Quick answer: This guide covers seven project entries from MMRDA, with Metro Lines 4 and 4A counted as one entry. None is open to passengers or traffic as of 14 November 2026. Two touch Navi Mumbai directly: the Eastern Freeway extension, which is planned with ramps near Airoli Junction, and the Kopri to Patni creek bridge between Thane East and Airoli. The rest mainly change travel inside Thane and towards Bhiwandi. Costs and progress come from MMRDA’s project pages unless a source is named.
This is a researched guide and not an official notice. This site is not affiliated with MMRDA. Dates and progress figures change, so check MMRDA before you plan around any of them.

Projects that touch Navi Mumbai directly
Eastern Freeway extension, Chheda Nagar to Anand Nagar
- Route: 13.90 km, six lane (3 + 3) elevated road starting at Anand Nagar near Thane and running past Mulund, Airoli, JVLR, Kanjurmarg, Vikhroli and Ghatkopar to end at Chheda Nagar.
- Airoli ramps: MMRDA lists up and down ramps near Mulund Check Naka, Airoli Junction and Vikhroli Junction, described in relation to southbound traffic. Airoli Junction here is the Eastern Express Highway junction at the Airoli approach. The elevated road does not run through Navi Mumbai. The ramps are a potential road access benefit for people reaching the highway from Airoli, and MMRDA does not say that every directional movement is provided.
- Cost: MMRDA lists Rs 2,682 crore as the project cost. The same page records an authority approval of Rs 3,314.40 crore on 5 March 2024, so both figures appear in coverage.
- Progress: MMRDA’s project page lists utility diversion, working piles, and casting of piers, pier caps and segments as in progress (MMRDA project page). Another MMRDA listing describes earlier stages, so the pages are not in step. No measurement date is shown on either.
- Opening: no opening date is published on MMRDA’s page.
Kopri to Patni creek bridge
This would add a Thane Creek crossing between Kopri in Thane East and Patni in Airoli. MMRDA’s page says it was planned to work with Thane Coastal Road-2 and the Navi Mumbai International Airport connectivity corridor. For the separate CIDCO tender for an elevated road from Thane towards the airport, see our Thane to Navi Mumbai Airport elevated road guide.
- Design: about 1.8 km long. The main creek bridge is a 240 m extradosed cable-stayed design shown as 5 + 5 lanes (10 lanes in total). The carriageway on the viaduct and approaches is a minimum of 2 + 2 lanes (4 lanes), with extra lanes reserved for future connectivity. Do not read this as a continuous 10 lane road.
- Cost: Rs 723.42 crore. The earlier estimate was Rs 333 crore, approved in October 2022, and the revised figure was approved on 16 February 2026.
- Status: the tender notice was published on 7 May 2026. MMRDA says a provisional NOC from the Maharashtra Maritime Board was obtained on 11 March 2024, and that forest clearance, CRZ clearance and High Court permission for cutting mangroves still have to be obtained. It has asked Thane Municipal Corporation for land at Kopri (6.31 ha) and Patni (1.27 ha) and to add the alignment to the Development Plan.
- For commuters: there is no usable new crossing yet. Any future benefit depends on approvals, construction and completion of the connecting roads.
Metro projects in Thane and Bhiwandi
Metro Line 4 and Line 4A
| Status item | Detail |
|---|---|
| Scope | Line 4 runs 32.32 km from Wadala to Kasarvadavali with 30 stations. Line 4A adds 2.668 km with 2 stations from Kasarvadavali to Gaimukh, with a planned interchange at Gaimukh with Metro Line 10 |
| Cost on MMRDA’s pages | Rs 14,549 crore base cost for Line 4 and Rs 949 crore project completion cost for Line 4A, which together make the Rs 15,498 crore figure quoted elsewhere |
| Civil progress, as on 31 August 2026 | Line 4 activities range from 92% to 98% complete, listed in the table below. Line 4A lists most activities at 100%, with RCC beam erection at 0% |
| Trials | MMRDA records that the trial run of Phase 1 of the Green Line (Lines 4 and 4A) was flagged off on 22 September 2025 |
| Passenger opening | No date on MMRDA’s pages. The Free Press Journal reported the state transport minister saying the first phase, Gaimukh to Cadbury Junction, would open in December 2026 (report). Projects Monitor reported on 28 October 2026 that it was likely to open in December (report). Treat this as a target |
| Available today? | No |
| Line 4 activity | Progress as on 31 August 2026 |
|---|---|
| Pier (viaduct and station) | 95% |
| Pier cap erection | 98% |
| U girder erection | 94% |
| I girder erection | 97% |
| Deck slab | 92% |
| L girder erection | 96% |
| T girder erection | 98% |
| RCC beam erection | 97% |
| Portal beam erection | 93% |
These are separate civil activities (Line 4, Line 4A). They do not add up to a percentage of the whole programme, and civil work being well advanced does not mean passengers can ride. Systems, testing and safety certification have to be completed first. This line does not reach Navi Mumbai. It matters if you work along Ghodbunder Road or the Eastern Express Highway in Thane, or travel on to Mulund and Ghatkopar.
