Two large signs warn drivers of large vehicles not to enter beneath the concrete overpass. One attached to the top of the concrete barrier reads: "High Vehicle STOP Turn Left." The other, placed to the left of the driveway several feet in front of the barrier, says all vehicles higher than the threshold must turn left.
Three people were at hospitals in critical condition. The 27 other surviving passengers were hurt, but their injuries were less extensive, authorities said.
One person died at the scene; the second died later at a hospital. Police said it was not immediately known if charges would be filed.
Osvaldo Lopez, an officer with the Miami-Dade Aviation Department, said he first heard a loud noise Saturday morning and was certain it was some sort of car wreck.
He said he went inside the bus to help and found several passengers thrown into the center aisle. He said the passengers, many of whom were elderly, remained calm after the wreck.
"It was just very bloody," he said of the scene.
After helping the passengers, Lopez suffered injuries of his own - his left arm and a finger on his right hand were both bandaged.
Fire trucks and police cars swarmed the area Saturday morning, and the bus was blocked off by yellow police tape. A cooler that had been filled with water bottles was on its side behind the bus, the front of which remained wedged beneath the overpass for hours before it was towed away.
The bus was privately owned and typically used for tours, though police believe all the passengers were local residents, said Miami-Dade Police Lt. Rosanna Cordero-Stutz. The driver was unfamiliar with the area near the airport and did not intend to wind up at the arrivals area, Cordero-Stutz said. The driver was being interviewed by investigators, she said.
The bus was going about 20 m.p.h. when it hit the overpass, Chin said.
The bus model is commonly used for charters and tours, with the driver seated low to the ground and passenger seats in an elevated area behind the driver's seat.
