MMRDA completes key steel span for Mumbai Metro Line 2B over Central Railway

The Mumbai Metropolitan Region Development Authority MMRDA has successfully completed the installation of a key steel composite span for Mumbai Metro Line 2B across the Central Railway Harbour Line corridor between Kurla and Tilak Nagar stations marking a major milestone in the projectrsquos progressCritical Infrastructure Milestone AchievedAccording to MMRDA the work forms part of Phase III Saraswat Nagar to Chembur a crucial stretch aimed at enhancing connectivity across Mumbai The authority stated that the completion of this span will help link major northndashsouth and eastndashwest transit routes improving overall urban mobilityThe operation was executed within a designated railway block period ensuring that suburban rail services continued without disruptionComplex Engineering Over Active Railway LineThe structure erected between Pier P663 and P664 near Kurla East crosses the busy CSMTndashPanvel Harbour Line MMRDA said the steel span measures 415 metres in length 11 metres in width and weighs approximately 178 metric tonnesThe span comprises two composite steel girders forming a robust structural system These components were fabricated in Hyderabad transported to Mumbai and assembled near the site before being launchedHighPrecision Launching OperationMMRDA highlighted that the launching process required meticulous planning and coordination The operation involved tandem lifting using two 500tonne capacity cranes supported by an additional standby crane to ensure safetyThe girders were lifted and positioned with precision in a constrained railway environment with the entire process completed within the approved time windowCoordination and Safety ComplianceThe authority attributed the success of the operation to close coordination with multiple railway departments including track electrical overhead equipment and safety teams It emphasised strict adherence to all statutory approvals and railway safety protocolsSanjay Mukherjee Metropolitan Commissioner MMRDA stated that executing work over an active railway corridor requires detailed planning and a high degree of precision He noted that completing such complex tasks within limited time blocks is critical to ensuring the timely progress of Metro Line 2BMetro Line 2B Project OverviewMetro Line 2B is being developed in multiple phases includingPhase II DN Nagar to Saraswat Nagar A 753kilometre stretch with six stationsPhase III Bandra to Chembur A 1003kilometre corridor featuring eight stations including key locations such as Bandra Kurla East and ChemburThe corridor will also feature notable engineering structures including cablestayed and balanced cantilever bridgesIntegration with Mumbairsquos Transport NetworkMMRDA said Metro Line 2B will integrate with several major transit systems including existing metro lines suburban rail networks the monorail and future highspeed rail infrastructure The corridor will serve as a southern extension of Metro Line 2A strengthening connectivity across the metropolitan regionExpected Benefits for CommutersThe authority noted that the project is expected to reduce travel time decongest road networks and promote seamless multimodal transport It will also contribute to environmental sustainability by lowering vehicular emissions and improving overall commuter experienceMMRDA added that the successful execution of this complex operation reflects its capability to deliver largescale infrastructure projects in challenging urban environments while maintaining high safety standards
