New Delhi: The 25.6 km-long Janakpuri West-Kalkaji Mandir stretch of the Delhi Metro's Magenta Line is all set to be inaugurated next week, officials said today.

Once opened, it will take the total length of the Delhi Metro Rail Corporation (DMRC) network to 278 km, they said.

Passenger services on the segment, which has 16 stations, will begin on May 29 at 6 am from the Kalkaji Mandir and Janakpuri West stations simultaneously.

Union Minister for Housing and Urban Affairs (Independent Charge) Hardeep Singh Puri and Delhi Chief Minister Arvind Kejriwal will officially inaugurate the corridor on May 28 at 4.30 pm at the Nehru Enclave metro station, a senior DMRC official said.

The dignitaries will travel to Hauz Khas station after the inauguration.

This section will be the longest stretch to have been opened so far in Delhi Metro Rail Corporation's (DMRC's) Phase-III project.

With the opening of this stretch, the entire 38.2 km-long Janakpuri West Botanical Garden Magenta Line corridor, covering the city's arterial Outer Ring Road, will become operational.

On December 25, Prime Minister Narendra Modi had inaugurated the over 12-km-long stretch of the Magenta Line's Botanical Garden-Kalkaji Mandir corridor.
