Unbridled lust for speed has snuffed out more than 40 lives in Jamshedpur since January, prompting the traffic department to identify 11 mishap magnet stretches in the steel city where speed breakers will be raised.

The "black spots", as they are being labelled, will also boast safety signs and reflective road paint or studs to demarcate sharp bends, railings, medians, trees or obstacles, said traffic DSP Vivekanand Thakur, adding that they would approach Jusco for necessary logistics support to install the speed breakers.

The listed 11 accident-prone spots in the city include Sankosai crossing on Dimna Road; Nildih on Golmuri-Telco Road; the turning near Domuhani on Marine Drive in Sonari; Kharkai Link Road near St Mary's English School in Bistupur; Bhuiyandih-Agrico road in Sitaramdera; near Hathi-Ghora temple on Sakchi-Mango road; near Police Lines on Sakchi-Golmuri road, on Jugsalai-Station road in Bagbera; and Parsudih-Station road.

"The speed breakers will compel both small vehicles like bikes and heavy vehicles like trailers, which are almost always guilty of speeding, to slow down. We shall ensure that the road bumps at the identified eleven points come up within a fortnight," Thakur said.

The traffic DSP said apart from raising speed breakers, they would put up distinct road safety signs such as 'Drive Slow' or 'Turning Ahead' to warn bikers and drivers. "We hope to curb bloodspill to a considerable extent this way," he added.

Between January and April 16, 41 persons have died in road accidents in Jamshedpur, at least 17 of them on the spot. The stretch near St Mary's English School on Kharkai Link Road in Bistupur, Bhuiyandih-Agrico road in Sitaramdera, Dimna Road in Mango and Jugsalai-Station road in Bagbera accounted for more than one fatal mishap during this period.

On Saturday evening, a 20-year-old woman, Hardeep Kaur, was killed on the spot when the scooter on which she was riding with her father, Satpal Singh, was hit by a speeding truck near Nildih on Golmuri-Telco road. Singh (52), a resident of Telco, is undergoing treatment in the intensive care unit of Tata Main Hospital.

On Friday evening, student Rohit Verma (20) was fatally injured when his bike was hit by a truck while he was trying to overtake the heavy vehicle at Sankosai. Rohit was rushed to MGM Medical College and Hospital in Sakchi, where he succumbed to his injuries.

A day before Rohit, 40-year-old Sanoj Sharma, a construction supervisor, was run over by a speeding trailer near Kapali bustee on Marine Drive, triggering a roadblock.

Earlier, on April 2, 32-year-old Chandan Karmakar, an employee of Tata Cummins, was killed on the spot and his pillion-rider seriously injured when the bike they were riding at break-neck speed rammed into a divider near Golmuri Police Lines.
