South Delhi’s next major metro expansion is already under construction — an elevated corridor linking Lajpat Nagar to Saket G-Block, adding a second Greater Kailash station along the way. Here’s the honest, current status of this project and what it means for the localities it passes through.
Key Takeaways
- The Lajpat Nagar-Saket corridor spans 8.385 km, elevated, as part of Delhi Metro’s Phase IV expansion.
- Cabinet approval came in March 2024, with Rail Vikas Nigam Limited awarded the roughly ₹447 crore construction contract in July 2025.
- Completion is targeted for 2028, adding a new elevated Greater Kailash station alongside the existing underground Magenta Line stop.
Project Status: Under Construction, Not Yet Open
Unlike a freshly inaugurated line, this corridor is still mid-construction as of 2026. Cabinet approval was granted in March 2024, and Rail Vikas Nigam Limited (RVNL) was awarded the roughly ₹447 crore contract to build it in July 2025. The target completion window is 2028 — worth treating as an estimate rather than a fixed date, since large infrastructure projects commonly see timelines shift.
Route & Stations
The corridor runs 8.385 km, fully elevated, from Lajpat Nagar to Saket G-Block, with eight stations planned along the way. Confirmed stops include:
- Lajpat Nagar – Interchange with the existing Violet and Pink Lines
- Chirag Delhi – Interchange potential with the existing Magenta Line station
- Greater Kailash (new elevated station) – Built close to the existing underground GK station; see our Greater Kailash area guide for the neighbourhood this serves
- Saket G-Block – Terminus, also the site of a major PWD road project happening at the same time
Why This Corridor Matters
For a locality like Greater Kailash, gaining a second, elevated station adds real redundancy to an already strong two-line position — see our GK area guide for how the existing Magenta Line station already shapes the locality. For Saket, the new terminus arrives at almost the same time and location as a separate, major road project, meaning Saket G-Block is absorbing two significant infrastructure upgrades in the same window.
What This Means for Renters and Buyers
Anticipated connectivity upgrades like this tend to get priced into resale and rental value well before the line actually opens. If you’re evaluating Lajpat Nagar, Greater Kailash, or Saket with a multi-year horizon, this corridor is a genuine, funded, contracted project — not a speculative announcement — which makes it a reasonably safe factor to weigh into a long-term decision.
