Witnesses described hearing a loud boom Thursday and moments later, finding victims, including construction workers, strewn through the wreckage. Other people were trapped in cars, they said.Giovanni Hernandez said it "sounded like a bomb, like multiple bombs in one.""It sounded like the world was ending, and when you look back, all you see is the bridge on the floor. It was awful," he told CNN affiliate WSVN. Sweetwater police Sgt. Jenna Mendez was stopped at a red light one intersection away when she saw the bridge crumple. At first, she thought, "Why would they have brought the bridge down during the day?"Mendez drove forward, saw crushed vehicles and realized "this was not on purpose, this was a catastrophe," she told CNN.She rushed into the debris and saw injured construction workers atop the detritus, she said.Two men had broken bones, and two others were unconscious -- one who wasn't breathing and the other with a major cut to this head. Mendez started chest compressions on the one who wasn't breathing, she said."I started yelling to civilians in the crowd, 'Please get me doctors. ... I need help up here.' A doctor jumped up, and she started helping," Mendez said.Rescue workers arrived with backboards, and the two unconscious people were taken to a hospital, Mendez said.Officers and others rushed to an SUV that was partially crushed. The driver was killed, but the passenger was rescued, Mendez said."They were able to take a piece of wood, and civilians (and) officers pried that door open and pulled him out of the back seat of that car," she said.Doctors and medical students ran to the scene from a nearby building and started treating victims, said Isabella Carrasco, a student at the University of Miami who had passed under the bridge in a car just before the collapse.Carrasco saw at least five cars crushed beneath the bridge, she said."Someone on the side of the road had asked a police officer if she had heard any response from the people inside the car," Carrasco said, "and she shook her head and said no."Kendall Regional Medical Center received 10 patients, including two in critical condition, said Dr. Mark G. McKenney, the trauma medical director. 2195

With the majority of its 26,000 students displaced and many schools deemed not safe because of the damage, officials are discussing alternative ways to get students back to the classroom or provide psychological aid for them."I would say every single school in Bay County has some type of damage, some more extensive than others," said Steve Moss, vice chairman of Bay District School Board. "Some it'll probably take weeks or months to get online. Some it will take years." 474
