, rerouted alignment nearby rather than stacked on the same flyover. Shahberi follows the Patna pattern rather than the Nagpur or Delhi one: it's a pure traffic capacity fix, with no metro component announced, built double decker purely because the available width couldn't support a standard single deck flyover.

What It Should Deliver for Commuters

Once operational, the flyover is expected to give Greater Noida West direct access to the Delhi Meerut Expressway without funneling through the current bottleneck at Republic Crossing. The jump from 4 planned lanes to 6 actual lanes, inside a smaller footprint, gives it more headroom for future traffic growth than the original single deck plan would have. And the U shape pier design means the ground level road stays usable throughout, avoiding the kind of prolonged local disruption that flyover projects often cause.

There's a reasonable case for a real estate effect too, though no dedicated study for this specific project has been published. Infrastructure announcements like the Aqua Line metro extension and the long discussed FNG Road corridor have historically shifted buyer interest in nearby NCR pockets well before construction finished. Local real estate voices, including a statement from Karyan Group's director in July 2026 coverage, expect a similar pattern for Shahberi and Crossings Republik.

What's Genuinely Unresolved

Two points are worth flagging plainly rather than smoothing over:

Length and completion timeline: One industry report from July 2026 describes the project as 2.5 km with a 2028 completion target under NHAI execution. GNIDA's own project team, in the same period, describes the structure as 1.4 km with no completion date attached. Until GNIDA or NHAI issues a formal notice, treat 1.4 km and no confirmed completion date as the more reliable figures, since they trace directly to an on record GNIDA official rather than a secondary industry account.

Funding split: Some 2025 reports say NHAI will fund the project outright, given its connection to the Delhi Meerut Expressway. A 2026 account suggests GNIDA and GDA will share the cost instead. No official, itemised funding agreement has been published by either authority.

Bottom Line

This will be Uttar Pradesh's first double decker flyover, and the reasoning behind it is genuinely sound engineering: fitting 6 lanes into 12 metres where a conventional flyover needed 15 for just 4. Unlike most of its peers around the country, it's a road-only structure with no metro component, closer in spirit to Patna's approach than Nagpur's or Delhi's. The next real milestone to watch for is NHAI clearing the detailed project report. Everything else, financial sanction, tendering, and construction, sits behind that gate.

Frequently Asked Questions

Where exactly is UP's first double-decker flyover located?

In Shahberi, Greater Noida West, connecting the 130-metre road to the Delhi-Meerut Expressway via Crossings Republik in Ghaziabad.

Why is it being built as a double-decker instead of a normal flyover?

The site only had 14 metres of usable width, while a standard 4-lane flyover needs about 15 metres. The double-decker design fits 6 lanes into just 12 metres by stacking two 3-lane decks instead of building one wide deck.

Who is building this flyover?

The Greater Noida Industrial Development Authority (GNIDA) is the lead authority. NHAI is currently reviewing the detailed project report and is expected to be involved in execution given the flyover's link to the Delhi-Meerut Expressway.

What is the current estimated cost?

Around ₹900 crore, up from an earlier ₹400 crore estimate for the original single-deck, 4-lane version.

Why did the cost nearly double?

The switch from a single-level to a two-level structure requires more complex foundations, piers and decking, which pushed the estimate up.

Has construction started?

No. The design has been finalised and presented to NHAI, but the DPR review, financial approval, tendering and construction are all still pending.

When will construction begin?

No official start date has been confirmed by GNIDA or NHAI.

When will the flyover be completed?

No confirmed completion date exists from GNIDA or NHAI. One industry report cites 2028, but this figure isn't corroborated by GNIDA's own on-record statements.

How long is the flyover?

1.4 km, based on GNIDA's project team. A separate report cites 2.5 km; the two figures haven't been reconciled publicly.

How wide is it, and how many lanes does it have?

12 metres wide, with 6 total lanes, 3 lanes on each of the two decks.

Does traffic move in both directions on each deck?

No. Each deck carries one-way traffic, so one level handles Greater Noida West to Crossings Republik traffic and the other handles the reverse direction.

Will there be a metro line on this flyover?

No. Unlike Nagpur's or Delhi's double-decker projects, this is a road-only structure with no metro component announced.

Will construction disrupt the existing road in Shahberi?

The flyover uses U-shape piers specifically so the existing ground-level road can keep functioning as a service lane during and after construction, minimising disruption to local shops and residents.

How does this compare to Nagpur's double-decker flyover?

Nagpur's is longer (5.67 km overall), cost less (₹573 crore), and combines a metro line and, in places, a rail track above road traffic. Shahberi is shorter, costs more, and carries road traffic only.

Is this similar to Patna's double-decker flyover?

Yes, more so than Nagpur's or Delhi's. Patna's Ashok Rajpath flyover is also road-only. Its nearby metro line was actually rerouted away from the flyover corridor rather than integrated into it.

Who will fund the project, GNIDA, GDA, or NHAI?

This is unresolved. Some 2025 reports point to NHAI funding it given the national highway connection; a 2026 report suggests a GNIDA-GDA cost split. No official funding agreement has been published.

How much daily traffic does this corridor currently carry?

Over 10,000 vehicles pass through the Republic Crossing junction daily, according to authority officials cited in early 2025 reporting, a number expected to rise further with Noida International Airport now operational.

Will this flyover help with access to Noida International Airport (Jewar)?

Indirectly, yes. It's expected to ease movement for commuters from Ghaziabad and Greater Noida West heading toward the airport via NH-9 and the Delhi-Meerut Expressway corridor.

Will property prices in Shahberi and Crossings Republik rise because of this project?

No dedicated study confirms this for this specific project. Real estate voices point to past NCR infrastructure projects, like the Aqua Line and the FNG Road proposal, that shifted buyer interest before construction even finished, as a reasonable precedent.

Where can I track official updates on this project?

GNIDA's public communications and NHAI's project updates are the most reliable channels, since neither authority has issued a dedicated public notice for this project yet.
