Police say that driver, a 23-year-old woman, lost control of the Mazda, hit a median, veered across the three-lane highway, and hit a Peco building.
An Action News viewer caught the crash on camera. The video shows the car bouncing off the building and coming to a rest on the sidewalk.
"I would say she was going 70-80 mph," said Tim McKibbin.
