Chennai Metro Rail has kickstarted the work to build a tunnel for the phase II project in the stretch between Greenways Road and Mandaveli.
Greenways Road is one of the important locations in the 116-km long phase II project, and it is a part of corridor 3, which starts at Madhavaram and terminates at SIPCOT, covering various areas including Perambur, Purasawalkam, Sterling Road, Adyar, and Sholinganallur. Four tunnel boring machines (TBM) will be at work here — two to construct a tunnel from Greenways Road to Adyar junction and two from Greenways Road to Mandaveli.
According to officials of Chennai Metro Rail Limited (CMRL), in February, one of the TBMs named ‘Kaveri’ began the tunnelling process towards Adyar. Now, the TBM named ‘Noyyal’ was launched recently at Greenways Road to build a tunnel towards Mandaveli. One more TBM ‘Vaigai’ will start work after a few weeks.
