CHICAGO (Reuters) - A collision involving a tour bus and another vehicle on a busy expressway near downtown Chicago sent 20 people to the hospital and temporarily halted all northbound traffic on the highway on Sunday, an emergency official said.
A spokesman for the Chicago Fire Department said the accident occurred around dinner time on the northbound Dan Ryan Expressway (I-90/94), just south of the downtown business district known locally as "The Loop."
Twenty people with injuries, "none serious," were taken to a half a dozen local hospitals, the spokesman said. Another 31 people refused treatment.
The spokesman said the damage to both vehicles was minor and that traffic on the expressway resumed shortly after 7 p.m.
There have been several bus crashes on U.S. highways in recent weeks, including one in Connecticut in March that left 14 people dead and one in Virginia last month that killed four.
