The new section takes the total length of the line to 57.2km following the opening of the 17.8km eastern section on October 31, the 8.1km Durgabai Deshmukh South Campus - Lajpat Nagar section in August, and the 21.6km Durgabai Deshmukh South Campus - Lajpat Nagar stretch in March.
A final 1.4km section between Mayur Vihar Pocket 1 and Trilokpur Sanjay Lake, which has been held up due to land acquisition issues, will open later this year. This will complete the Pink Line loop with the line following the route of Delhi’s inner ring road.

Bombardier has installed its Cityflo 650 CBTC on all four phases of the line, which is the only Delhi metro line to interchange with each of the network's six other lines.

The extension takes the total length of the Delhi metro network to 317km with 231 stations.
