Metro’s 14-m Challenge on Ring Rd

Will Build Link Along Raja Garden Flyover With Little Margin On Either Side

New Delhi:It’s an exercise in precision engineering. Delhi Metro, which will run parallel to Ring Road from Mukundpur to Shiv Vihar, will construct a portion of its viaduct through a passage 12-14m in width. This is when the viaduct itself is 10m wide. “This stretch is near the Raja Garden flyover where the Rajouri Garden station will be integrated with the new station. The stations will be connected through a footbridge,” said a senior Delhi Metro Rail Corporation official.


The challenge is to build the viaduct, which will come from Mayapuri and go towards Rajouri Garden, alongside the flyover. “There’s little leeway since a number of commercial establishments lie next to the flyover, and the distance in-between is only 12-14m. We decided to go ahead as the buildings would have had to be demolished otherwise,” said the official.


To accommodate the buildings, DMRC will build its viaduct, keeping a margin of 1-2m on either side. Interestingly, the buildings, which go up to 40-45 feet, will have the viaduct passing around 9m from the ground, which is the height of the rail level. The stretch where the viaduct goes between the flyover and the buildings will be 120m long. “Around 3m has been spared for entry to the shops, while the parking will be shifted under the flyover during construction. The slip road will be closed during this time,” added the Delhi Metro official.


This is not the only station unique to Delhi Metro. The new corridor, line 7 (Mukundpur-Shiv Vihar), will have several stations that serve as pedestrian connections across Ring Road. Paralleling Ring Road, this corridor will travel through congested areas with high traffic volume. In fact, the stretch between Rajouri Garden to Mukundpur will cross four lines of the existing metro network.


The eight stations that will connect Ring Road and surrounding areas include Mukundpur, which will be built at grade; Azadpur, Shalimar Bagh and Netaji Subhash Place, all of which are underground stations; and Shakarpur, Punjabi Bagh, ESI Hospital and Rajouri Garden.


Three of these stations will be for crossover: Azadpur, Netaji Subhash Place and Rajouri Garden. The stations falling in this stretch will have pedestrian linkages, providing accessibility to not only to the stations but also Ring Road, added Delhi Metro officials. These pedestrian linkages include footoverbridges at Azadpur, Netaji Subhash Place and Rajouri Garden.


Connections through existing subways or footbridges, such as those at ESI, Punjabi Bagh and Shakarpur, will also be provided. Added the Delhi Metro official, “Where the infrastructure exists, we will connect the station with it. Where there isn’t any, we will create new links.”
