L&T secures contract to build 15.1 km elevated viaduct and 10 stations
Larsen & Toubro (L&T) will design and construct a 15.1-kilometer elevated viaduct and 10 elevated stations as part of the Noida Metro Aqua Line extensions. The company’s heavy civil infrastructure unit received the order from Noida Metro Rail Corporation (NMRC) and expects to complete the work within 36 months. L&T announced the award to the stock exchange on 9 November 2026.
What exactly is in L&T’s scope of work?
L&T will deliver civil construction works that include detailed design for specific structural elements, architectural finishes for elevated stations and the elevated viaduct itself. Work covers foundations, piers, pier caps, precast and cast-in-place deck segments, station platforms and architectural cladding as defined in contract documents. The company did not disclose the final contract value; NMRC’s tender estimated the project cost at INR 1,267 crore and NMRC classifies the order within the “Significant” band (INR 1,000–2,500 crore).
How the two extension packages break down
The awarded scope comprises two distinct Aqua Line extension sections. The first section runs from Botanical Garden to Noida Sector-142 (11.56 km, eight elevated stations). The second section spans Depot Station to Boraki (2.60 km, two elevated stations). Combined, these deliver the 15.1 km of elevated viaduct L&T will build. NMRC’s project documents list station-level layouts, interchanges and right-of-way alignments for each segment.
Key stations, interchanges and connectivity
Botanical Garden station will provide interchange with Delhi Metro’s Blue and Magenta lines, increasing multimodal connectivity in Noida. The Botanical Garden–Sector 142 corridor will include stations at Noida Sector-44, Noida Office, Sector-97, Sector-105, Sector-108, Sector-93 and Panchsheel Balak Middle School, in addition to Sector-142 itself. The Depot Station–Boraki extension plans transfer access to Indian Railways services and both intercity and local bus terminals, creating a major multimodal transport node at Boraki.
Why this extension matters for the metro network
When Botanical Garden–Sector 142 becomes operational, the active metro network across Noida and Greater Noida will expand to 61.62 km. NMRC’s project summary lists an estimated initial daily ridership of about 80,000 passengers for the Botanical Garden–Sector 142 corridor and an investment outlay of INR 2,254.35 crore in the project report. The Depot Station–Boraki leg specifically aims to knit the metro into a multimodal transport hub, improving first- and last-mile connectivity for commuters using rail and bus services.
Construction details and timeline considerations
The contract specifies engineering, procurement and construction tasks to be executed over a 36-month period. Typical high-level construction steps for elevated metro viaducts and stations are applicable and will guide execution:
Step 1: Mobilization, site clearance and utility diversion to free the corridor and establish temporary works.
Step 2: Foundation works for piers—bore piling or pile cap construction where soil conditions require, followed by curing and testing.
Step 3: Pier construction and erection of precast elements or cast-in-situ pier caps.
Step 4: Installation of deck segments (precast launch or balanced cantilever methods depending on span geometry) and progressive post-tensioning.
Step 5: Station box construction: platform decks, staircases, escalator and elevator shafts, architectural façade works and roof structures.
Step 6: Track slab, drainage, electrical conduits and safety systems integration, followed by systems interfaces with NMRC for signaling, track laying and commissioning.
Route table and scope inclusion
The following summarises NMRC route data and whether L&T’s contract covers each corridor:
Botanical Garden – Noida Sector-142: 11.56 km, 8 stations — Included in L&T scope.
Depot Station – Boraki: 2.60 km, 2 stations — Included in L&T scope.
Sector-51 – Knowledge Park V: 17.435 km, 11 stations — Not part of the L&T order; this is a separate project.
Project approvals, cost and ridership estimates
Uttar Pradesh state cabinet approved the Botanical Garden–Sector 142 extension in June 2024. NMRC’s summary flags an estimated project investment of INR 2,254.35 crore for that corridor and anticipates an opening-day to early-operation daily ridership around 80,000 passengers. The contract awarded to L&T sits in the “Significant” financial band defined by the company and aligns with NMRC’s earlier estimated cost envelope for the two included packages.
Knowledge Park V extension handled separately
The planned Sector-51 to Knowledge Park V extension (17.435 km with 11 elevated stations and an interchange with Delhi Metro’s Blue Line at Sector-61) remains a distinct project and is not part of L&T’s current award. NMRC will advance the Knowledge Park V corridor as a separate procurement and construction package to preserve phasing and funding flexibility.
