Two people in that car were the injured motorists, who later died police said. The driver of that car was also at fault during the crash because it was being driven at “excessive speeds” just before the wreck, according to Raleigh police.

The other car involved, also a sedan, was able to stop with no injuries and little damage to the vehicle, police said.

Saturday afternoon and evening, Wade Avenue traffic was backed up to Edwards Mill Road as emergency personnel had a perimeter around the scene. I-40 traffic was backed up to Chapel Hill Road.
