For the first time in over two decades, the most dreaded stretch of road in Maharashtra is about to disappear. What takes its place will change how Mumbai and Pune think about the weekend.
It was 11 PM on a Sunday in February 2026 when a gas tanker overturned near the Adoshi tunnel and brought one of India’s busiest expressways to a complete standstill. For 32 hours, thousands of cars sat trapped on the Mumbai-Pune Expressway in the dark. Families with children. People with early Monday meetings. Travellers trying to make it back from a Lonavala weekend. Social media filled with footage of people standing outside their cars on the expressway, cooking instant noodles on portable stoves, waiting.
That incident was not a freak accident. It was the inevitable result of a flaw that engineers had flagged as far back as 1995 – a chronic bottleneck in the Khandala ghat section where two major highways merge into one narrow mountain corridor, turning ten lanes of traffic into six, through hairpin bends, at steep gradients, during rain and landslides. Every monsoon, every long weekend, every Diwali, this 19.8-kilometre stretch between the Khopoli exit and the Sinhgad Institute junction has extracted hours from the lives of every single person who wanted to go to Lonavala, Khandala, or Pune.
That stretch is finally being fixed. The Mumbai-Pune Expressway Missing Link – a ₹6,695 crore infrastructure project by the Maharashtra State Road Development Corporation (MSRDC) is 99% complete as of April 2026 and is targeted to partially open on May 1, 2026 (Maharashtra Day). And for anyone who uses the Mumbai-Pune corridor to reach a weekend destination, the implications are enormous.
What exactly is the Missing Link project?
The Missing Link is a 13.3-kilometre, 8-lane, access-controlled highway corridor built by MSRDC to bypass the Khandala ghat section of the existing expressway. It connects the Khopoli exit to Kusgaon running through the Sahyadri hills via twin tunnels, elevated viaducts, and a cable-stayed bridge instead of winding over them through the current ghat route.
The project has been in construction since March 2019 and represents one of the most technically complex road engineering undertakings India has attempted. The core infrastructure includes two twin tunnels (1.75 km and 8.92 km – the latter being India’s longest road tunnel), two cable-stayed bridges spanning Tiger Valley and the Khandala gorge, and the widening of the existing expressway from six to eight lanes between Khalapur Toll Plaza and the Khopoli exit.
Once open, the new alignment reduces the problem stretch from 19.8 km to 13.3 km cutting overall distance between Mumbai and Pune by approximately 6 km and allows vehicles to travel at speeds up to 120 kmph, versus the 60–80 kmph crawl that currently defines the ghat.
The project is not a new expressway, it is a replacement for the single worst stretch of the existing one. Everything else about your route to Pune, Lonavala, or beyond stays the same. What changes is that the section most likely to trap you for two hours on a Sunday evening no longer exists as a bottleneck.
How much time does it actually save and why does it matter for a weekend trip?
The official figure is 25 to 30 minutes saved on the Mumbai-Pune journey. In isolation, that sounds modest. In context, it is transformative.
The existing ghat section does not merely cost you 30 minutes of travel time. It costs you the confidence to make the trip at all. Ask anyone who has attempted a Sunday evening return from Lonavala during peak monsoon season. The uncertainty of will the ghat be clear? Will there be a rockfall? Has a truck broken down at the hairpin? shapes decisions about whether to travel in the first place. People book shorter stays to avoid Sunday evening traffic. They leave Lonavala at 3 PM instead of 6 PM to beat the queue. They cancel plans entirely when the weather forecast looks bad.
What the Missing Link restores is not just time, it is predictability. The new alignment runs entirely through tunnels and on elevated viaducts, which means landslides cannot close it. The tunnel grade is near-flat, which means heavy vehicles do not slow to a crawl and cause rear-pile-ups. Traffic police estimate that approximately 70% of expressway vehicles, primarily cars and passenger vans will shift to the new alignment from Day 1, relieving the existing ghat simultaneously.
For the monsoon season specifically which is, counterintuitively, the most popular time to visit Lonavala, the impact is greatest. The Western Ghats become a different world between June and September: waterfalls appear on every ridge, Bhushi Dam overflows, and the valley turns a shade of green that photographs cannot fully capture. But monsoon is also when the ghat section historically becomes most dangerous, and often closes. The new tunnel alignment means the expressway’s access to Lonavala is no longer a single point of failure in heavy rain.
The destinations that benefit most and why now is the time to book
The Missing Link terminates at Kusgaon, right at the Lonavala exit. That geography is not incidental — it makes the entire cluster of Western Ghats destinations along this corridor meaningfully more accessible from both Mumbai and Pune. Here are the four destinations that see the most immediate benefit.
The most popular hill station getaway in Maharashtra just became reliably accessible for a Friday evening arrival and a Sunday evening return without the existential dread.
Your new weekend formula: how to plan the perfect SaffronStays getaway now that the ghat isn’t in the way
The opening of the Missing Link does not just change how fast you get to Lonavala; it changes when you go, how long you stay, and how much you enjoy the return journey. Here is the new calculus for planning a SaffronStays weekend in the Sahyadris.
