CHENNAI: Chennai Metro Rail Limited (CMRL) has completed the casting of all 513 piers for the 11.3 km Phase 2 Corridor 5 between Ullagaram and Elcot Metro stations. The final pier, P814, was cast near Medavakkam-I Metro station.
The stretch around Medavakkam includes some of the tallest piers in the package, reaching about 29 metres. The alignment crosses the existing Medavakkam Flyover at this height and includes a 57 metre steel girder span along a 125 metre radius curve. Medavakkam-1 and Medavakkam-2 Metro stations are also being built at about 29 metres above road level.
