Thane-Borivali Tunnel Overview
Thane-Borivali Twin Tunnel will run under Sanjay Gandhi National Park (SGNP), connecting the eastern suburb of Thane with the western suburb of Borivali through twin road tunnels.
It is planned as an 11.8 km long corridor, of which around 10.8 km will be actual tunnel and the rest will be approach roads at both ends.
This Thane-Borivali Twin Tunnel is designed to cut travel time from 60–90 minutes to about 15–20 minutes, reducing traffic on Ghodbunder Road and Western Express Highway.
Start and End Point, Route & Alignment
The Thane-Borivali tunnel starting point on the Thane side is near Tikuji-Ni-Wadi at Manpada / Ghodbunder Road area, a major junction connecting Thane with the rest of Mumbai.
The tunnel’s end point on the western side is at Magathane’s Ekta Nagar, near the Western Express Highway in Borivali, giving direct access to the western suburbs and Mumbai city.
In simple words, the Thane Borivali tunnel start and end point are: Thane (Ghodbunder Road–Manpada–Tikuji-Ni-Wadi side) to Borivali (Magathane–Ekta Nagar–Western Express Highway side).
The Thane-Borivali tunnel alignment passes deep below SGNP at around 20–23 metres underground so that there is minimal impact on the forest and wildlife.
It will have two parallel tunnels, each carrying one-way traffic with three lanes, including an emergency lane and cross passages every 300 metres for safety.
Because of this underground Thane Borivali tunnel alignment, surface roads inside SGNP are not needed, which helps protect the park and also reduces noise and air pollution in the area.
Project Cost, Budget, Contract & Contractor
Different reports mention slightly different numbers for the Thane-Borivali tunnel project cost, but the range is around ₹13,000 crore to ₹16,600 crore depending on scope and year of estimation.
MMRDA documents and multiple infrastructure portals state that the tunnel’s civil work and associated components are commonly quoted around ₹13,200 crore, as part of the planned Thane-Borivali tunnel budget.
Some overviews that include land acquisition, rehabilitation and escalation quote a higher figure of about ₹16,600 crore for the full Thane Borivali tunnel cost package.
The implementing agency for the Thane Borivali tunnel contract is the Mumbai Metropolitan Region Development Authority (MMRDA).
For construction, a joint venture of L&T and Megha Engineering & Infrastructures Ltd (MEIL) initially emerged as the lowest bidder; later, MEIL was finalised as the preferred contractor for both civil packages.
MEIL is handling the tunnelling work using very large Tunnel Boring Machines (TBMs), making it one of the most advanced road tunnel jobs in the country.
Thane Borivali Tunnel Boring Machine & Construction Status
The project will use four mega TBMs to bore the twin tunnels under SGNP; these are supplied by German tunnelling specialist Herrenknecht.
One of these is India’s largest single-shield TBM, with a cutterhead about 13.34 metres in diameter, specially designed for the Thane-Borivali tunnel boring machine needs in mixed rock conditions.
The first TBM cleared its factory acceptance test in early 2025, marking a key step for starting full-scale tunnelling work.
In late 2025, a big milestone was achieved when this massive TBM was lowered into the launch shaft on the Thane side, near Ghodbunder Road.
This event means portal excavation, shaft construction and technical preparations on the Thane side are largely complete, and continuous tunnelling toward Borivali can begin.
Videos shared by MMRDA and news channels show the cutterhead lowering, giving a real Thane Borivali tunnel current status today video update for viewers who want to see progress on ground.
Opening Date, Current Status & Latest News
The foundation stone (Thane Borivali tunnel bhumi pujan) was done by Prime Minister Narendra Modi on 13 July 2024, officially launching the project.
The planned construction period is roughly 4–5 years for the main tunnelling and approach roads, though some newer articles suggest completion between 2028 and 2029 depending on pace.
As of late 2025, the Thane Borivali tunnel current status is: land acquisition and rehabilitation are underway, Thane-side shaft and portal are ready, and the TBM has been lowered, with active tunnelling about to start or just starting.
Because of this, the exact Thane Borivali tunnel opening date is not fixed yet, but the target is to open the link around 2028–2029 if work continues without major delays.
The latest Thane Borivali tunnel news and MMRDA updates highlight that once operational, the drive between Thane and Borivali will drop from 1–2 hours to around 15 minutes.
This shorter route is expected to cut the distance by around 10–12 km, offering a faster, safer and more reliable cross-city connection.
Distance, Route Map, Alternate Routes & Name
The full Thane Borivali tunnel distance including approach roads is around 11.8–11.84 km, with the core bored tunnel length about 10.8 km.
The Thane-Borivali tunnel route map shows the link starting near Tikuji-Ni-Wadi / Manpada junction on Ghodbunder Road, diving under SGNP, and surfacing near Magathane–Ekta Nagar junction on Western Express Highway in Borivali.
Many real estate and infrastructure blogs also share a Thane Borivali Tunnel map pdf style layout, which you can usually find on MMRDA press notes or detailed infra articles for exact alignment and entry–exit locations.
Till the tunnel opens, the main Thane Borivali tunnel alternate routes remain Ghodbunder Road via Mira Road–Dahisar, or Eastern Express Highway plus JVLR/SCLR to reach the western side, all of which are often heavily congested.
Once this Thane Borivali tunnel is ready, most east–west through traffic is expected to shift underground, freeing up surface roads and creating smoother options for local commuters as well.
The official Thane Borivali tunnel name used in documents is usually “Thane–Borivali Twin Tunnel Project”, often also called “Borivali-Thane Underground Tunnel” or “Thane–Borivali Link Road Tunnel” in media.
Conclusion
The Thane-Borivali Tunnel stands as a bold step toward easing Mumbai’s traffic woes while keeping Sanjay Gandhi National Park intact. With the massive TBM now in place and tunnelling set to ramp up, this project could transform daily commutes and boost property values along the route by 2029. Stay tuned to MMRDA updates for the next big breakthroughs on this game-changer.
