The stasis that Pune has witnessed on the infrastructure front since the Mumbai-Pune Expressway was made operational in 2002 may be coming to an end, what with investments of Rs 65,000 crore lined up over the next five to six years on the construction of a new airport, a new Metro link, and a Ring Road, among other projects. Taken together with the Rs10,000 crore that has been committed for water, sewerage and Smart City projects, they have the potential to upgrade Pune’s infrastructure to the next level.Work on a Detailed Project Report (DPR) for the Rs 0,000-crore Chhatrapati Sambhaji Raje International Airport at Purandar would start after a nod from the Centre. The Maharashtra Airport Development Company (MADC) would develop the airport on a PPP basis — Singapore’s Changi Airport Group is reported to have evinced interest in the project.
