Spread across 8.385 km, the line will be entirely elevated and will have eight stations. The second corridor, which is an extension of the Green Line, from Inderlok in Northwest Delhi to Indraprastha will be 12.377-km long and will include 10 stations (one elevated and nine underground), the Chief Minister’s Office highlighted in a statement.The third and longest of all three corridors will connect Rithala in Northwest Delhi to Kundli in neighbouring Haryana. The 26.463-km corridor, which is an extension of the Red Line, will have 21 stations and is expected to significantly improve connectivity to Rohini, Bawana and Narela, as well as industrial and residential pockets along the Capital’s northern edge.The corridors — spread across nearly 47 km and estimated to cost Rs 14,630.80 crore — are expected to be completed within four years, the statement underlined, adding that “efficient metro operations will also play a significant role in controlling pollution”.Officials said the three corridors will serve a wide range of neighbourhoods. The Lajpat Nagar–Saket line will pass through areas such as Andrews Ganj, Greater Kailash-I, Chirag Delhi, Pushp Bhawan and Saket District Centre. The Inderlok–Indraprastha corridor will connect central parts of the city, including Dayabasti, Sarai Rohilla, Jhandewalan, Nabi Karim, New Delhi Railway Station, Delhi Gate and the Delhi Secretariat–IG Stadium area.Delhi and its surrounding areas have an existing metro network spanning 395 km with an average daily ridership of around 40 lakh. The Delhi Metro’s existing network is being expanded by 110 km under Phase IV and 96 km and under Phases V-A and V-B. With the completion of Phase IV, daily ridership is expected to double.The government said that the tendering process for the corridors is currently underway, and preliminary work has already begun on some stretches.Story continues below this adThe Inderlok to Indraprastha corridor has been included under a combined financial framework with the Lajpat Nagar- Saket G-Block corridor with a combined project cost of ₹8,399.81 crore, the CMO stated.
