DMRC will carry out a feasibility study for an integrated double-decker flyover-cum-metro corridor along the proposed Keshav Puram-Rohini Sector 34 corridor, part of Phase-V(B) expansion. The 16.3-km corridor is one of seven proposed expansions awaiting final approval. If feasible, it will be the city's fourth double-decker flyover, with three currently under construction. On a double-decker viaduct, vehicles run on the lower deck while metro runs on the upper deck.

A tender has been floated for a consultancy service to conduct the study. Estimated cost: Rs 2 crore, expected completion: six months.

The proposed corridor will be fully elevated with 12 stations connecting West Shalimar Bagh, East Pitampura, Rohini Sector 16, Delhi Technological University and Rohini Sector 29. Three stations will have interchange facilities: Keshavpuram (Red Line), North Pitampura (Pink Line) and Rohini Sector 34 (Red Line).

Existing double-decker viaducts under construction:

• Bhajanpura-Yamuna Vihar (Pink Line): 1.4 km, expected operational by year-end
• Azadpur-Ashok Vihar (Magenta Line extension): 2.2 km, expected ready by year-end
• Sangam Vihar-Ambedkar Nagar (Golden Line): 2.4 km, longest of the three

Other DMRC Phase-IV projects under construction: Krishna Park Extension to Deepali Chowk, Inderlok to Indraprastha (Magenta Line extensions), Delhi Aerocity to Tughlaqabad and Saket G Block to Lajpat Nagar (Golden Line), Rithala-Kundli (Red Line extension).
