The expansion of the fifth and sixth lines on Central Railway (CR), for which the Sion bridge is being demolished, is facing several hurdles, including the acquisition of about 14,626 sq m of land between Kurla and Chhatrapati Shivaji Maharaj Terminus (CSMT). After the Sion connector is reconstructed a few years from now, the Dharavi road overbridge will be razed, officials said. “The Dharavi bridge has been put on the demolition list to make way for a wider and bigger connector, but the work will only be undertaken after completion of the Sion bridge,” an official said.

Six months after Sion bridge was shut in August, mid-day had highlighted how four trees and a toilet block were blocking the demolition of the structure. Railway authorities have written to the Brihanmumbai Municipal Corporation (BMC), asking that hurdles to the demolition be removed speedily. The mail express line corridor comprising the fifth and sixth lines that start from Kalyan and end at Vidyavihar is being extended to Parel in phase one and all the way to CSMT in phase two.
