The extension of Metro will drive up the project cost from Rs4,219 crore by another Rs320 crore. 1km Metro corridor will cost the exchequer Rs160 crore.
DMRC the consultant for the Trivandrum Metro Rail project has started the study for the feasibility of extending the 21.82-km Technocity-Karamana Metro rail to Pappanamcode and for extending the flyover at Ulloor to Medical College.
The idea of extending the Metro to Pappanamcode was mooted at a high-level meeting chaired by Chief Minister Pinarayi Vijayan held on July 19.
DMRC has already collected details from NATPAC and PWD about the geometrics of the 2Km NH-66 from Karamana To Pappanamcode and also about the Karamana Bridge.
In the coming days, traffic survey will be carried out if the initial feasibility report supports its extension. The Phase-2 of the Metro project has been proposed from Karamana to Neyyattinkara. The current widening of the Karamna-Kaliyikavilai is being carried out with the Metro project in mind.
Metro needs a station every 7Km. The 20th station will come up in Kaimanam and the 21st station at Pappanamcode so Land will have to be found and acquired by the State near Kaimanam and Pappanamcode junctions. At least 30 cents of land is required for each station and the extension of Metro will drive up the project cost from Rs4,219 crore by another Rs320 crore. 1km Metro corridor will cost the exchequer Rs160 crore.
Fortunately, the median is wide enough to accommodate single piers of the sleek box girders of the elevated Metro Rail System.