Arrive Friday evening, not Saturday morning
Under the old ghat conditions, a Friday evening departure from Mumbai was a coin toss. You might arrive at 9 PM, you might arrive at midnight. Most people played it safe and drove Saturday morning, losing half their weekend. With the Missing Link, a Friday evening departure from Bandra at 7 PM becomes a predictable 9 PM arrival in Lonavala. That is an extra 14–16 hours of weekend, and it is a significant shift in how private villa stays work. A Saturday morning arrival meant you were already paying for Friday night without using it. No longer.
Extend your monsoon stay with confidence
Historically, the advice for monsoon Lonavala weekends was to leave by Sunday afternoon at 3 PM to beat the ghat backlog. The Missing Link’s weather-independent tunnel alignment changes this entirely. A Sunday evening departure at 6 PM after a long lunch, a last walk to the waterfall, and a leisurely checkout is now a genuine option. For SaffronStays guests, that means a full two-night stay actually delivers two full days, not one and a half.

The engineering marvel behind the drive: what MSRDC actually built
For travellers who appreciate knowing what is beneath and around them, the Missing Link is not just convenient infrastructure, it is a genuinely extraordinary piece of engineering. Here are the numbers that tell that story.
The 8.9 km tunnel was constructed using controlled blasting through the Sahyadri rock, beneath an active lake. The cable-stayed bridge over Tiger Valley with its twin pylons rising 182 metres from the valley floor was built in wind conditions that regularly exceeded 180 kmph at the construction site. These were not planning-room numbers; engineers designing the bridge had to account for cyclonic-level gusts in a valley that acts as a natural wind funnel. The fact that the structure was completed is a genuine engineering achievement, and when you drive across it, you will be crossing one of the tallest road bridges in India.
Practical guide: what you need to know before you drive the Missing Link
Here are the key details for travellers planning their first trip on the new alignment.
When does the Missing Link open?
MSRDC has confirmed May 1, 2026 – Maharashtra Day as the targeted partial inauguration date. As of early April 2026, 99% of civil work is complete and load testing on the cable-stayed bridge is underway. Only light motor vehicles (cars, SUVs, passenger vans) will be permitted initially. Heavy vehicles will be phased in once safety certifications are complete.
How do I access the Missing Link? Where does it start and end?
The Missing Link starts at the Khopoli exit on the Mumbai-Pune Expressway and terminates at Kusgaon, near Lonavala. If you are driving from Mumbai, you will enter the new alignment shortly after the Khopoli exit the signage will direct you. If heading to Lonavala or Khandala, you exit at Kusgaon, which puts you right at the Lonavala entry point.
Is a FASTag required? Will there be separate tolls?
Yes, FASTag is required across the Mumbai-Pune Expressway. The toll structure for the Missing Link section has not been officially confirmed at time of publishing. Check the MSRDC website or the expressway toll authority for updates before your journey. The existing toll plazas on the expressway remain operational.
Are there any rules specific to the tunnel section?
Standard Indian expressway tunnel rules apply: headlights on at all times inside the tunnel, no lane changes in the tunnel (lanes are marked), no stopping except in designated emergency bays, maintain safe following distance. The 8.9 km tunnel will have continuous lighting and emergency signage throughout. No overtaking permitted in the tunnel.
What is the best time of day to drive to Lonavala after the Missing Link opens?
Friday evenings (after 7 PM from Mumbai) and Saturday mornings (before 9 AM) will continue to see higher traffic on the overall expressway, but the ghat bottleneck that made those timings punishing has been removed. For monsoon visits, the tunnel alignment makes rain-day driving significantly safer and more predictable. Sunday evenings which historically have been the worst are now a viable departure window for those staying at private villas in Lonavala.
The road is finally ready. Is your weekend?
For over two decades, the Khandala ghat has been the silent tax on Maharashtra’s most popular weekend corridor. It has eaten hours, caused accidents, forced early departures, and convinced countless travellers to simply stay home on the weekends when the expressway looked too unpredictable to risk. That era is ending.
The Missing Link is not a small upgrade to existing infrastructure. It is a fundamental rethinking of how the Mumbai-Pune corridor connects to the Western Ghats through the hills instead of over them, at 120 kmph instead of 60, in a tunnel engineered to stay open in conditions that regularly closed the ghat. It is, by any measure, one of the most significant improvements to weekend travel accessibility in Maharashtra in a generation.
For SaffronStays guests, this means the hills are closer than they have ever been. Lonavala at 1 hour 30 minutes from Mumbai. Khandala with its tiger valley views, now a reliable evening drive. Pawna Lake’s dark skies accessible without a pre-dawn departure. The Sahyadris in all their monsoon-soaked, waterfall-draped, fort-topped glory are now squarely within reach of a Friday night escape and a leisurely Sunday return.
The villas are ready. The expressway is ready. Book early! The moment the ghat opens to 120 kmph, Lonavala weekends are going to look very different on everyone’s calendar.
