A double-decker bus traveling off its route hit a low railroad bridge overhead and flipped on its side early Saturday, killing four people and critically injuring others, authorities said.
The Megabus was carrying more than two dozen people when it rammed into the bridge around 2:30 a.m. on the Onondaga Lake Parkway in Salina, a suburb of Syracuse in central New York.
Twenty-four people were taken to hospitals, including some suffering from critical injuries.
The bus was too tall to make it under the low-hanging span, said Larry Ives, supervisor of dispatch operations for the Onondaga County Sheriff's Department.
It struck the bridge between two large signs warning that the clearance was 10 feet, 9 inches, photographs from WSYR-TV showed. The top level of the bus was crushed and partially peeled back in the front.
The driver of the bus had head injuries but was speaking to investigators, Onondaga County sheriff's deputy Herb Wiggins told The Post-Standard newspaper of Syracuse.
The dead included three men and a woman, Sheriff Kevin Walsh told the newspaper. He said there was no indication the driver had been drinking or using drugs.
The bus left Philadelphia at 10 p.m. Friday and was headed for Toronto with stops in Syracuse and Buffalo, said Don Carmichael, a senior vice president at Coach USA, which operates Megabus. He said he didn't know why the bus was off its route but was headed to the crash site early Saturday to investigate.
The crash shut down the parkway, which runs along a lake not far from the intersection of the two major highways that go through Syracuse, Interstate 81 and Interstate 90.
