The Colaba-Bandra-Seepz Metro 3 will now not only be underground but also on-ground and elevated. The government agencies – Mumbai Metropolitan Region Development Authority and Mumbai Metro Rail Corporation – are chalking out plans to merge Metro 3 with Swami Samarth Nagar-Jogeshwari-Vikhroli-Kanjurmarg Metro 6.
Senior officials in the government said that they are looking at integrating the two metro lines for which Metro 3 will take the elevated route after Seepz over Jogeshwari-Vikhroli Link Road. It will also briefly go on-ground before taking the elevated route of up to 1.5 km. This would mean that these two metro lines will connect south Mumbai, central Mumbai, western and eastern suburbs.
“From here, it will connect the proposed Metro 6. There is no need for constructing another line,” said a senior official.
Usually it takes around Rs.150 crore per kilometre for creating a metro line, including its signalling, overhead power cables and tracks. This will require change in detailed project report as other changes like number of coaches in Metro 6 is also being thought of. The DPR will help in adapting to the system and specifications of underground metro line with an elevated one to avoid future troubles, the official said.
On Monday the MMRDA which is looking after the execution work Metro line 6 held a meeting and asked officials to prepare a new detailed project report so that both lines do not have glitches of signalling, system and track.
The length of the platform will be increased for line six. Apart from that the signalling system and integration of both lines will cost about Rs.425 crore, according to the official.
