THANE, Jan. 10 -- Four people were injured after a cement-laden truck rammed into multiple vehicles that were being driven on the wrong side of the busiest stretch of Ghodbunder Road near the Gaimukh traffic outpost on Friday morning, triggering a chain collision involving over a dozen vehicles and bringing traffic to a halt. Police said the accident occurred around 6.30am when the truck was descending the Gaimukh ghat and collided with 11 to 12 cars and one or two autorickshaws that had entered the wrong lane to bypass congestion. The truck driver fled the spot and is yet to be traced. Panic followed the crash, prompting cops to rush to the scene. Those injured were identified as auto driver Shivkumar Bechu Prasad Yadav, 56, Ola cab driver Rambali Babulal, 22, and auto passengers Anita Dinesh Petwal, 45, and Taskir Shafiq Ahmed Sheikh, 45. All were admitted to a private hospital in Waghbil. The collision caused massive traffic congestion, with long queues stretching up to the Vasai Creek Bridge. Pankaj Shirsat, DCP (Traffic), Thane, said vehicles were travelling in the wrong lane towards Mira Road when the truck came downhill towards Thane. He said the driver managed to control the vehicle, preventing fatalities, and five cranes were deployed to clear the road by 11.30am. An oil spill at the site further raised safety concerns and was cleared by the disaster management team and fire brigade. Police said that wrong-side driving is making the stretch accident-prone. Residents objected the merger of service lanes with the main Ghodbunder Road, which has forced locals to take 1.5 to 2 km-long detours to reach nearby locations due to the absence of diversions. This has forced motorists to drive in the wrong lanes, causing accidents. Nilesh Patil, a resident of One Hiranandani Park, said, "The merger of service road is illegal. Several housing societies depend on the service roads for daily local travel. After the merger, heavy vehicles and local traffic are forced into the same lane, endangering residents who need to share road space."...
