Chennai Metro Corridor 5 Hits a Precast Milestone: A Buyer's Checklist for the Southern Stretch
On October 13, 2026, Chennai Metro Rail Limited said the Ullagaram to Sholinganallur package of Phase 2 Corridor 5 had completed all 3,126 precast elements, including the final U-girder. This guide explains what the milestone covers, what CMRL's own pages say about Phase 2 timelines, and what Chennai buyers near the corridor should verify before booking.
On October 13, 2026, Chennai Metro Rail Limited (CMRL) put out a short press release with a long list of numbers. On the Ullagaram to Sholinganallur package of Phase 2 Corridor 5, the casting yard had poured the last U-girder. In all, 3,126 precast elements had been cast for that package: 1,041 I-girders, 892 U-girders, 871 pier arm segments, 303 pier caps and 19 portal shells. CMRL said that was the highest U-girder output among the Phase 2 packages.
For anyone looking at a flat along the southern stretch of the corridor, that release is worth reading closely, for what it says and for what it leaves out. This guide sets out the milestone, places it against CMRL's own Phase 2 timeline, and lists the checks a buyer can run before paying a booking amount. It is buyer guidance, not a forecast of prices or a suggestion to buy near any station.
The short answer. CMRL's October 13, 2026 press release says the Corridor 5 package ECV-03, Ullagaram to Sholinganallur, has completed 100 percent of its 3,126 precast elements, and that work now moves to erecting the remaining U-girders and building station entry and exit structures. CMRL's project status page, last updated November 26, 2025, describes Corridor 5 as 47.0 km from Madhavaram to Sholinganallur and says Phase 2 is proposed to be completed by the end of 2028. The trade-off: a visible construction milestone lowers execution uncertainty for this package, but it is not an opening date, and a seller's brochure promising one should be checked against CMRL's own word.
What exactly did CMRL say was completed?
The precast work for one package. The release names the package as Phase 2 Corridor 5 ECV-03, running from Ullagaram to Sholinganallur, executed by CMRL with the general consultant AEON Consortium and the contractor HCC-KEC Consortium. It reports the successful completion of the final U-girder casting and 100 percent completion of all precast elements.
The quantities are specific. Beyond the 3,126 elements, CMRL said the precast works used 98,052 cubic metres of concrete, 18,550 tonnes of reinforcement steel and 3,010 tonnes of high tensile strands. Precast elements are cast in a yard and then lifted into place, so finishing the casting is a step before, not the same as, finishing the viaduct.
The release is explicit about what comes next. With the final U-girder cast, it says, the project now advances towards the erection of the remaining U-girders and the construction of entry and exit structures. In other words, some girders are still to be placed, and stations still need the structures commuters use to get in and out.
Where does Corridor 5 sit in Phase 2?
It is the longest of the three Phase 2 corridors. CMRL's project status page says Phase 2 has been planned as a 118.9 km network with 128 stations, made up of Corridor 3 from Madhavaram to SIPCOT (45.8 km), Corridor 4 from Lighthouse to Poonamallee Bypass (26.1 km) and Corridor 5 from Madhavaram to Sholinganallur (47.0 km).
The same page puts the estimated cost at Rs 63,246 crore including IDC (interest during construction), says the proposal is approved by the Ministry of Housing and Urban Affairs, and says the project is proposed to be completed by the end of 2028. Note the page's own date: it was last updated on November 26, 2025, so treat the timeline as CMRL's stated plan at that point rather than a fresh commitment.
What does the milestone change for a buyer, and what does it not?
It changes your evidence, not your certainty. Before a milestone like this, a buyer weighing a home near the southern end of Corridor 5 had only plans and promises. Now there is an official record that one package's precast work is done. That is a fact you can cite when a seller or broker makes claims about progress.
What it does not give you is a date. The press release names no commissioning or opening date for Corridor 5 or for this package. If a brochure, listing or sales pitch gives a specific month for trains near a project, ask where that date comes from, and compare it with CMRL's own pages. Construction milestones are encouraging, but the opening of a metro section also depends on work that remains after girders are erected, including station structures.
