A massive infrastructure upgrade could soon transform one of India’s busiest highways. The Maharashtra government is reviewing a ₹16,000 crore proposal to widen the Pune–Mumbai Expressway from six lanes to ten lanes, with the project currently in its final stage of evaluation. If approved by the state cabinet, the expansion will significantly increase the capacity of the country’s first access-controlled expressway and improve travel between two of Maharashtra’s most important cities.
The Mumbai-Pune Expressway, which stretches roughly 94.5 kilometres, was inaugurated in 2002 and quickly became a critical transportation artery connecting Mumbai’s financial hub with Pune’s thriving technology and education ecosystem. Over the years, rapid urban growth, expanding industrial activity, and rising vehicle ownership have pushed traffic volumes far beyond the highway’s original design capacity.
Today, the corridor carries a heavy mix of passenger vehicles, commercial trucks, intercity buses, and tourist traffic heading toward popular hill destinations like Lonavala and Khandala. During weekends, holidays, and festival seasons, congestion often builds up, slowing travel and increasing accident risks. The proposed widening aims to address these growing challenges by significantly increasing the road’s carrying capacity.
Under the plan, the expressway would be expanded to 10 lanes, making it one of the widest high-speed corridors in the country. The project will also include improvements to road infrastructure, upgraded safety features, and modern traffic management systems designed to handle rising vehicle volumes efficiently.
Officials believe the expansion will reduce travel delays and improve safety across the route. The expressway currently plays a crucial role in connecting industrial clusters in western Maharashtra with the Mumbai Metropolitan Region, and smoother traffic flow could strengthen freight logistics and supply chains across the region.
The corridor is particularly important for economic activity between Mumbai, Pune, and nearby industrial zones such as Pimpri-Chinchwad and Chakan, which host numerous manufacturing plants, logistics hubs, and technology companies. Faster and more reliable connectivity between these centres is expected to support further economic growth.
Another factor driving the need for expansion is the increasing popularity of tourism destinations along the route. Lonavala and the surrounding Western Ghats attract millions of visitors every year, especially during the monsoon and winter seasons. The surge in tourist traffic adds additional pressure on the expressway, often leading to long queues at bottlenecks and toll plazas.
By widening the corridor to ten lanes, authorities hope to create a smoother travel experience for both commuters and tourists. The upgrade could also reduce fuel consumption and vehicle emissions by eliminating long periods of stop-and-go traffic.
The project is currently undergoing final review before being placed before the Maharashtra state cabinet for approval. Once the cabinet gives its nod, the government will move forward with detailed project planning, including engineering designs, environmental assessments, and the tendering process to appoint contractors.
Due to the scale of the project and the importance of the corridor, construction is likely to be implemented in phases. Authorities will aim to keep the expressway operational during the expansion process to minimise disruption to daily commuters and long-distance travellers.
The widening plan is also part of a broader push to strengthen Maharashtra’s transportation infrastructure. The state has been investing heavily in expressways, metro rail networks, and new urban mobility projects to support rapid urbanisation and economic growth.
If approved, the Pune–Mumbai Expressway expansion could become one of the most significant highway upgrades in India, helping future-proof a corridor that remains central to the movement of people, goods, and tourism between two of the country’s most dynamic cities.
