Bids Invited for Chennai Metro Line-5’s Underground Work

Like Line-3’s 26.72 km underground section (Madhavaram – Taramani Link Road), this package will also be funded through an ODA loan by Japan International Cooperation Agency (JICA).

CMRL requires a minimum of 4 TBMs to be used for tunneling here and out of those 2 must be sourced from Japanese manufacturers, per the conditions laid out by JICA.

      A heavy ‘metro’ rail system is not being pursued anymore. Project will now be built as a light rail ‘metrolite’ system. Revised DPR is ready and currently pending AP govt’s approval.
