Even as the progress of the metro rail project of the elevated corridor is at an advanced stage between Koyambedu and St. Thomas Mount, the Chennai Metro Rail Limited has begun soil investigation work at various places near the Madras High Court of the Washermenpet-Chennai Airport route.

K. Rajaraman, Managing Director, CMRL, said that the first stage of soil investigation for the metro work had begun in different places near the Madras High Court for collecting soil data for construction of metro stations and underground tracks. As part of the soil investigation work bore-holing was being executed to collect soil data.

Each bore-holing needs two to three days and as a whole 30 to 45 days for getting soil data for a particular stretch, he added.

At present soil investigation work is in progress at different points on the heavily congested Esplanade Road and NSC Bose Road near the High Court of Madras. Mr. Rajaraman said: “Once the collection of soil data is over the second stage would be the shifting of underground utilities after which tender would be awarded for track and station works.”

The first phase of the project involves two corridors – from Washermenpet to Chennai Airport; and between Chennai Central Station and St. Thomas Mount railway station. The metro rail is scheduled for completion in 2015.

While the elevated corridor work was in progress in three stretches – Koyambedu to Ashok Nagar (4.5 km); Ashok Nagar to St. Thomas Mount (4.4 km); and Saidapet to Officers' Training Academy (5.2 km), underground tunnelling work was yet to start.

The construction work of metro stations on the elevated corridor in Vadapalani and Koyambedu had also begun and contracts have been awarded for construction of eight more elevated stations.

A detailed project reports would be prepared for three new metro routes running a distance of 63 km.

To Thiruvanmiyur

The routes would be from Moolakadai to Thirumangalam (22 km); Moolakadai-Thiruvanmiyur (19 km); and from Luz to Iyyappanthangal (22 km).

Once completed the Metro Rail would run for a total length of 45 km on the two corridors and an estimated six lakh commuters are expected to use the train services daily.
