**Executive Summary**
The National Highways Authority of India (NHAI) is developing the New Khambatki Ghat Twin Tube 6-Lane Tunnel on NH-48 to replace a hazardous and congested stretch of the Pune-Satara highway. With 86 percent of the physical work complete, one side of the tunnel is currently open for public trial operations and safety assessments. The project is scheduled for its official inauguration in the first half of 2026, aiming to significantly reduce travel time and improve commuter safety.
**Key Points / Main Content**
**Project Overview and Status**
* The project consists of a six-lane twin tunnel (three lanes in each tube) located on the Mumbai–Pune–Bengaluru corridor.
* The project has reached 86 percent completion.
* One tube is currently operational for testing purposes to allow for safety assessments and public feedback.
* Full inauguration is projected for the first half of 2026.
**Safety and Infrastructure Enhancements**
* Designed with a wider profile than the previous two-lane tunnel to prevent traffic pile-ups during vehicle breakdowns.
* Equipped with modern safety features, including CCTV cameras, reflectors, and improved lighting systems to eliminate darkness.
* Infrastructure includes visible safety guard railings and designated fire extinguisher points.
* Removes the need to navigate the sharp ‘S’ curves and steep terrain of the old 8 km ghat road.
**Operational Benefits**
* Travel time through the stretch has been reduced from 15–20 minutes to approximately 5–10 minutes.
* The tunnel significantly lowers the risk of frequent accidents and long traffic jams.
* Commuters benefit from reduced fuel consumption and lower vehicle maintenance costs due to decreased wear and tear.
**Strategic Importance**
* Acts as a critical link between major cities, including Pune, Satara, Kolhapur, and Belgaum.
* Improves connectivity to major tourist destinations such as Panchgani, Mahabaleshwar, Kas Plateau, and Sajjangad.
**Impact Analysis**
**Commuters and Travelers**
**Impact**
Travelers experience a significant reduction in transit time and physical exhaustion. The wider lanes and modern safety features reduce the stress and danger associated with the previous bottleneck.
**Action Required**
Commuters should utilize the open tube during the trial phase and adhere to safety protocols and speed limits while assessments are ongoing.
**Local Residents (Khandala and Satara)**
**Impact**
Daily life and safety for local residents are improved through better connectivity between nearby towns and the elimination of hazardous driving conditions.
**Action Required**
Inhabitants should transition to using the new tunnel for daily travel to benefit from the safer, well-lit infrastructure.
**Trade and Tourism Sectors**
**Impact**
The corridor becomes more efficient for the movement of goods and tourists, leading to lower logistical costs and more reliable access to pilgrimage and vacation sites.
**Action Required**
Logistics providers and tourism operators should update their travel schedules to reflect the improved efficiency and reduced transit times on the NH-48 stretch.

From Fear to Freedom: The New Khambatki Ghat
Tunnel, A Safer Passage Through the Ghats
Posted On: 27 APR 2026 6:16PM by PIB Delhi
For decades, the Khambatki Ghat stretch on the Pune-Satara highway was known as a test of patience and
courage. Narrow lanes, sharp ‘S’ curves, long traffic jams and frequent accidents made the journey
stressful, especially during weekends and holiday traffic. What should have been a short drive often
stretched into an exhausting wait inside congested tunnels.
Today, that story is changing.
The New Khambatki Ghat Twin Tube 6-Lane Tunnel Project, undertaken by the National Highways
Authority of India (NHAI) on NH-4 (New NH-48), is transforming one of Maharashtra’s most challenging
highway sections into a symbol of modern, people-first infrastructure.
As part of trial operations and safety assessments, one side of the twin tunnel has been opened to the
public for testing purposes, allowing commuters to experience the improved infrastructure firsthand.
With physical progress of the project reaching 86 percent, the tunnel is on track for inauguration in the
first half of 2026.
One commuter, travelling regularly through the ghat, notices the difference the moment he enters the new
tunnel.
“There are more reflectors, better lighting, CCTV cameras, visible safety guard railings and proper fire
extinguisher points. Compared to the old tunnel, this one is much wider and clearly designed with safety
in mind.”
Another regular traveller, moving from Satara to Pune, recalls the daily struggle on the old route.
“Earlier, the old tunnel had only two lanes. Because of that, traffic used to pile up. If a car or truck broke
down, there would be a long jam and a serious risk of accidents. The old tunnel route used to take around
15-20 minutes. Now, because of this new tunnel, it takes just 5–10 minutes.”
What was once a bottleneck has now become one of the fastest and smoothest stretches on the highway.
For two local women from the nearby village, who travel daily between Khandala and Satara, the tunnel
has changed everyday life.
“This new tunnel feels very good and very safe for travelling. In the old tunnel, travel time was longer and
the risk of accidents was much higher. We travel daily, so we are saving a lot of time now. The lighting
inside the tunnel is excellent, which makes it feel safe. Earlier, darkness was a big issue but not anymore.”Why This Tunnel Matters
The existing Khambatki Ghat stretch is a critical link on the Mumbai–Pune–Bengaluru corridor,
connecting major cities like Pune, Satara, Kolhapur and Belgaum, while also serving thousands of tourists
heading to Panchgani, Mahabaleshwar, Kas Plateau, and devotees visiting Sajjangad.
However, the old infrastructure had reached its limits:
• A 0.85 km two-lane tunnel in one direction
• An 8 km ghat road in the opposite direction
• Sharp curves, steep terrain and frequent congestion
• High accident risk and heavy fuel and time losses
The new tunnel addresses all of this at once.
Engineering Safety, Speed and Scale
With the construction of the new six-lane twin tunnel (three lanes in each tube), travel between Pune
and Satara is being revolutionised:
• Travel time reduced
• Accident risk significantly reduced
• Fuel consumption and vehicle maintenance costs will come down
• Reduced vehicle wear and tear
• Better connectivity for local commuters, trade and tourism
A Safer Passage Through the Ghats
The New Khambatki Ghat twin tube tunnel stands as proof that when infrastructure is designed around
human experience, it does more than move vehicles. It removes fear, returns time, saves lives and restores
trust in the journey itself.*****
