Before this, the basic infrastructure committee of the state government had approved the process for the implementation of the project. The mega project will decongest roads by diverting traffic that passes through Pune en route to other areas in the state. The existing roads in the city cannot be widened due to the dense urban area and the air as well as sound pollution has crossed its higher limits. The interstate and local traffic flow are high in the city as three major national highways, Mumbai-Bangalore, Mumbai-Hyderabad-Vijayawada and Pune-Nashik, and new national highways, Pune-Pandharpur, Pune-Aurangabad and Pune-Mangaon, crisscross the city.
