Kottayam: The old railway bridge in the heart of Kottayam town will be brought down by a controlled demolition at 11am today. The blast will be remotely controlled.
No trains will be operated on the Kottayam route from 9 am to 6.30 pm today (Saturday). No vehicular traffic through Nagampadam bridge will be allowed from 11am to 12 noon. Pedestrians will not be let within 100 metres of the bridge during that time.
The bridge and its pillars were drilled and explosives were placed in inside yesterday. The entire bridge has been covered with a plastic material to stop spread of debris and dust.
The demolition will take place between 11am and 12noon. The bridge is on a stretch of the busy MC Road. Electricity will be cut off in this area during this one-hour window. People can watch the demolition from Nehru Stadium.
After the blast, the bridge will fall on to the tracks. The debris will be cleared by 6.30pm today.
Top railway authorities, district heads, police, firefighters and municipal authorities will be present.
The same technique used to raze down big buildings globally will be employed here. Common in the West, this controlled demolition will be the first of its kind in state. The contract has gone to Tirupur-based Mag Link Infra Projects. They will employ the ‘implosion’ technique used to bring down tall buildings.
Inorder to raze the bridge, concrete beams and pillars were weakened over time first. This was done by the end of February. Beams, pillars and base of bridge were fitted with nitroglycerine and dynamite in a process called charge. These part were drilled and explosives inserted.
