Kolkata: Following Posta and Siliguri, another under-construction bridge collapsed at Kakdwip in South 24-Parganas on Monday morning. However, no one was injured. A detailed investigation has already been ordered by Sundarban development minister Manturam Pakhira. According to locals, the bridge was sanctioned and work started approximately two years ago. It was being constructed to connect West Steamer Ghat and West Gangadharpur. On Monday at around 10 am, locals heard a loud noise. When they moved towards the source of the sound, they found that a large portion of the bridge had collapsed. Administrative wings of the Sub-Division and the District Magistrate were immediately informed. Police also reached the spot to secure the area. Later, government officials arrived and inspected the situation thoroughly. “Some children were playing nearby. But all of them are safe,” said a local resident. Some of the locals claimed that during the construction of the bridge, a crack was found. But following an inspection by the engineers, a green signal was given to continue with the construction work. According to the government officials, there might have been some fault in the girders. Sources informed that the agency which was given the contract, has been showcaused by the Sundarban development department. The Sundarban development minister also raised finger toward the construction agency. A high power committee has also been formed following the incident. Four contractors have been ordered to appear before government officials on Tuesday by Pakhira.
