BURR RIDGE, Ill. (AP) — Illinois State Police have honored a trooper killed 17 years ago in a helicopter crash with a sign along Interstate 55 outside Chicago.

Trooper Erin Sweeney Hehl was honored during a special dedication ceremony at the Burr Ridge Police Department last week. The Illinois Department of Transportation posted Trooper Erin Hehl Memorial Over pass signs earlier this year on both sides of the Illinois Route 83 overpass on Interstate 55.

Hehl was 34-years-old when she and 42-year-old pilot George Kurelic were killed in a 1997 crash at Frankfort Airport. Kurelic was a civilian pilot and veteran. There is a memorial for him at the Illinois State Police northern Air Operations Bureau.
