The government has floated a tender to dismantle the vulnerable portions of the Vivekananda Road flyover, a portion of which had collapsed in March 2016.
The government is yet to decide whether the rest of the structure will be pulled down or allowed to stand to facilitate reconstruction of the flyover.
Officials said another tender would be floated to assess the health of the rest of the structure.
An engineer of the Calcutta Metropolitan Development Authority, the custodian of the flyover, said the steel structures that did not have any concrete above them would be taken down. The piers and the pier caps will be untouched.
