Gurugram, April 16 -- The Gurugram Metropolitan Development Authority (GMDA) will construct a four-lane flyover on Garhi road over the Delhi-Rewari railway track, near Dwarka Expressway in Sector 37 D, officials said. The rail overbridge (ROB) is expected to ease movement for over 10,000 families living in Sectors 37C and 37D, and residents on the other side of the Dwarka Expressway, said GMDA officials. Currently, traffic is affected as the crossing remains closed due to trains. A senior GMDA official said, "The project was earlier planned as a two-lane flyover, but, GMDA CEO PC Meena took up the matter with railway authorities, who approved the revised plan for a four-lane flyover and agreed to bear half the cost." Officials said a consultant was already hired to prepare a detailed project report (DPR) for the two-lane flyover and will now revise it for the expanded project, including approach roads. "The consultant estimated the cost for the two-lane flyover at around Rs.55 crore which is now likely to rise to around Rs.100 crore," said the official. According to the authority, the stretch of the flyover will be built under the supervision of the railway department....
