BENGALURU: A mechanical failure occurred nearly 50 feet above the ground at BTM Layout during Metro construction work on Sunday morning, October 24, 2021, when the support leg of a 260-tonne launching girder deployed for constructing the double-decker flyover of the RV Road-Bommasandra line slipped and got distorted. There were no reports of casualties or injuries as the operations of the girder were carried out by remote control.
