Over the weekend, Afcons deployed a trench cutter machine near Galta Gate to initiate trenching works for constructing the diaphragm wall (D-wall) for the tunnel boring machine (TBM) launch shaft. This crucial site on NH-248 will consist of a cut-and-cover tunnel, a TBM launch shaft, and a ramp leading to the elevated Transport Nagar Station.
