Gurugram, Sept. 18 -- The Haryana government has asked the Union housing and urban affairs ministry to consider building Phase 2 of the Gurugram Metro as an underground corridor instead of an elevated one, citing severe congestion and multiple bottlenecks along the proposed alignment from Sector 9 to Cyber Hub, officials said. The state's urban local bodies minister, Rao Narbir Singh, in a letter dated September 16 to Union housing and urban affairs minister Manohar Lal Khattar, urged that the alignment be taken underground from Sector 9 through Sectors 4 and 5, Palam Vihar, Sector 23 and finally to Cyber Hub.When asked about the development, D Thara, chairperson, Gurugram Metro Rail Limited (GMRL) and under secretary, ministry of housing and urban affairs said that she will check into the issue. The 16-kilometre-long Phase 2 of the Gurugram Metro will have 14 stations and connect major residential and commercial areas of the city. The line will pass primarily along the central verge of Neki Ram Marg, heading towards Sectors 4 and 5 and Palam Vihar. Officials of both the Gurugram Metropolitan Development Authority (GMDA) and GMRL admitted that constructing Phase 2 as elevated infrastructure will be an issue citing dense traffic flow, markets, and colonies along the alignment. In his letter, Singh wrote, "The tender for Phase-2 is currently being prepared. However, upon a review of the alignment, we would like to request that the second portion of the metro line, which extends from Sector-9 to Cyber City, be considered for conversion to an underground alignment due to the high population density, traffic bottlenecks, number of trees, and 30 metres of road width. The alterations will contribute to the preservation of the metro network's long-term efficacy, enhance safety, and reduce disruption/tree cutting." The GMRL, executing the Gurugram Metro project, has already secured approval from the state and central governments for an elevated metro project from Millennium City Centre to Cyber Hub. This corridor, spanning around 29 kilometres, will cover much of Old Gurugram....
