The Sarjapur Road metro is the line every brochure on this side of Bengaluru mentions, and the one fewest buyers have checked. Officially it’s Phase 3A of Namma Metro, the Red Line, a 37 km route from Hebbal to Sarjapura with 27 stations in the latest published table. As of October 2026 the Sarjapur Road metro has state approval and a revised project report with the Centre. It has no Union Cabinet sanction and no civil construction. This guide covers the route, the stations, where approvals stand, a realistic timeline, and how to test a “metro in 5 minutes” claim before you pay for it.
Key takeaways
- The Sarjapur Road metro is the planned Red Line (Phase 3A), Hebbal to Sarjapura, about 37 km
- The February 2026 revised plan lists 27 stations: 17 elevated, 10 underground. Some sources still say 28
- Karnataka’s cabinet cleared the Sarjapur Road metro on 6 December 2024. Union Cabinet approval was still pending in August 2026, and we found no sanction after that
- Published opening targets run from 2030 to 2038. April 2033 is the date most often cited
- Kodathi Gate was dropped from the station list in 2026. Dommasandra, Carmelaram and Sompura stayed

What the Sarjapur Road Metro Is
When people say “Sarjapur Road metro”, they mean one specific project: the Hebbal–Sarjapura corridor, numbered Phase 3A and given the colour red on Namma Metro’s map. It isn’t part of the Phase 3 package the Union Cabinet approved in August 2024. That package covered two other lines. The Sarjapur line was split out and is going through its own approval.
The city’s 2020 Comprehensive Mobility Plan identified a Carmelaram–Yelahanka line. The state announced the Hebbal–Sarjapur corridor in its March 2022 budget, at an estimated ₹15,000 crore.
The cost has moved a lot since then:
- The first detailed project report, approved by the state cabinet in December 2024, put it at ₹28,405 crore.
- The Centre sent that report back over cost. Consultants Systra revised it.
- The revised report of February 2026 is cited at ₹25,485 crore by some sources and ₹25,999 crore by others.
Length went from 36.58 km to 37.8 km in the revision. Most sources round it to 37 km.
In one line: the Sarjapur Road metro is a planned 37 km Red Line from Hebbal to Sarjapura. It’s approved by Karnataka, not yet by the Centre, and not under construction.
Sarjapur Road Metro Route, Station by Station
The Sarjapur Road metro starts at Hebbal in the north, goes underground through the old city, comes up near Koramangala and then runs elevated along the Outer Ring Road and Sarjapur Road to Sarjapura town. Here’s the station list from the February 2026 revision, as published on Wikipedia’s Red Line page.
| # | Station | Type | Note |
|---|---|---|---|
| 1 | Hebbala | Elevated | Interchange: Blue and Orange Lines |
| 2–4 | Ganganagar, Mekhri Circle, Palace Guttahalli | Elevated / Underground | Ganganagar elevated, rest underground |
| 5–7 | Bengaluru Golf Course, Basaveshwara Circle, KR Circle | Underground | KR Circle: Purple Line interchange |
| 8–11 | Town Hall, Shanthinagara, NIMHANS, Dairy Circle | Underground | Dairy Circle: Pink Line interchange |
| 12–14 | Koramangala II Block, Koramangala III Block, Jakkasandra | Underground / Elevated | The line surfaces here |
| 15–16 | Agara, Ibbaluru | Elevated | Both: Blue Line interchange |
| 17–19 | Bellanduru Gate, Kaikondrahalli, Doddakannelli | Elevated | Outer Ring Road / Sarjapur Road |
| 20 | Carmelaram | Elevated | Interchange with Carmelaram railway station |
| 21–22 | Ambedkar Nagara, Muthanalluru Cross | Elevated | Sarjapur Road |
| 23 | Dommasandra | Elevated | Junction with Varthur–Sarjapur Road |
| 24–25 | Sompura, Kada Agrahara Road | Elevated | Outer stretch |
| 26–27 | Sarjapura, Sarjapura Terminal | Elevated | Terminal added in 2026; depot near Sarjapur |
That’s 27 stations in the table. Several reports, including some written after the revision, still say 28. Wikipedia’s own text gives 11 underground stations while its table shows 10. We’ve used the table.
