Nashik: National Highways Authority of India (NHAI) has urged Nashik Municipal Corporation (NMC) to take immediate measures to address persistent slush accumulation on a key stretch of the national highway, following a series of two-wheeler accidents during a recent spell of rain.According to NHAI, excavation work on adjoining municipal roads has left loose soil that washes onto the highway during rainfall, creating a slippery surface and posing a serious risk to commuters. Several motorcyclists have reportedly skidded and fallen over the past two days due to the mud-covered road.The problem is most severe along the busy Mumbai Naka-Dwarka corridor and the stretch near Tractor House beneath the Dwarka flyover. While NHAI teams have been repeatedly washing the highway to remove mud and improve safety, an official said, “A lasting solution lies in preventing soil from reaching the highway in the first place.”The authority has told NMC to address the issue at its source and has also informed local police about the recurring safety hazard.Motorists, however, said the problem was far from new, pointing out that slush accumulation between Tractor House and Mumbai Naka had become an annual monsoon menace, with bikers routinely losing control on the stretch.Residents said the issue had persisted since the construction of the flyover. Although NHAI increased the height of plantation dividers and carried out regular repairs to curb leakages, accidents continue to occur during the rainy season. “The flyover itself contributes to the problem. Mud deposited on the road by heavy vehicles remains trapped beneath the structure and is not easily washed away by rainwater, leaving behind a slick surface that endangers motorists,” a commuter said.With the monsoon in full swing, the motorists have called for more effective and permanent measures to prevent slush build-up and ensure safer travel on the busy highway corridor.
