Countless people were stranded on I-55 Monday following an estimated 100-car pileup.The initial crash happened around 9 a.m., triggering a domino effect that led to multiple subsequent crashes.At least two people were confirmed dead, and dozens more were hurt.Eyewitnesses spoke with WDSU about what they experienced. Many described seeing flames and smelling gasoline before hearing multiple explosions. Several cars were burned as a result.”We were looking for fire extinguishers, and we just all kind of pulled together,” Mary McLin, who was involved in the pileup, said. “We were checking on each other, seeing if everybody was OK.”Another woman went live on Facebook, sharing images of the aftermath with countless others.”We’re seeing fatalities. We’re seeing a lot of people that are hurt. We see some people that are just shaken up,” Clarencia Readus said. Authorities say dense fog and smoke from nearby wildfires contributed to the low visibility.
