3 dead, multiple people hurt in Greyhound bus crash off Illinois interstate

A Greyhound bus hit three commercial vehicles parked on an Interstate 70 exit ramp overnight Wednesday, killing three of the people on board and seriously injuring at least 14, state police said.

It happened at about 1:55 a.m. on the exit ramp to the Silver Lake westbound rest area in Madison County, state police added.

Four of the injured were flown to hospitals by helicopter and at least ten were taken by ambulance. No one in the commercial vehicles was hurt, police said.

Greyhound told CBS News the bus was heading from Indianapolis to St. Louis and that the driver was among the people hospitalized.

"Our primary concern is ensuring we care for our passengers and driver at this time. We are working closely with local authorities and a relief bus is on the way for passengers," Greyhound spokesperson Lourdes Brown said.
