The Chennai Metro Rail Limited (CMRL) on Saturday officially released maps of its ambitious 118.9km phase-2 project that will connect far-flung suburban areas with core localities of the city through three corridors.
As CMRL has released two maps- one is 52km corridor - (Madhavaram to CMBT and from Madhavaram to Sholinganallur linking the eastern part of the city including the IT hub at OMR), other of the entire phase with three corridors. Construction work for the 52km corridor will begin before the end of this year. It comprises 128 stations.
Three corridors of the phase include Madhavaram to Sipcot, Lighthouse to Poonamallee and Madhavaram to Sholinganallur. The estimated cost of the project is Rs 69,000 crore.
While many changes were made to the alignment and to the names of the stations, one of the corridors initially planned to link localities from Lighthouse to CMBT was later extended up to Poonamallee to link high passenger traffic areas like Porur and Iyyapanthangal.
Currently, the soil test is underway for the 52km corridor and a 10km corridor - from Lighthouse to Vadapalani. As Compared to the 45km phase-1, phase-2 will have smaller stations to cut down cost and land required for construction.
