The strategic 13.3-km-long road infrastructure project—popularly referred to as the ‘missing link’—connecting Mumbai and Pune is facing yet another likely delay, as officials confirm a new extension may be sought until March next year. The road, expected to significantly reduce travel time between the two cities by at least 30 minutes, has now crossed multiple deadlines, the most recent one being December this year.
According to a senior official from the state’s transport department, the project, which includes Asia’s widest highway tunnel and an ambitious cable-stayed bridge segment, is at an advanced stage but progress has been hindered due to adverse weather. “The early arrival of the monsoon and intense rainfall in the region has impacted the pace of final-stage work,” the official said. “A formal extension request is being examined and a decision will be made soon.” Implemented by the Maharashtra State Road Development Corporation (MSRDC), the missing link is designed to cut down the existing 19.8-km ghat stretch of the Mumbai–Pune Expressway between Khopoli and Sinhgad Institute in Kusgaon to just 13.3 km. This reduction is expected not only to ease travel but also to enhance safety by avoiding the accident-prone Lonavala ghat section. The new alignment includes two mountain tunnels measuring 8.9 km and 1.7 km, along with two major bridges—one of which, at 840 metres, is a cable-stayed structure still under construction.
The cable-stayed bridge is considered the most technically challenging component of the project and is critical to linking the newly carved tunnels. The 650-metre bridge, another part of the project, has already been completed, and the twin tunnels are structurally ready. However, the incomplete 840-metre bridge has become the cause of delay, especially due to the precision required in engineering and safety audits. Officials say the delays stem from both climatic and logistical issues. “The current phase involves tensioning and final joining work, which must be carried out with utmost precision,” an MSRDC official overseeing the project shared. “Unlike typical road-laying, this portion requires specialised equipment, dry weather, and a stable environment, none of which have been available consistently due to heavy rainfall.”
While delays in public infrastructure projects are not new, the economic implications of this hold-up are significant. The missing link is expected to save nearly ₹1 crore worth of fuel per day by cutting down both distance and travel time. Apart from time efficiency, the project aims to reduce vehicular wear and tear and decrease the carbon footprint by providing a smoother, more direct route. Experts also highlight the sustainability potential of this project. The reduction in traffic congestion on the older ghat route is expected to limit engine idling and lower emissions. The tunnels have been designed to include emergency lanes and modern ventilation systems for improved safety and air quality—aligning with broader goals of creating eco-friendly and resilient transport infrastructure.
The MSRDC maintains that the entire link will be operational within eight months once the bridge is complete and all systems are integrated. The current situation is being monitored closely, and officials are evaluating whether additional resources or structural modifications can be introduced to avoid further slippages. From an urban planning perspective, the link is crucial for enhancing regional connectivity between Pune, Maharashtra’s growing economic and educational hub, and Mumbai, the state capital and financial powerhouse. Over the past decade, traffic volumes on the Mumbai–Pune Expressway have risen significantly, especially on weekends and holidays, leading to prolonged travel times and frequent accidents. The missing link has been envisaged as a long-term solution to this bottleneck.
Additionally, the road segment is expected to accommodate future electric vehicle (EV) infrastructure. “The tunnels and bridges have been built to accommodate not just current load capacities but also anticipated changes in vehicle technology and transport patterns,” said a senior engineer from the MSRDC’s technical division. Transport policy experts warn, however, that repeated extensions could compromise public trust and inflate costs. “Infrastructure timelines must be sacrosanct if we are to deliver dependable mobility solutions,” said an urban transport consultant working with the government. “While safety must always come first, there also needs to be tighter monitoring and contingency planning to counter seasonal disruptions.”
Local business owners and frequent commuters have expressed mixed reactions. While many welcome the long-term benefits of the new road, they are concerned about repeated delays. Logistics firms, in particular, have pointed to the cumulative impact of inefficiencies on freight schedules and operating margins. Despite the setbacks, MSRDC officials remain optimistic. “This is one of the most technically advanced road projects in India, and some challenges are inevitable,” said an official. “But we are committed to delivering a world-class link that meets both safety and sustainability standards.”
As the project enters its final stretch, the coming months will be crucial in determining whether this ambitious link can finally bridge the distance—not just between two cities, but between vision and execution. In a state striving for more climate-resilient and efficient infrastructure, how this project concludes may well become a benchmark for future mega mobility corridors.
