A health check of five flyovers — including Gariahat, Park Street and AJC Bose Road flyovers — is under way, officials of the Hooghly River Bridge Commissioners (HRBC), the custodian of the structures, said.
Railways consultancy firm RITES has been hired by the HRBC to do the health study and submit a report on the repairs that are required and how to go ahead with them.
The Kidderpore flyover and the New Lockgate flyover in Cossipore are also undergoing health check-up that began in December.
The five flyovers were built in the 2000s.
An officer of Calcutta police said HRBC had sent them an application to allow RITES to conduct a radiography test, a non-destructive test and inspection of the expansion joints, among other procedures.
