Atlanta police are trying to figure out what caused a driver to go through a guardrail and off the side of a downtown bridge.
Channel 2's Shae Rozzi was working on another story when she heard a crash along the other end of the Martin Luther King Jr. Drive bridge just before 6:30 p.m. Wednesday.
A person ran up to her live truck to tell Rozzi and her photographer that someone had just driven through the railing and landed 30-50 feet below.
Police said the SUV, which had three people inside was traveling eastbound when it turned left into oncoming traffic and crashed through guardrails between Spring Street and Centennial Olympic Park Drive.
Rozzi watched as paramedics worked on two of the people inside.
Investigators told Rozzi the crash may have been due to a medical emergency, but they are still investigating.
All three people were alert, conscious and breathing when police arrived at the scene, police said.
"It's giving me jitters right now just to see how it could have happened and everybody survived," Jeffrey McBrayer told Channel 2's Amy Napier Viteri after seeing the damage.
All three were taken to Grady Memorial Hospital to be checked out.
Police said the right hand westbound lane on MLK Jr. Drive as well as the sidewalk would remain closed until crews could repair the guardrail.
