Delhi Metro's 1st double deck viaduct planned under Phase 4

Delhi Metro Rail Corporation (DMRC) is constructing three double-decker viaducts as part of its Phase 4 expansion to integrate road and metro traffic on key routes. Spanning 65.2 km with 45 stations, Phase 4 includes the Majlis Park-Maujpur, Aerocity-Tughlakabad, and Janakpuri West-RK Ashram Marg corridors. DMRC aims to operationalize this expanded network, delayed by the pandemic, by 2026.
