The Supreme Court on Monday refused to halt construction work on the phase-IV of Delhi Metro, saying any interference would result in huge escalation of costs. The phase-IV of Delhi Metro will consist of six corridors — Aerocity to Tughlakabad, Inderlok to Indraprastha, Lajpat Nagar to Saket G Block, Mukundpur to Maujpur, Janakpuri West to R K Ashram, and Rithala to Bawana and Narela.
