CHENNAI: Chennai Metro Rail is set to bridge the gap on the elevated stretch linking Guindy to Alandur Metro Rail Station by erecting a steel girder rail overbridge near the Guindy suburban railway station.
A Metro Rail source told Express that work is in progress to complete the bridge which is about 105 metres long.
The bridge will be connected by steel girders. The superstructure is fabricated at the yard and assembled on the piers of the approach station area, and will be launched to its final position by nose launching method.
So far, 38 metres of superstructure has been moved towards the location. After it is launched to its final span locations, the bridge will be lowered over the respective bearing and deck slab will be cast to pave way for track works.
The whole process will take around 15 to 25 days. The work will be carried out only between midnight and 3.30 am when there are no trains crossing the area. “It is a challenging task and utmost care has to be taken to complete the work,” said Chennai Metro Rail chief general manager Somasundaram.
