Chennai Metro Rail Limited (CMRL) and the Tamil Nadu Road Development Company (TNRDC) are planning to work together on a cutting edge infrastructure project.
The plan is to build a four-lane elevated road on top of the six-lane IT expressway and to build an elevated corridor of Metro Rail above that – sprawling 17 kms – from Taramani to Siruseri.
The elevated road will be the first of the two projects to be built and is expected to be completed in 2 years. The first phase of this will run from SRP Tools junction to Siruseri and will be at a height of 5.5 metres from the road and Metro Rail will be 4.5 metre above that. “As far as possible, we are looking at pre-fab structures so as to reduce time of construction and also since we cannot take much road space during the work,” The Hindu reported an official as saying.
The Chennai Metro stretch above the elevated road will cover 22 stations including Tidel Park, Perungudi, Okkiyampet, Infosys, Sathyabhama University, Siruseri and SIPCOT.
