The Kolkata Metropolitan Development Authority (KMDA) has started repair work of Kalighat Setu. The authorities have also asked its consultants to suggest as to which flyovers and bridges need the sensors fixed to constantly monitor deviations in their traffic load bearing capacity.

KMDA officials said that the repair work of the 60-year-old Kalighat Setu will include repairing the cracks, retrofitting and overall strengthening. The pillars of the bridge which are on the Tolly’s Nullah have been badly corroded due to the acidic water and need proper treatment to ward off the layers of corrosion.
“Grouting work is to start as the damaged portions of the bridge will be repaired through retrofitting. Work will be conducted slowly with all precautionary measures as the bridge is not in good condition,” an official said.

Officials said as of now Kalighat Setu will undergo short term repairs. The bridge’s upper structure will get a thorough overhaul and eventually in the long run the bridge may be reconstructed. KMDA officials said that they had plans to install smart sensors in some of the flyovers and bridges in the city to keep track of 24 hours real-time data on their static and dynamic vehicular load taking pressure.
