Pune, 22nd June 2023: The journey between Mumbai and Pune is set to become more comfortable for lakhs of commuters as the Maharashtra State Road Development Corporation (MSRDC) undertakes the construction of a new 19.80 km lane on the Mumbai-Pune highway, featuring the world’s largest tunnel.
This ambitious project aims to significantly reduce travel time, with over 50 percent of the tunnel construction already completed. Passengers can expect the tunnel to open by July 2024.
The project involves the construction of two tunnels, measuring 1.75 km and 8.93 km in length, respectively. These tunnels will rank among the longest in India and will surpass all others in Asia in terms of width. With a width of 23 meters, both tunnels will become the widest in Asia, featuring a total of four lanes.
Upon the completion of these tunnels, the distance between Mumbai and Pune on the Expressway will be shortened by six kilometers. The stretch between Khopoli and Sinhagad Institute (Lonavala) on the Expressway will be reduced from 19 km to 13.3 km, saving commuters approximately half an hour on their Mumbai-Pune journey.
To connect the tunnel with the Expressway, a cable-stayed bridge is being constructed, with its massive pillars nearing completion. Currently, the old Mumbai-Pune highway and the Expressway have two and four lanes running together. However, the stretch from Adoshi Tunnel to Khandala on the Expressway experiences the highest traffic. The completion of the tunnel will provide much-needed relief from congestion in this area. Additionally, the project aims to mitigate accidents caused by landslides in the region.
The construction of these expansive tunnels signifies a remarkable milestone in the development of infrastructure in the Mumbai-Pune corridor. As the widest tunnels in Asia, they will enhance connectivity and pave the way for more efficient travel between the two cities. Commuters can look forward to a smoother and safer journey, saving valuable time and reducing the impact of traffic congestion.
