If you’ve driven through Saket or Sangam Vihar recently and wondered why there’s suddenly talk of flyovers and underpasses everywhere, here’s the answer: Delhi’s Public Works Department has approved a major elevated corridor project on Mehrauli-Badarpur Road, one of South Delhi’s most congested stretches. Here’s exactly what’s being built, where, and what it means if you live or plan to live nearby.
Key Takeaways
- PWD has engaged Delhi Metro to build a six-lane elevated corridor and underpass on Mehrauli-Badarpur Road for approximately ₹1,471 crore (Public Works Department, Government of NCT of Delhi).
- Phase 1 covers Saket G-Block to Sangam Vihar with a double-decker structure; Phase 2 adds a 2.48 km flyover from Maa Anandmayee Marg to Pul Prahladpur.
- Saket, Ambedkar Nagar, Khanpur, Sangam Vihar, and Pul Prahladpur are all expected to see improved traffic flow once complete.
Why Is This Road Being Rebuilt?
Mehrauli-Badarpur Road has long been one of South Delhi’s chronic bottleneck stretches, carrying heavy local and through-traffic without the capacity to match. Following a Delhi government budget allocation for several integrated traffic corridors, PWD approved the Mehrauli-Badarpur (MB) Road elevated project to add serious new capacity through flyovers and underpasses rather than simply widening the existing carriageway.
Why it matters: unlike a straightforward road-widening project, this is a genuinely large-scale structural fix — PWD has engaged Delhi Metro itself to handle construction of the six-lane elevated corridor and underpass, at a cost of roughly ₹1,471 crore.
What’s Being Built: Phase 1
The first phase creates a double-decker integrated structure between Saket G-Block and Sangam Vihar, comprising:
- A six-lane elevated flyover
- A six-lane underpass at Saket G-Block
- An elevated ramp connecting the BRT corridor to the flyover
- A two-lane underpass linking Mehrauli-Badarpur Road with the BRT corridor
Worth noting: Saket G-Block isn’t just getting a road upgrade this year — it’s also the planned site of a new Delhi Metro Phase IV station on the elevated corridor linking Lajpat Nagar to Saket, meaning this single junction is set to absorb two major infrastructure projects at once. If you’re weighing up Greater Kailash against Saket for your next move, both localities now have significant transit and road upgrades converging around the same 2026–2028 window.
What’s Being Built: Phase 2
The second phase adds a nearly 2.48 km, six-lane elevated flyover running from Maa Anandmayee Marg to Pul Prahladpur, directly benefiting traffic flow through Ambedkar Nagar, Khanpur, and Sangam Vihar in addition to Pul Prahladpur itself.
Other South Delhi Road Projects Worth Knowing About
The Mehrauli-Badarpur corridor is one of several South Delhi road upgrades PWD has in motion right now:
- Andheria Mor underpass – This junction, which feeds traffic toward IGI Airport, Gurugram, and Qutub Minar, has long struggled with chronic gridlock. A proposed underpass aims to deliver a lasting fix beyond the periodic anti-encroachment drives used so far.
- Adchini to Lado Sarai flyover – A 3 km, six-lane elevated corridor from Mother’s International School to the Mehrauli Archaeological Park, designed to relieve pressure on the high-density Aurobindo Marg.
- Savitri flyover – Currently one-way on the Outer Ring Road, this flyover is set to double in capacity, easing pressure on Chittaranjan Park, Nehru Place, and Greater Kailash.
What This Means for Residents Right Now
Expect the usual construction-phase realities near Saket G-Block, Khanpur, and Sangam Vihar over the coming months: lane diversions, temporary barricading, and slower peak-hour movement while foundation and structural work progresses. Renters and buyers currently evaluating Mehrauli or nearby localities should factor in short-term construction noise and traffic disruption, balanced against the genuinely improved long-term connectivity these projects are designed to deliver. For official updates as construction progresses, the Public Works Department’s Delhi government portal remains the authoritative source.
