A man in his 50’s has died in a single-vehicle collision on the 416 north of Kemptville. The car hit an overpass, flipped over and burst into flames. Other motorists stopped and managed to upright the vehicle and to drag the man from the burning car. They administered CPR until paramedics arrived. The man had no vital signs and was pronounced dead a few moments later. The 416 northbound has been reduced to one lane for most of the afternoon and the 416 south is closed with traffic being diverted out the Dilworth exit.
