Bhopal, June 29 -- At least three people were killed in 30 hours as a massive traffic snarl on the Indore-Dewas highway stretched on for nearly eight kilometres between Thursday and Friday, with the Indore administration springing into action on Saturday. The traffic jam, which began on Thursday evening, continued till late on Friday night with over 4000 vehicles stuck on the stretch, causing chaos and raising serious questions about road and traffic management. According to preliminary information, the primary cause of the bottleneck was ongoing highway construction work and severe water-logging due to heavy rainfall. Traffic was diverted to a narrow service lane, which led to extreme congestion and stranded vehicles. The first death was reported on a Thursday evening when Sandeep Patel of Gari Pipalya village, died of a heart attack on the way to the hospital. "Sandeep complained of chest pain. We were taking him to the hospital in Mangalia. The car stranded in the traffic and his condition deteriorated. He was declared brought dead," Sandeep's uncle, Satish Patel, said. htc...
