In a first for city, the Central Railway and MMRDA have manufactured and assembled a foot overbridge, which is now ready to be placed above railway lines between Sion and Kurla stations. Generally, the FOBs are constructed by fitting multiple blocks on the site.

"Assembling the entire structure and placing it above the rail lines would cause least disturbance to the traffic. The foundation structure will be separately erected and the ready FOB will be placed on it. The usual practice is to put up just the girders after taking several blocks and then erecting the bridge structure above the tracks," a senior official said.
