PITTSBURGH —

Erin Perry says her parents were on their way to take care of her 93-year-old grandmother when the Forbes Avenue bridge over Fern Hollow Creek in Pittsburgh’s Frick Park collapsed Friday morning.

Tyrone and Velva Perry, both 69, were released from Presbyterian Hospital Saturday night. Erin told sister station WTAE both fractured their vertebrae in the collapse.

"My father actually said every time he closes his eyes, he sees the bridge buckling, so he has experienced trauma. They both experienced trauma," Erin Perry said.

Erin says her father was driving the red pickup truck seen at the bottom of the ravine.

"As they were driving down the bridge, my father described seeing the bridge in front of him buckle, and then he noticed through the rearview mirror that behind them the bridge was buckling, and then they fell…the bridge was collapsing. He knew the bridge was collapsing. He thought he was going to die," Erin Perry said.

"My mother had been on her phone, and so she thought they had got hit by a car, and then was confused as to why they were still moving until it hit the ground… The other thing that happened is that there were cars coming from the other direction, one that flipped over towards them, and then the second came tumbling towards them and landed right beside the vehicle on its side," Erin Perry said.

Erin says her parents were told to get out of the car immediately because there was a gas leak and they had to evacuate the area.

"The sound of the gas, the way it was described, sounded like Niagara Falls," Erin Perry said.

Erin says first responders and accident victims helped her parents get to safety and eventually they were taken in an ambulance to the hospital.

"There was a shell of protection around them, and so they feel just blessed and fortunate to still be here, and then there's this tremendous outpouring of support and prayers and love that is coming from all over the country," Erin Perry said.

Pittsburgh paramedic Jon Atkinson was on his way to the scene of the bridge collapse Friday morning when he heard other first responders were having trouble getting victims out of the ravine.So he offered to use his own four-wheel-drive pickup truck, which he just bought several months ago.Watch the full story in the video player above. "I almost felt like an Uber driver coming down to pick somebody up," said Atkinson, a 21-year veteran.It's doubtful that any Uber drivers have ventured down the steep terrain of Pittsburgh's Frick Park under a collapsed bridge. But Atkinson did it with his truck.He pulled out a woman who was loaded onto the bed of his pickup truck when other rescue vehicles could not get out."They were down there, they had everybody taken care of, and the question was, 'How are we going to get these people out of here?'" Atkinson said.Even though the victim's vital signs were stable, Atkinson said she needed to get out quickly."Even someone who's not critically injured, exposure to the elements is definitely a big problem," he said.He pulled out another victim who did not need to be treated but was concerned about being late to work."He was, surprisingly, uninjured and he just needed to get out of there and wanted to go to work so he hopped in the front with me and we took a cautious route out," Atkinson said.Atkinson is trained as a tactical paramedic but he said his training did not prepare him for this."We don't really train in off-road driving but it's just understood that sometimes you have to do some unorthodox things or think outside the box to meet the needs of the incident and that's what we did today," he said.
