Mumbai: In a bid to find a lasting solution to chronic monsoon flooding at Andheri subway, the BMC has appointed a consultant to carry out a feasibility study for constructing a flyover above it. The consultant has been asked to submit the report within three months.Mogra nullah, which runs close to Andheri subway, has a catchment extending nearly 2.5km from its source to the subway. A gradient of about 13 metres along this stretch causes rainwater to flow swiftly during heavy showers. During high tide, the nullah’s water level rises further, resulting in flooding of the subway and nearby areas such as Azad Nagar. The subway is frequently shut during such episodes, leading to severe traffic snarls.As a permanent remedy, the BMC has prepared a proposal to build a flyover over the subway. The feasibility study will assess whether the flyover can be constructed, its likely length, technical challenges, estimated cost, projected benefits, and issues related to statutory approvals, including permissions from the railway authorities.If the flyover is found to be viable, other proposed measures to address waterlogging at the subway will be shelved. Earlier, the BMC had drawn up a Rs 209-crore plan to install a new stormwater drain to divert excess rainwater from Mogra nullah. However, concerns that the subway could still get inundated even after the work led to the proposal being put on hold.Andheri Subway is a key east–west connector in the western suburbs. Located near Gokhale Bridge and close to Andheri railway station, it passes beneath the railway tracks. Its annual monsoon flooding has a citywide impact on traffic movement.
