Mumbai Metro Line 7A is the planned extension from Andheri (East) to Chhatrapati Shivaji Maharaj International Airport (CSMIA). To check its route, start with the Mumbai Metropolitan Region Development Authority (MMRDA) project and alignment pages; to find out whether a particular property is formally affected, match its village and survey or gat number against the relevant official land notice or record. A route map or influence-zone indication alone does not prove that a plot has been notified or acquired.
This guide separates three questions that are often confused: where the line is planned, whether a property falls within an influence or NOC area, and whether a competent authority has issued a parcel-specific land document. Keeping those questions separate helps prevent a map, press release or depot figure from being mistaken for a legal notice.

Where will Mumbai Metro Line 7A go?
MMRDA describes Line 7A as an extension from Andheri (East) to CSMIA. Its Metro Line 9 and 7A project page presents the two projects together and gives combined figures of 13.581 km and 10 stations. Those are corridor totals for the combined Line 9/7A project page—not Line 7A-only length or station counts.
That distinction matters when you read maps, project summaries or property reports. A document headed “Line 9 and 7A” may include the separate Dahisar–Mira Bhayander corridor as well as the airport extension. Do not divide the combined length or station number, or present either number as the length or station count of Line 7A alone. For Line 7A-specific station information, use the dated MMRDA construction announcement described below.

The airport connection is therefore best understood as an extension of the Andheri (East) side of the metro network toward CSMIA. The official project description establishes those endpoints; it does not, by itself, establish the status of every intermediate parcel, a final opening date or a passenger timetable.
What are the stations on Mumbai Metro Line 7A?
MMRDA identifies two Line 7A stations: Airport Colony Metro Station, which is elevated, and CSMIA Metro Station, which is underground. The authority listed them in its 17 April 2025 tunnel-breakthrough announcement.
The different structures are useful when reading an alignment drawing. “Elevated” describes the Airport Colony station’s construction form, while “underground” describes the CSMIA station. They are not two alternative routes or two different project phases. The announcement is the cited MMRDA source for these two station names; avoid adding stations from the combined Line 9/7A total to a Line 7A-only list.
That announcement reported a 1.6 km underground tunnel breakthrough. A breakthrough is a construction milestone, not confirmation that the line has opened to passengers. Construction progress, testing, safety approvals and passenger service are separate status questions; check MMRDA’s dated status information rather than treating a construction announcement as an opening notice.
How do I check the official Line 7A route?
Use MMRDA’s own project documents and mapping links as the starting point. The detailed project report (DPR) and influence-zone material serve different purposes: the DPR provides project planning information, while the influence-zone page points to alignment material and property-related NOC guidance.
- Open the MMRDA Metro DPR index. On the Metro DPRs page, select “Metro Line 7A & 9 Andheri (E) to CSIA & Dahisar to Mira Bhayander.” This is the official starting point for the detailed project report. Record the title exactly as displayed, because it identifies a combined project entry rather than a Line 7A-only corridor.
- Read the project description before interpreting the drawing. Confirm whether a page is describing Line 7A, Line 9, or both. The combined project page’s 13.581 km and 10-station figures should remain labelled as combined figures in your notes.
- Check the influence-zone and NOC page. Open MMRDA’s Metro Influence Zone for NOC page and follow its Line 7A alignment link. MMRDA says owners and developers can seek an NOC if a property falls partly or fully within a metro influence area.
- Download or save the relevant map and its date. Keep the page title, link and access date with your property file. Online mapping material can be updated, replaced or reorganised, so a saved copy or clear reference makes later comparison possible.
- Compare the map with a precise property location. Identify the village and the exact survey or gat number as well as the address. A broad neighbourhood match is not enough for a parcel decision. Treat a map check as an initial planning reference; it does not replace a current land record, a formal notice or written clarification from the relevant authority.
- Ask for clarification when the boundary is close. If an alignment boundary appears to pass near a plot, or the map and parcel identifiers do not line up, ask the relevant authority to clarify the location rather than inferring the legal effect from the drawing.
An alignment map answers a geometry question: where the planned project is shown. It does not answer whether a particular owner has received a notice, whether compensation proceedings have begun or whether a title is affected. Those questions require parcel-level records.

