PUNE (Metro Rail News):  MahaMetro on Friday erected a 79-metre-long girder crossing the railway lines where the Metro viaduct takes a turn towards Range Hills. It is among the biggest girders launched in the Pune Metro project so far. The long web girder was kept ready to save time and the construction to launch this was going on at Khadki for the past six months. The Pune Lonavala railway route had to be closed for 5 hours to get the web girder launched from the railway track.

A temporary structure of 650 tonnes was built to support this 600 tons girder. 30,000 bolts which are made of special metal were used to construct this. The width of this open web girder is 9.7 m, height is 10 m and the length is 79 m and is made from the E 35D steel grade plate. The entire 600-tons open web girder was placed on a specially made roller. Using two large witting machines, the great girder was moved forward by the push-long method. The launch of this girder has resulted in the smooth running of the advanced route from PCMC to Range Hill.

The task of putting out the open web girder was very risky therefore permission was taken from the Commissioner of Railway Safety and the Commissioner of Metro Railway Safety for this purpose.
