Chennai Metro Rail Limited (CMRL) has recently started the construction work on the underground stations along the Madhavaram-Taramani metro line being executed under the Phase II part of the project. The expansion of Metro Phase-II has been planned with a network length of 118.9 km with 128 stations. It consists of three corridors, namely Corridor-3 from Madhavaram to SIPCOT (45.8 km), Corridor-4 from Lighthouse to Poonamalle Bypass (26.1 km), Corridor-5 from Madhavaram at Sholinganallur (47 km) involving a whopping investment worth Rs 63,246 crore.
The construction of Corridor-3 entails both underground and elevated tracks, running from Madhavaram to Taramani and then SIPCOT, respectively. While tunnelling began a few months back in Madhavaram, the building of underground stations along this stretch has been started after a one-year delay. CMRL selected three contractors to construct the underground stations on the Madhavaram-Taramani line, which was divided into five packages for tenders, including Madhavaram-Perambur, Ayanavaram-Kellys, and KMC-Royapettah. Dinesh Chandra Agarwal Infracon Pvt Ltd and Soma Enterprises won the Madhavaram-Perambur line's contract with the lowest bid in a joint venture.
Tata Projects gets the contract for the Ayanavaram-Kellys stretch with the lowest bid. Rail Vikas Nigam Ltd. secured the remaining contracts for KMC-Royapettah, Dr Radhakrishnan Salai-Adyar Junction, and Adyar Depot-Taramani. The contracts are being awarded to players with a three years completion period to execute the projects of underground stations.
