Four trees and a toilet block are blocking the demolition of the Sion Road Over Bridge, which has been shut since August 2024. The railways have sent a letter to the Brihanmumbai Municipal Corporation (BMC) expressing urgency in addressing these hurdles, as work on the bridge has been severely delayed, the officials said.

The bridge is being rebuilt as part of a larger project to lay the fifth and sixth railway lines between Parel and Kurla.