The table below separates what CMRL has stated from what a buyer should do with it.
| Item | What CMRL says | Source date | What a buyer should do |
|---|---|---|---|
| Corridor 5 ECV-03 precast work | 3,126 elements cast, 100 percent complete, final U-girder done | October 13, 2026 | Treat as progress on one package, not the whole corridor |
| Next steps on ECV-03 | Erection of remaining U-girders, entry and exit structures | October 13, 2026 | Ask any seller citing an opening date for its source |
| Corridor 5 route | Madhavaram to Sholinganallur, 47.0 km | Page updated November 26, 2025 | Map your project's distance to the alignment yourself |
| Phase 2 completion | Proposed by end of 2028 | Page updated November 26, 2025 | Plan your commute without the metro until it opens |
| Corridor 4 service | Poonamallee Bypass to Vadapalani, 11 stations, about 15 km, open from October 11, 2026 | October 10 and 21, 2026 | Use it as a reference for how CMRL announces openings |
How did CMRL announce the last Phase 2 opening?
Through a dated press release with a start date, station list and timetable. On October 10, 2026, CMRL announced regular passenger services on Corridor 4 from October 11, 2026, covering 11 elevated stations over about 15 km from Poonamallee Bypass to Vadapalani: Poonamallee Bypass, Poonamallee Bus Stand, Poonamallee Government Hospital, Karayanchavadi, Kumananchavadi, Kattupakkam, Iyappanthangal, Thelliyaragaram, Porur Bypass, Porur Junction and Vadapalani.
A further release on October 21, 2026 said that, based on commuter feedback, services would start at 6 am from October 23, 2026 and run until 9 pm, with trains every 10 minutes in weekday peaks of 8 am to 11 am and 5 pm to 8 pm, and every 15 minutes at other times and on Sundays and holidays.
CMRL also publishes ridership. Its October 1, 2026 press release said 1,00,26,601 passengers travelled on its trains between September 1 and September 30, 2026, with the highest single day flow of 3,93,580 passengers on September 11. It added that it offers a 20 percent discount on ticketing services such as the NCMC card and digital QR tickets. For a buyer, those figures are a reminder that the network is in heavy daily use where it runs, and that fares and discounts belong in a realistic monthly commute budget once a line near your home actually opens.
The opening announcements set a useful pattern. When a Corridor 5 stretch opens, expect a similar official notice. Until you can point to one, a home's metro access is a future possibility, not a present feature, and your budget and commute plan should work without it.
What should a Chennai buyer near the corridor check before booking?
Start with distances and documents, then pricing. Proximity to an alignment can matter for daily life, but construction can also bring long periods of road diversions, and CMRL publishes an Influence Zone NOC policy on its website for building activity near its structures. Our earlier explainer on CMRL's protection zone and NOC rules covers the building side.
- Open CMRL's Phase 2 route map and mark your shortlisted project's location against the Corridor 5 alignment.
- Measure the walking or road distance to the nearest planned station yourself rather than relying on a brochure.
- Ask the builder or seller for the source of any metro date they quote, and compare it with CMRL's press releases.
- Check CMRL's road diversion page for your stretch, since construction traffic can affect access for years.
- Ask whether the project needed any metro related clearance and request a copy if it did.
- Confirm the project's own approvals and possession date independently of any metro claim.
- Work out your commute and running costs as if the metro were not yet open, and treat any future access as a bonus.
This approach keeps the decision grounded in what exists today. A home that works for your family without the metro will still work if the line opens on time, and will not become a burden if it opens later than a seller suggested.
Is this the first Corridor 5 milestone PropNewz has covered?
No. We reported on U-girder progress on Corridor 5 earlier this year in our story on Corridor 5 U-girder work. The October 13 release moves that story forward for the Ullagaram to Sholinganallur package: all casting is now done, and the remaining steps are erection and station structures.
We will keep tracking CMRL's own releases rather than secondary reports. If you are comparing homes along the corridor, keep a simple log of each milestone with its date and source. Over a year or two, that log will tell you more about real progress than any marketing material.
