Bids open for CMBT-Puzhuthivakkam stretch

The elevated corridor consists of two disjointed sections on either side of the double-decker lines from Power House to Porur. The first section runs for 3.2 km from CMBT to Alwartiru Nagar with three stations at Grain Market, Sai Nagar Bus Stop and Elango Nagar, and the second section for 9 km from Porur Junction to Puzhuthivakkam with nine stations at Mugalivakkam, DLF IT SEZ, Sathya Nagar, CTC, Butt Road, Alandur, Adambakkam, Vanuvampet and Puzhuthivakkam.

As part of this tender, an integrated grate separator from Mugalivakkam to MIOT Hospital and an underpass at Vanuvampet would be constructed by the Metro rail.