How do I check whether my property is affected by Metro Line 7A?
For a property-specific answer, verify the parcel identifiers against the relevant official record. An alignment file shows planned project geography; an influence-zone indication may matter for planning or NOC purposes; neither, on its own, establishes that a particular holding has entered land-acquisition proceedings.
- Pin down the parcel. Record the village and the exact survey or gat number shown in the relevant property records. A street address alone may not identify the land parcel precisely enough for a notice search. Preserve spelling and numbering as they appear in the record, including any sub-division reference.
- Gather the map evidence. Note the alignment file or influence-zone page used, its title and date, and the location you compared. If you used a web map, keep a screenshot or downloaded copy that shows the relevant boundary and scale.
- Find the applicable official notice or land record. Match the village and survey/gat number, and check the document date and issuing authority. The publication route can depend on the location and the stage of acquisition; the official material cited here does not establish one complete, current portal covering every Line 7A parcel notice.
- Identify the stated stage. Check whether the document is a preliminary notification, declaration, award or another kind of record. The label matters because the document may describe a different point in the procedure. Look for amendments and later orders as well as the first notice; an earlier document may not be the latest record.
- Check the project reference. Make sure the notice actually refers to the metro work or land purpose you are investigating. A village can contain records for unrelated public projects, and a Line 9/7A project heading may cover more than the airport extension.
- Compare every identifier. Check the survey or gat number, village, boundaries, date and issuing authority together. A similar-looking number or nearby locality is not a reliable match.
- Resolve discrepancies in writing. If parcel numbers, boundaries or dates conflict, ask the competent authority for confirmation and attach the documents you compared. If the plot may be affected or the records remain inconsistent, consider getting advice from a qualified local property professional.
This is a document-checking guide, not a title search or legal determination. The official route and influence-zone sources help locate project information, but the material reviewed for this guide does not provide a comprehensive parcel-level acquisition list or determine the status of any individual property.
Where can I find a land acquisition notice for my survey number?
Begin with the relevant official MMRDA publication and the competent government land-acquisition record for the property’s location. Search or verify using the village and exact survey/gat number, then compare the notice date, issuing authority and acquisition stage. If no matching notice appears in one source, do not treat that absence as proof that no action exists: the applicable publication route may vary by location and stage.
Keep a record of the search itself. Write down which official page or office record you checked, the date you checked it and the identifiers used. This helps distinguish “no matching document found in this search” from a definitive statement that no notice exists. If an authority directs you to another office, retain that direction and ask which record should be treated as current.

MMRDA’s annual report covering achievements in 2023 says 59.79 hectares at Dongri were received for depots serving Lines 7, 7A and 9. That is a named project-land figure, reported by MMRDA in 2024; it is not a parcel-by-parcel notice list and does not show that any other specific plot was acquired. It should be cited only for that stated depot-land context, not as evidence about a reader’s property.

What is the latest reported Line 7A status?
MMRDA’s status page labels its Line 7A progress update “as on 31st August 2026.” Because construction information can change, consult the MMRDA Present Status page for the latest dated entry before making a current claim about progress.
A dated status entry should be reported with its date, not presented as an undated live percentage. Also separate civil work from other milestones. Civil construction, tunnel work, testing, safety approvals and passenger service are different categories, and completion of one does not establish completion of the others.
Keep older milestones in their proper context. MMRDA’s 2024 annual summary, published in 2025, reported 46% civil work completion for Line 7A in its reporting period; that is historical information, not a current completion percentage. The 1.6 km tunnel breakthrough was reported on 17 April 2025 and likewise does not establish the line’s current operational status.
What did the April 2025 tunnel announcement actually say?
The MMRDA release dated 17 April 2025 recorded the 1.6 km underground tunnel breakthrough and identified the two Line 7A stations. It also included statements from senior officials. Dr. Sanjay Mukherjee, IAS, Metropolitan Commissioner, MMRDA, was quoted as saying: “That is why Metro Line 7A was undertaken, and in just a few months, a tunnel over 1.5 km in length has already been completed.”
The same release attributed this statement to Shri Devendra Fadnavis, Chief Minister of Maharashtra: “The CSMT to Airport connection has now become a reality and today, we witnessed a marvellous Tunnel Breakthrough on Metro Line 7A.”
Both quotations belong to the April 2025 milestone event. They are useful as contemporaneous comments about the breakthrough, but they are not independent verification that passenger service had started, that all works were complete or that a particular opening date was guaranteed. When quoting either statement, retain the speaker and event date so readers do not mistake an event comment for a later status update.

