Andhra bridge comes up in five hours!


A concrete block for the road under bridge being put in place by a giant crane on Saturday.
ADILABAD: Building bridges has invariably been time consuming, but this one on a railway line was laid in under five hours, without causing any dislocation of running of trains.
A 16-metre wide road under bridge (RUB) was put into place under the BG line connecting Adilabad with Pimplakuti on Saturday in such a quick time.
The site of the bridge is located close to the Ganesh mandir by the side of NH 7. This structure with a four-metre wide passage was constructed for the convenience of residents of Mahalaxmiwada and Chilkuri Laxminagar for gaining access to Adilabad town.
A five-hour ‘line break' was taken soon after the Nandigram Express crossed the site.
The rails were removed to make way for excavating the ramp to clear a portion roughly five metres in length. It took just over one hour to accomplish this job including dumping cement concrete dry mix to act as basement for the bridge.
The actual structure of the bridge consists of six square blocks each measuring 4x4 metres and weighing about 45 tonnes. These blocks were moved into respective position by two huge cranes that consumed another two hours. The gaps on either side of the blocks were closed and the rails were refitted in the remaining time. About 70 officials, labourers, operators and technicians were deployed for the task.
This is the second RUB after the one at Bhoraj on the same line to be constructed in this fashion. Two more near Gimma in Jainad mandal and one at Kosai in Talamadugu mandal will be laid shortly, according to South Central Railway officials.
