Western Railway is planning to rebuild the Bandra–Khar Road rail flyover in a single accelerated window of about 45 days, aiming to shorten an earlier proposal for a 90-day shutdown. The reconstruction is part of the Mumbai Central–Borivali sixth railway line project under the Mumbai Urban Transport Project (MUTP) Phase-II, implemented by Western Railway with Mumbai Railway Vikas Corporation (MRVC). The existing flyover currently occupies the alignment needed for laying the additional tracks, and the revised structure is intended to provide space for the new line and improve segregation between suburban and long-distance operations.
Railway officials say the approach will use precast and other advanced construction techniques to complete demolition, rebuilding and commissioning within the mega block, subject to final approvals and detailed planning. The work involves major civil components, including construction of multiple bridges and significant earthwork, along with station and utility-related modifications such as new island platforms and foot over bridges, electrical buildings, signalling and telecommunication works.
During the 45-day block, Harbour Line services between Bandra and Goregaon are expected to be suspended or curtailed, with many trains terminating at Bandra, while traffic management planning is prepared to reduce disruption for daily passengers.
