Mumbai-Pune Expressway's 'Missing Link' Inaugurated: Bypassing the Ghat Section to Enhance Safety and Reduce Travel Time

Mumbai, Maharashtra Chief Minister Devendra Fadnavis recently inaugurated the highly anticipated 13.3-km-long 'Missing Link' project on the Mumbai-Pune Expressway. This new stretch is designed to bypass the steep mountain pass section, enhancing road safety and reducing travel distance between Mumbai and Pune.

The inauguration of the project coincided with Maharashtra Foundation Day, adding a significant milestone to the state's development initiatives. CM Fadnavis officially launched the Missing Link at the Khalapur end of the expressway and proceeded to drive a vehicle on the Lonavala-bound carriageway. Deputy Chief Minister Eknath Shinde accompanied him in the vehicle.

The Missing Link project connects Khopoli on the Mumbai side to Kusgaon near Lonavala in Pune district. It is expected to make the expressway fully access-controlled, significantly easing congestion in the ghat section. Developed by the Maharashtra State Road Development Corporation (MSRDC) at a cost of ₹6,700 crore, the project includes two tunnels, two viaducts, and a cable-stayed bridge over Tiger Valley.

The project forms part of a modern 19.16-km corridor, which also involves widening a 5.86-km six-lane section between Khalapur and Khopoli interchange to eight lanes. Officials stated that the Missing Link will reduce the Mumbai-Pune travel distance by approximately 6 km and cut the journey time by 20 to 30 minutes.

Initially, only light motor vehicles and buses will be allowed on the new stretch, while heavy goods vehicles will continue to use the existing ghat route due to safety considerations. Authorities clarified that no toll hike has been proposed in connection with the project, including at the Khalapur toll plaza in Raigad district.

The tunnels were constructed using the New Austrian Tunnelling Method, involving extensive geological studies across varying rock formations in the Sahyadri ranges. Tunnel No. 1 measures 1.58 km, while Tunnel No. 2 is 8.86 km-long. The tunnels are about 23.5 metres wide, making them among the widest road tunnels globally. An application has been submitted for recognition in the Guinness Book of Records.

The 650-metre viaduct features what officials described as India's tallest road cable-stayed bridge, with pylons rising 182 metres and supported by 240 stay cables. The bridge underwent international testing, including wind tunnel, fatigue, and tensile tests. Tunnel No. 2 passes nearly 180 metres below the Lonavala lake level, making excavation and blasting technically challenging.

The route was executed in difficult mountainous terrain marked by heavy rainfall, strong winds, and low visibility. According to the MSRDC, the project is expected to improve road safety by bypassing accident-prone ghat sections and reduce fuel consumption, resulting in estimated daily savings of around ₹1 crore while lowering pollution levels.

The approximately 95-km-long Mumbai-Pune Expressway is India's first access-controlled highway, and this new addition is set to further enhance its efficiency and safety.
