The detailed project report (DPR) of the much delayed Metro extension between Palam Vihar in Gurugram and Sector 21 in Dwarka has been approved by the Haryana cabinet. According to the media reports, the extension project is likely to cost Rs 1,851 crore, out of which the State Government will bear around Rs 1,541 crore worth of the expenses whereas,the rest would be divided with the Central Government. The metro extension connecting Rezangla Chowk in Palam Vihar and Dwarka Sector 21 station will be 8.4km long, of which 5km will be in Gurugram — from Palam Vihar to Sector 111 – and the remaining 3.4km in Delhi. It will have seven stations and has an interchange proposed at Rezang La Chowk in Palam Vihar to allow connectivity with the main Gurugram Metro line, proposed from Huda City Centre to Cyber City via Old Gurugram and Palam Vihar. This project is also likely to result in a reduction in buses, intermediate public transport, usage of private vehicles and air pollution.
