Mumbai’s Metro-3 to get new technology for tunnelling work

To overcome the restrictions caused by the city’s narrow roads and congested spaces, the Mumbai Metro Rail Corporation (MMRC) will adopt new technology for its tunnelling work for Metro-3 starting this January. The MMRC will use the New Austrian Tunnelling Method (NATM) to widen the tunnels underground, so as to create additional space for stations.
