Atlanta ? Catherine Hartman is familiar with the concrete barrier where a bus carrying a baseball team from a small Ohio college crashed last week. Five years ago, she and her husband were in an accident at the same spot after she mistook the exit ramp for a commuter lane.

Today, with her left knee still not healed, she feels upset that more hasn’t been done.

Investigators said the driver of the Bluffton University team bus also apparently mistook that same exit ramp for a highway lane on March 2 and overshot a stop sign at the top of the ramp. The bus slammed into the concrete barrier, flipped and fell 30 feet onto the pavement below. Six people were killed and 28 people were hospitalized.

On Friday, Atlanta police released to The Associated Press through Georgia’s Open Records Act three reports on accidents at the intersection of Interstate 75 and Northside Drive from 2002 to 2003, all involving drivers who didn’t know they had left the I-75 high occupancy vehicle lane.

Before the Bluffton University accident, the Georgia Department of Transportation said there had been two deaths from seven accidents involving that exit ramp in the past nine years.