What changed on the Sarjapur Road metro in 2026
The revision removed two stations: Veterinary College and Kodathi Gate. It added Sarjapura Terminal. Kodathi matters to buyers. Older station lists included Kodathi Gate, and on the current plan that station doesn’t exist. If a brochure still mentions it, the brochure is out of date.
Where the Phase 3A Metro Approvals Stand
Every Namma Metro line needs two governments, and the Sarjapur Road metro is no exception. The Centre holds a 50% equity share in BMRCL, so the Union Cabinet has to sanction each new corridor. Here’s the record so far.
| Date | Step |
|---|---|
| March 2022 | Corridor announced in the Karnataka budget |
| June 2024 | Detailed project report submitted to the state |
| November 2024 | State finance department clears the corridor |
| 6 December 2024 | Karnataka cabinet approves the report and sends it to the Centre |
| Later | Centre returns the report over cost; Systra appointed to revise it |
| February 2026 | Revised report submitted; geotechnical survey contracts awarded for four sections on 13 February |
| August 2026 | Union Cabinet approval still pending, per the latest status we found |
We searched for a Union Cabinet decision in September and October 2026 and found none. If one comes, it’ll be announced through a Press Information Bureau release. That’s the document to look for, not a WhatsApp forward.
Geotechnical surveys are early work. Soil testing isn’t construction. Deccan Herald has reported that the Sarjapur Road metro needs 836 properties across about 161 acres. Acquiring that much land in a built-up city takes time on its own.
The honest status: the Sarjapur Road metro is a planned line with state backing. Until the Union Cabinet signs off and civil contracts are awarded, nobody can give you a reliable opening date.
A Realistic Sarjapur Road Metro Timeline
Here are the dates in circulation for the Sarjapur Road metro:
- December 2030 — a target cited by one metro information site in 2026.
- 2031 — the original opening target.
- April 2033 — the deferred date in Wikipedia’s text.
- 2038 (to be confirmed) — the date in the same page’s infobox.
Judge these against how long Bengaluru metro work actually takes. The Blue Line’s Central Silk Board–KR Puram section started construction in August 2021. In 2026 it was still under construction, with opening dates of March 2027 and December 2027 both published. That’s six years or so for an elevated stretch on the same Outer Ring Road the Red Line will cross.
The Sarjapur Road metro is longer and includes about 10 km of tunnelling under the old city. Say the Centre approves the Sarjapur Road metro in 2027, tenders take a year, and building takes six or seven years. That puts a full opening somewhere around 2034–35. That’s our arithmetic, not an official forecast. The elevated Sarjapur end could open earlier in sections, as the Purple Line did to Whitefield.
How the Sarjapur Road Metro Connects
The value of the Sarjapur Road metro isn’t only in its own stations. It’s in where you can change trains.
- Agara and Ibbaluru — interchanges with the Blue Line (Central Silk Board to KR Puram and on to the airport). For Sarjapur Road residents, this is the airport link.
- Dairy Circle — interchange with the Pink Line, which runs north–south through the city.
- KR Circle — interchange with the Purple Line near Sir M Visvesvaraya station, for MG Road, Majestic and Whitefield.
- Hebbala — interchange with the Blue Line again and the planned Orange Line.
- Carmelaram — interchange with the railway station on the Bengaluru–Hosur line, which suburban rail plans also use.
So the Sarjapur Road metro is less a Sarjapur–Hebbal shuttle than a spine that plugs the southeast into everything else.
Getting Around Before the Sarjapur Road Metro Opens
For at least the next several years, life on Sarjapur Road runs on roads. Here’s what actually works today.
Carmelaram railway station. It’s on the Bengaluru–Hosur railway line. Check the timetable before you count on it, since trains here aren’t as frequent as a metro.
Buses. BMTC buses run along Sarjapur Road and the Outer Ring Road, and they connect to existing Purple Line stations. Check the routes from your own street, since frequency varies a lot.
The Blue Line, when it opens. Once the Silk Board–KR Puram stretch runs, stations at Agara and Ibbaluru put a train within one road trip of Sarjapur Road. For many residents this will matter more, and sooner, than the Sarjapur Road metro.
