An engineering lapse during the installation of a girder by the Mumbai Metropolitan Region Development Authority (MMRDA) contractors on the Airoli-Katai Naka road overbridge led to the shutting down of trans-harbour local train services for five and a half hours during Friday morning rush hours, leading to the cancellation of 58 services.

Commuters suffered as Navi Mumbai Municipal Transport and Kalyan Dombivli Municipal Transport collectively ran just a handful of train services—43. The suspension of services between 7.10 am and 11.30 am caused significant inconvenience for commuters. Sources said the  58-metre girder, weighing 70 metric tonnes, was tilted, triggering safety concerns and leading to disruptions in train services.
