As part of the construction of twin tunnels for the Goregaon-Mulund Link Road (GMLR), the Brihanmumbai Municipal Corporation (BMC) on Thursday said that excavation using tunnel boring machines (TBMs) will begin in June.

At present, the work of the ‘launching shaft’ for the twin tunnels has been completed, and concrete pouring in the cradle is underway. Two tunnel boring machines will be used for the construction of the underground twin tunnels. After completion of the first phase of excavation work, the process of lowering the tunnel boring machine into the shaft will begin on March 10.
