A long tunnel connects the Indian prime minister's residence to Safdarjung Airport, where VVIP helicopters land. Constructed beyond Kemal Atatürk Marg, Golf Course and Safdarjung Tomb and then an overground drive to surface at the helicopter hangar at the airport, work on the tunnel began in 2010 and was completed by July 2014 and Modi was the first PM to use it.
