The Brihanmumbai Municipal Corporation (BMC) has officially set deadlines for the completion of two major infrastructure projects in Mumbai - the Sion and Belasis flyovers. These flyovers are considered critical to easing congestion and improving east-west connectivity across central parts of the city.
With both bridges spanning railway lines and connecting key neighbourhoods, the projects are expected to significantly enhance traffic movement and reduce bottlenecks once completed. The BMC aims to ensure timely execution through coordinated efforts with various civic and railway departments.
Sion flyover completion date
BMC Additional Municipal Commissioner (Projects) Abhijit Bangar inspected the ongoing construction work at the Sion flyover site and emphasised the need for timely execution. As per the BMC, the flyover is scheduled to be completed by May 31, 2026.
Key highlights of the Sion flyover project:
- The bridge connects the eastern and western parts of Mumbai.
- The southern side foot overbridge (FOB), being constructed by the Railways, is expected to be completed by 31 August 2025.
- Major bridge works will begin after that, with girder installation in the north planned for November 2025 and in the south by January 2026.
- The western approach road via Lal Bahadur Shastri Marg is nearly complete.
- The second underpass will commence on October 1, 2025.
