According to investigators, two good samaritans pulled over to help after one of the initial collisions, when another crash came careening towards them.
The two men then jumped over a concrete barrier on the freeway to avoid being hit, not knowing there was a 60- foot drop into Crabtree Creek.
A 33-year-old man died as a result of the fall. An 18-year-old survived and was taken to WakeMed for minor injuries.
All lanes of the Outer Beltline were closed between Six Forks Road and Glenwood Avenue.
This is the eighth fatality on Triangle roadways since Wednesday. Police are continuing to investigate.
An equally bizarre, yet strikingly similar incident happened on the same stretch of the Beltline back in 2005.
In that accident, Todd Fletcher, then 26, was driving back to a friend's house when he spotted an accident, and stopped to help.
At some point, presumably to get out of the way of traffic, he stepped over the concrete barrier on the side of the freeway, not realizing in the dark of night that there was a drop to Crabtree Creek.
Fletcher plunged to his death. His body was found a day later.
