Shirur–Karjat corridor to reduce stress

Mumbai: The proposed Shirur–Karjat road corridor, being advanced under Maharashtra’s highway expansion programme, is gaining strategic urgency as authorities seek long-term solutions to recurring congestion on the Mumbai–Pune Expressway. The project, being executed by the Maharashtra State Infrastructure Development Corporation (MSIDC), assumed renewed significance following repeated traffic disruptions — including a recent gridlock that lasted over 30 hours, highlighting the need for alternative mobility corridors capable of absorbing diverted traffic during emergencies and peak freight movement.
Senior officials associated with the project emphasise that the new corridor, along with the ongoing Mumbai–Pune Expressway missing-link works, will play a decisive role in stabilising traffic flows across one of the state’s busiest transport arteries. “The Shirur–Karjat road is not merely an additional highway; it is a structural alternative that will allow authorities to divert heavy traffic when the expressway faces disruptions,” a senior official said.
"When integrated with the expressway’s missing-link project, it will significantly reduce bottlenecks in ghat sections and prevent the kind of prolonged chaos witnessed recently," he added.
With an estimated investment of around Rs 12,500 crore — including land acquisition, engineering works and construction — the proposed four-lane greenfield highway is envisioned as a parallel east–west connectivity spine linking Pune district to the Mumbai Metropolitan Region. The alignment is expected to cover roughly 135 kilometres, passing through Shirur, Pabal, Rajgurunagar, Shirwali and interior Pune nodes before reaching Karjat, with onward connectivity planned toward Panvel and the Uran port corridor.
PPP Model
Planning authorities indicate that the project may be executed under a public–private partnership framework such as the Build-Operate-Transfer model, enabling private sector participation while managing the state’s fiscal exposure. The engineering design is expected to include tunnels, major bridges and dedicated bypass stretches to maintain uninterrupted vehicular movement.
Preliminary assessments suggest the construction of around five tunnels along with multiple bridge structures, reflecting the terrain challenges along parts of the alignment.
The corridor’s strategic importance lies in its ability to serve as a major diversion route for freight traffic originating from Marathwada and eastern Maharashtra. Currently, a significant share of such traffic converges on Pune city before entering the Mumbai–Pune Expressway, contributing to urban congestion and increasing pressure on the expressway’s vulnerable ghat sections. By enabling direct movement toward the Mumbai region without routing through densely populated zones, the new road is expected to substantially ease congestion.
Officials note that the project’s synergy with the expressway missing-link — designed to smoothen curves and remove accident-prone bottlenecks — will create a more resilient transport network. “The missing-link will improve safety and travel time on the existing expressway, while the Shirur–Karjat corridor will provide redundancy,” another official explained.
"Together, these projects will ensure that even if one corridor faces disruption due to accidents, landslides or maintenance, traffic can be seamlessly diverted without paralysing regional mobility,” they say.
Logistic Efficiency
Beyond decongestion benefits, the corridor is also expected to enhance logistics efficiency across industrial belts such as Shirur, Chakan and Talegaon. Improved connectivity to ports and logistics hubs in Navi Mumbai and Uran could reduce transit times and fuel costs for manufacturers, strengthening regional supply chains. Infrastructure planners anticipate the emergence of new economic clusters along the route, including logistics parks, warehousing hubs and agro-processing zones, thereby promoting decentralised industrial development beyond Pune’s urban core.
However, implementation challenges remain significant. Land acquisition across large tracts, environmental clearances and financial structuring under a PPP framework are likely to influence project timelines. Cost escalation risks due to inflation in construction materials and engineering complexities in hilly stretches may also impact execution.
Despite these hurdles, transport planners view the Shirur–Karjat corridor as a transformative infrastructure intervention that could reshape mobility patterns across western Maharashtra. By reducing overdependence on the Mumbai–Pune Expressway — a vulnerability exposed during recent extended traffic jams — the project is expected to strengthen network resilience, improve freight efficiency and support balanced economic growth across the Pune–Mumbai industrial corridor.
