Pune is on the brink of a significant urban planning opportunity with the Khadakwasla-Phursungi underground tunnel project, which aims to replace sections of the Mutha Right Bank Canal. This project will not only improve water infrastructure by reducing loss through seepage but also free up valuable land for public use. The Pune Municipal Corporation (PMC) is keen to transform the 33-km canal corridor into a green mobility corridor, addressing the city's pressing need for continuous non-motorized transport infrastructure. The corridor's strategic location makes it an attractive real estate prospect, raising concerns about potential encroachments if left unmonitored. Historical patterns show that unregulated land often leads to unauthorized occupations, making it crucial for the PMC to act quickly. A well-planned corridor could provide safer mobility options, enhance connectivity, and create much-needed public spaces. The city administration must develop a comprehensive plan now to ensure that this corridor serves the public interest and avoids the pitfalls of fragmented urban development.
