The Delhi High Court dismissed a petition seeking to scrap Metro's elevated corridor project in south Delhi on the ground that it would cause noise pollution in residential areas on Friday. A Bench headed by Justice T S Thakur, however, directed the Centre and Delhi Metro Rail Corporation(DMRC) to make all possible efforts to reduce the level of noise pollution which will be caused by the Metro rail running on the elevated corridor. The petition, filed by residents of south Delhi colonius falling on the route of the project, had contended that running Metro rail on elevated corridor would create noise pollution and would interfere in their private life as it would be passing very close to their homes. The elevated corridor of 4/5 km is being constructed between Jawaharlal Nehru stadium and Kalkaji and would pass through Jangpura, Kailash Colony, Defence Colony, Lajpat Nagar and Greater Kailash. The Centre had defended the elevated project, saying a huge investment would be required for building an underground Metro corridor. DMRC had also contended that contract for the project had already been awarded to the companies and it would not been possible to revert back. The court in an earlier hearing had questioned the rationality behind building an elevated corridor for Metro instead of making it underground.
