Pune: Maharashtra has initiated planning for a major upgrade of the older Pune–Mumbai highway, with authorities preparing a detailed project report to expand the existing four-lane corridor into a six-lane route. The proposal aims to improve traffic flow, strengthen regional connectivity and address rising transport demand along one of western India’s busiest road links, while raising fresh discussions around long-term toll funding and sustainable infrastructure investment.
The proposed expansion follows the recent capacity enhancement of the Pune–Mumbai Expressway and reflects growing pressure on the parallel national highway, which continues to serve commuters, freight operators and local traffic. Despite the expressway’s wider carriageway, the older corridor remains an essential transport artery connecting towns, industrial clusters and tourism destinations across the Western Ghats. According to officials associated with the planning process, the Pune Mumbai Highway expansion is expected to require an investment of approximately ₹5,000 crore to ₹6,000 crore. The project will include widening the highway to six lanes alongside engineering improvements designed to ease traffic bottlenecks, particularly through the challenging Lonavala and Khandala ghat sections. Alignment corrections and additional connecting roads are also expected to improve vehicle movement and reduce travel delays.
Infrastructure experts note that upgrading the existing highway could improve network resilience by distributing traffic more efficiently between the expressway and the conventional route. This is particularly significant during peak tourism seasons, maintenance closures or emergency diversions, when both corridors play complementary roles in maintaining regional mobility. Authorities are also evaluating a financial model under which project costs would be recovered through toll revenue. As a result, the existing toll collection period, currently approved until 2035, may be extended by another decade or more if the proposal receives statutory approvals. Transport economists observe that while user-funded infrastructure can accelerate project delivery, future toll policies must balance financial sustainability with affordability for frequent commuters and commercial transport operators. Urban planners argue that the Pune Mumbai Highway expansion should also incorporate climate-resilient engineering, improved drainage systems and slope protection measures, given the corridor’s exposure to intense monsoon rainfall and landslide-prone terrain. Strengthening roadside safety infrastructure, pedestrian access in populated settlements and emergency response facilities could further enhance the corridor’s long-term performance.
The highway upgrade is expected to support economic activity by improving freight efficiency between Pune and Mumbai, two of Maharashtra’s largest economic centres. Better connectivity could also benefit logistics, manufacturing, tourism and real estate markets across the wider metropolitan region. Once the detailed project report is completed, the proposal will move through technical assessments, financial evaluation and regulatory approvals before construction timelines are finalised. The project will be closely watched as Maharashtra seeks to modernise transport infrastructure while ensuring safer, more resilient and citizen-focused mobility across one of the state’s most strategically important road corridors.
