The nearly century-old Zeerut bridge over Tolly’s Nullah, which connects Alipore with the Maidan, requires urgent repairs and, if necessary, replacement, Kolkata Police have written to the state government. The bridge has been bearing heavy traffic loads for decades, the police said in a recent letter to the irrigation department, which is responsible for the structure. ADVERTISEMENTA 2019 report stated that the bridge built in 1929 had outlived its lifespan, but nothing has moved since then. Seven years on, the police have again flagged the concerns about the steel structure. “The top bitumen layer was scraped off a few years back from the bridge to reduce the load,” an irrigation official said.