How should I interpret the 59.79-hectare Dongri figure?
MMRDA’s report on achievements in 2023, issued in 2024, says that 59.79 hectares at Dongri were received for depots serving Lines 7, 7A and 9. The number is significant because it identifies project land and names the depot purpose. It still does not identify every parcel involved, describe a reader’s title or prove that a separate plot was acquired.
Use the figure as background when explaining the wider project footprint. For an individual property, return to the village and survey/gat number and locate the applicable formal record. Do not infer from proximity to Dongri, a depot reference or the number of hectares that a particular owner has received a notice.
Which source should I rely on for which question?
| Source or document | What it can help establish | What it does not establish by itself |
|---|---|---|
| MMRDA project page | How MMRDA describes the Line 7A project and its relationship to Line 9 | Whether an individual parcel has been notified or acquired |
| DPR and alignment material | Project planning information and the planned route geometry | A parcel-specific acquisition outcome or compensation result |
| Metro Influence Zone for NOC page | Where to find alignment links and property-related NOC guidance | Proof that a plot has entered acquisition proceedings |
| Tunnel-breakthrough release | The 17 April 2025 milestone, 1.6 km tunnel figure, station descriptions and attributed remarks | Current progress, testing completion or passenger opening |
| MMRDA status page | A dated progress entry, including the update labelled as on 31 August 2026 | A permanent forecast or a parcel-level land decision |
| Annual report or summary | Historical figures such as 59.79 hectares for Dongri depot land and 46% civil work completion in the 2024 reporting period | A current percentage, a complete notice index or proof about another plot |
| Parcel-specific official notice or land record | The stated procedure or record for the identified land, subject to its date and stage | A guarantee that no later amendment or order exists unless those are also checked |
For property decisions, use the document that addresses the question being asked: planned route, influence-zone or NOC relevance, or formal parcel-level land procedure. Keep the document date and parcel identifiers with your notes so a later record can be checked against the same plot.
A practical checklist before contacting an authority
- Write the property address exactly as used in your deed, revenue record or other official document.
- Confirm the village and survey or gat number, including any sub-division notation.
- Save the MMRDA project, DPR or influence-zone page you used and note its date.
- Mark whether your question concerns route geometry, NOC or influence-zone status, or land acquisition procedure.
- Search the applicable official notice or land record using the parcel identifiers, not only a neighbourhood name.
- Compare the issuing authority, document date and stated stage with the project reference.
- Check for amendments, later orders or a newer status entry.
- If anything conflicts, request written clarification and provide copies or links to the documents that differ.
This checklist makes the enquiry more precise. It also prevents a common error: asking whether a broad locality is “on the metro route” when the authority needs a survey or gat number to answer a property question.

Common mistakes when checking Line 7A information
- Using combined figures as Line 7A-only facts. The 13.581 km and 10 stations on MMRDA’s project page cover the combined Line 9/7A presentation.
- Adding stations from another corridor. MMRDA’s Line 7A-specific announcement identifies Airport Colony Metro Station and CSMIA Metro Station; do not expand that list with stations not identified for Line 7A in the cited material.
- Treating a tunnel breakthrough as an opening. The 1.6 km breakthrough is a construction milestone dated 17 April 2025.
- Treating an influence-zone map as an acquisition notice. It may signal planning or NOC relevance, but it is not parcel-level proof of notification or acquisition.
- Assuming the Dongri depot figure identifies every affected owner. The 59.79-hectare figure is a project-land statement for depots serving Lines 7, 7A and 9.
- Repeating an old progress percentage as current. The 46% civil-work figure belongs to MMRDA’s 2024 reporting period.
- Stopping at the first document. Notices can have amendments or later orders; check the complete sequence relevant to the parcel.
- Relying on an address alone. A village and survey/gat number provide the more precise identifiers needed for a notice check.
What should a careful route or property note contain?
Keep a short audit trail: the exact MMRDA page or document title, URL, access date, map or notice date, village, survey/gat number and the conclusion you can support. Separate facts from assumptions. For example, “the map shows the planned alignment near the property” is different from “the property has been acquired.” The second statement requires a matching formal record.
If you are comparing two documents, place them side by side and list differences in identifiers, boundaries, dates and issuing authorities. Ask the competent authority to resolve the specific difference. This is more reliable than relying on a coloured line, a news summary or an undated screenshot.

Frequently Asked Questions
What details should I have before asking the authority about a Line 7A property issue?
Have the village and exact survey or gat number ready, along with the property address and the date or copy of any map or notice you are relying on. If two documents disagree, identify both when asking for written clarification so the authority can address the specific discrepancy.
Why might an alignment drawing not match a land notice exactly?
They answer different questions: an alignment drawing depicts project geometry, while a notice or land record identifies a formal procedure and affected land at a particular stage. Compare each document’s date, issuing authority and parcel identifiers, and check for later amendments or orders before drawing a conclusion.
Can I quote MMRDA’s 2024 civil-work figure as the current Line 7A progress?
No. MMRDA’s 46% figure refers to civil work completion in its 2024 reporting period, while its status page carries a later dated update. Attribute the older figure to that reporting period and use the latest dated status entry for a current progress statement.
How many stations does Line 7A have?
MMRDA’s 17 April 2025 announcement identifies two Line 7A stations: Airport Colony Metro Station, elevated, and CSMIA Metro Station, underground. The 10-station figure on MMRDA’s project page is a combined Line 9/7A figure, not a Line 7A-only count.
Does appearing inside the Metro Influence Zone mean my land will be acquired?
No. MMRDA’s influence-zone page provides alignment links and NOC guidance for owners and developers. An influence-zone indication is not, by itself, a parcel-specific acquisition notice. Verify the village and survey or gat number against the applicable official land record.
The Bottom Line
For Line 7A, use MMRDA’s project, DPR and influence-zone pages to understand the planned Andheri (East)–CSMIA connection and its two identified stations. For a property decision, match the village and survey or gat number against the current competent-authority notice or land record, check the document stage and date, and obtain written clarification when records conflict. Neither a route map, an influence-zone indication nor a depot-land figure substitutes for a parcel-specific formal record.
