West Bengal government will demolish the Marjerhat Bridge, a portion of which came down on September 4, killing three people and leaving more than 20 people injured.Chief Minister Mamata Banerjee on Friday said that the inquiry committee headed by Chief Secretary Malay Kumar De has recommended razing down the bridge and constructing a new bridge on the Diamond Harbour Road in a time of one year. After the collapse of the bridge, Ms Banerjee had set up a committee headed by Chief Secretary to look into the reasons for the collapse.“He (the Chief Secretary) has pointed out two things…It was the responsibility of the PWD (Public Works Department) and their negligence is to be blamed… The metro construction work might have had an impact on the structure but it needs to be probed further,” Ms Banerjee told journalists at the State Secretariat.She also clarified that the work of Joka-BBD Bag Metro project was closed on the site of bridge collapse only for seven days for necessary inspection. “Some people have said that I stopped the work of Joka BBD bag. How can I stop the work which I started?” she said. The Chief Minister later told journalists the officials of PWD did not raise the issue of the poor maintenance of a bridge with the Minister of department, thereby giving a clean chit to the Minister Arup Biswas. She also said that talks are on with Railway authorities on constructing a level crossing at the site of the collapse. The 54-year-old Majerhat Bridge is a railway over bridge on the suburban line, which connects Sealdah with Budge Budge. The bridge on Diamond Harbour Road connects Behala and its adjoining suburbs to the city. “The State government has proposed to bear all the cost of the level crossing… We can allow small vehicles and buses to use the railway level crossing. This would give some reprive to the people as Durga Puja is approaching and so is Ganga Sagar Mela,” the Chief Minister said. The Majerhat Bridge collapse was the second such tragedy in Kolkata since March 2016, when a portion of under construction Vivekananda Flyover collapsed in north Kolkata killing 27 people. After the Majerhat Bridge collapse, Ms Banerjee had said that 20 bridges in the city and adjoining suburbs have crossed their expiry date.
