Two of Calcutta’s bridges, one in Baghajatin and another in Kalighat, would undergo thorough repair that would help the structures bear more vehicular load, the urban development department has decided recently.
The concrete used for constructing the decks slabs of the Baghajatin bridge that stands over railway tracks on EM Bypass would be strengthened and its entire underbelly would be covered with a carbon-fibre wrap to reinforce the structure. Following this, steel props would be set up to hold the concrete deck slab of the bridge.
For the Kalighat bridge, special bonding agents would be used to fill up micro-cracks that have developed on the structure. A steel casing would be used around the structure like a jacket and the bridge will get an anti-corrosive paint.
