After securing the Railways’ cooperation, the consortium constructing the Versova-Andheri-Ghatkopar Metro line is in a quandary about the method of constructing a bridge over the railway tracks in Andheri.
As of now, the Mumbai Metro One Pvt Ltd (MMOPL) is constructing the steel bridge by using pre-cast concrete segments in which a number of small segments are cast between two pillars. The Western Railway has agreed to provide blocks of about two to four hours per day for the construction work.
The MMOPL, comprising Reliance Infrastructure, MMRDA and Veolia Transport, is considering another approach which involves constructing the 183-metre-long bridge by launching girders instead of segments. If this approach is taken, the bridge will require just a couple of girders as against many small segments.
However, the alternative girder-launching method will require clearance from the Airport Authority of India (AAI).
