CMRL (Chennai Metro Rail Limited) while ‘decorating’ the interiors of its stations on the elevated corridor with life-size replica of Ajanta and Ellora cave paintings (superimposed on tiles) has also floated tenders to generate revenue through advertisements. Two separate tenders have been floated to advertise on the few hundred piers and portals on Koyambedu-St Thomas Mount corridor. CMRL officials hope that the advertisements will keep posters defacing the city at bay once its massive ad campaign gets going.The advertisements will also replace the dull monotony of the row of concrete pillars with colourful lighting, sometimes decorative lights.
CMRL has fixed the size of advertisements boards at 5ft width and 8ft height maximum for both piers and portals. One of the crucial contractual conditions is that the firm should avoid nailing or drilling on its structures. CMRL has also said a categorical no to loose hanging wires, an otherwise common sight in the city, even at the tender stage.
