Public Works Department officials said the work is scheduled for completion within two years of the contract being awarded. The existing drainage network has struggled to handle rainwater flowing into the corridor from the Sangam Vihar area, while construction activity has affected natural drainage channels and worsened water accumulation during the monsoon.
Under the approved plan, old brick drains will be replaced with precast reinforced cement concrete box drains. The new structures are intended to increase stormwater-carrying capacity and reduce the frequency of repairs and maintenance along the busy road corridor.
The intervention follows repeated drainage failures on the route. The section between Shooting Range and MB Road, which was reconstructed before the 2026 monsoon, sustained damage after rainwater remained on its surface, highlighting the connection between road construction and drainage performance. A newly rebuilt carriageway remains vulnerable when runoff does not have a reliable route away from the road.
The corridor serves areas where rapid construction and settlement growth have placed additional pressure on older infrastructure. The project is part of the Delhi government’s wider drainage master plan, estimated to cost about Rs. 570 bn, although details on the tendering agency, contractor, package structure and precise drain locations have not been provided. The next formal milestone is the award of work, after which the two-year completion period will begin.