Driving. Sarjapur Road and the Varthur–Sarjapur Road are both congested at peak hours, and short distances can take a long time. If you’re buying, drive your own commute at 9am on a weekday before you sign anything.

What the Sarjapur Road Metro Means for Homebuyers
Metro lines do change neighbourhoods, and the Sarjapur Road metro will too. Homes within walking distance of a working station tend to rent faster and resell more easily. The catch is the words “working station”.
Here’s how we’d think about it:
Treat it as a bonus, not a reason. If a home works for you on today’s roads, the Sarjapur Road metro is upside. If a home only works once the metro opens, you’re betting your commute on a cabinet decision and a decade of building.
Distance to the station is what counts. A Sarjapur Road metro station “on Sarjapur Road” helps flats within about a kilometre of it. A villa community 4 km down a side road gets a smaller benefit, because you still need a car or an auto to reach the platform.
Construction years are hard years. Once building starts, expect barricades, diversions and dust along the elevated stretch for three to five years.
Much of it is already in the asking rates. Developers have been marketing the Sarjapur Road metro since 2022. Don’t let a sales team charge you a second time for a station that hasn’t been sanctioned.
If you’re looking at villas or plotted communities in this belt, the factors that matter more day to day are water, road access and the builder’s track record. Our checklist for gated community villas in Bangalore covers those.

How to Test a Sarjapur Road Metro Claim
Many brochures here say “metro station 3 minutes away”. One marketing page for a villa project near Gunjur says exactly that about Dommasandra. Dommasandra is on the station list, but the station doesn’t exist yet. Here’s a five-step test.
- Ask which line and which station. “Upcoming metro” with no name is a red flag. The answer should be “Red Line, Dommasandra” or similar.
- Check the station is on the current list. Kodathi Gate was on older lists and isn’t on the 2026 one. Compare the name against the revised plan.
- Ask for the approval status in writing. If the sales team says the line is “sanctioned”, ask for the date of the Union Cabinet decision. As of October 2026, there isn’t one.
- Measure the distance yourself. Stations sit on the main road. Use a map to measure from the project gate to the junction the station is named after, then add the walk inside the community.
- Ask what the time figure assumes. “3 minutes” is usually a drive with no traffic. At 9am on Sarjapur Road, the same trip can take 15 minutes or more.
None of this means the Sarjapur Road metro won’t happen. The Sarjapur Road metro has state money behind it, a revised plan and survey contracts. It means you should pay for the home that exists now and treat the Sarjapur Road metro as a future gain.
FAQs on the Sarjapur Road Metro
Is the Sarjapur Road metro approved?
Partly. Karnataka’s cabinet approved the Hebbal–Sarjapura Red Line on 6 December 2024. A revised plan went to the Centre in February 2026, and Union Cabinet approval was still pending when we checked in October 2026.
When will the Sarjapur Road metro open?
There’s no firm date. Published targets range from December 2030 to 2038, with April 2033 cited most often. Since construction hasn’t started, any date is provisional.
How many stations will the Hebbal–Sarjapur metro have?
The February 2026 revised plan lists 27 stations over about 37 km, 17 elevated and 10 underground. Some reports still say 28.
Is there a metro station at Dommasandra?
One is planned. Dommasandra is station 23 on the Red Line list, elevated. It won’t exist until the line is sanctioned and built.
Is there a metro station at Kodathi?
Not any more. Kodathi Gate was removed from the station list in the February 2026 revision.
Which lines will the Sarjapur Road metro connect to?
The Blue Line at Agara, Ibbaluru and Hebbala, the Pink Line at Dairy Circle, the Purple Line near KR Circle, the planned Orange Line at Hebbala, and the railway at Carmelaram.
Sources we checked (October 2026): Wikipedia’s Red Line, Blue Line and Namma Metro pages; Deccan Herald reporting on approvals and land; a 2026 metro information site (August 2026 status, December 2030 target). Station names and counts follow the February 2026 revision and may change. Our completion estimate of 2034–35 is our own arithmetic, not an official figure.