Metro Line 5
| Status item | Detail |
|---|---|
| Configuration on MMRDA’s overview page | 24.9 km, 15 stations, shown as fully elevated, from Thane through Bhiwandi to Kalyan. This is the configuration kept on the overview page and not necessarily the current plan |
| Cost on that page | Rs 8,416.51 crore project base cost including taxes and duties. It belongs to the configuration above and is not the cost of any revised or extended programme |
| Civil progress, as on 31 August 2026 | MMRDA’s page lists nine civil activities, from piling through deck slab and station erection, as 100% completed. The page does not say which phase or package they cover |
| Revised scope (reported) | Magicbricks reported on 2 November 2026 a revised programme of about 34.21 km and 19 stations, with an underground stretch between Dhamankar Naka and Temghar, Phase 1 of about 11.90 km from Kapurbawdi to Dhamankar Naka, an estimated cost of about Rs 18,130 crore and an early 2027 target for Phase 1 (report). MMRDA has also published an announcement titled “Extended Metro Line 5 to Strengthen Connectivity Across Thane, Bhiwandi, Kalyan and Ulhasnagar” (MMRDA announcement) |
| Passenger opening | No date on MMRDA’s overview page |
| Available today? | No |
Civil completion is different from systems installation, testing and passenger opening, so these figures do not mean Line 5 is ready to carry passengers (MMRDA Line 5 page). MMRDA’s overview describes Line 5 as meeting Line 4 and the proposed Line 12. Line 12 is now under construction, and our Metro Line 12 guide covers its Amandoot link to Navi Mumbai Metro Line 1.
Roads and bridges in Thane
Thane Coastal Road
- Route: 13.45 km, six lane greenfield road from Kharegaon toll plaza on the old Mumbai Nashik highway at Balkum to Gaimukh, with a 240 m creek bridge and an 8.11 km viaduct through mangrove areas. It is meant to take intercity traffic off Ghodbunder Road.
- Cost and clearances: Rs 3,364.62 crore and a 48 month construction period. MMRDA lists clearance from the state coastal authority in August 2023 and CRZ clearance from the Union environment ministry in March 2025.
- Progress: work began in December 2024. MMRDA’s consolidated project listing shows 41.04% physical progress and 40.24% financial progress. Another MMRDA page shows 37.37% physical and 34.22% financial. Neither shows a measurement date, so the two figures need reconciling and no single figure is given here.
- For Navi Mumbai commuters: if you take Ghodbunder Road towards Gujarat or Nashik, this road is aimed at that traffic. It does not link to Navi Mumbai itself. A further phase, Thane Coastal Road-2, is a separate project.
Anand Nagar to Saket elevated road
MMRDA lists an accepted cost of Rs 1,847.72 crore, with geotechnical investigation, utility identification and test piles complete and pile work in progress. The Eastern Freeway extension is designed to merge with this road at Mulund Octroi Naka, so the two are meant to work as one corridor along the Eastern Express Highway (MMRDA project details). No measurement date is shown.
Gaimukh to Payegaon creek bridge
A 6.509 km link between Gaimukh in Thane and Payegaon on the Anjur Chinchoti road. MMRDA says the trip between those points currently covers about 31.5 km and takes about 1.5 hours by road. Project cost is Rs 975.58 crore excluding GST. MMRDA lists CRZ clearance as obtained, Stage I forest approval granted, land acquisition notified in part, and physical progress of 23% and financial progress of 21%, without a measurement date. The completion period is 42 months. This bridge serves Thane and Bhiwandi and has no stated link to Navi Mumbai.

How this guide was checked
- Costs, lengths, contractor dates, trial milestones and progress figures come from MMRDA’s project pages. The roads page and the metro pages were last updated on 13 November 2026, and the metro progress tables are dated 31 August 2026. A recent page update does not mean the progress figures were newly measured.
- Road progress figures carry no measurement date on MMRDA’s pages, and where two pages differ both figures are shown.
- Opening targets for Metro Line 4 and the revised Line 5 scope come from press reports and are labelled as such. MMRDA does not publish opening dates for any of the entries on its project pages.
- Social media posts that circulate these projects as a list were not used as sources.
- Checked on 14 November 2026.
Frequently Asked Questions
Will the Thane metro lines connect to Navi Mumbai?
Not directly. Lines 4, 4A and 5 run through Thane, Bhiwandi and Kalyan. Metro Line 12, which is under construction, runs from Kalyan to Taloja and is planned to meet Navi Mumbai Metro Line 1 at Amandoot. It is not open yet.
When will Metro Line 4 open?
MMRDA has not published an opening date. The trial run of Phase 1 was flagged off on 22 September 2025. The Free Press Journal reported the state transport minister saying the first phase from Gaimukh to Cadbury Junction would open in December 2026. Treat it as a target.
Is Metro Line 5 finished?
MMRDA’s page lists nine civil activities as 100% completed as on 31 August 2026, but civil completion is not passenger readiness. A revised, longer programme with an underground stretch has also been reported, so check MMRDA for the current scope.
Which Thane project is closest to Airoli?
The Eastern Freeway extension is planned with ramps near Airoli Junction, and the Kopri to Patni creek bridge would land in Airoli. The bridge is still in tender and needs several approvals.
Does the Thane Coastal Road go to Navi Mumbai?
No. MMRDA describes it as running from Kharegaon toll plaza at Balkum to Gaimukh to take through traffic off Ghodbunder Road.
Are any of these projects open?
No. As of 14 November 2026 MMRDA lists all seven entries as under construction or in tender. This answer will change when any phase of any project opens.
