CINCINNATI (AP) — The Cincinnati police chief is urging morning commuters to plan ahead after an interstate overpass undergoing demolition collapsed, killing one person and injuring another.

Police chief Jeff Blackwell asks drivers to stay away from the collapsed overpass north of downtown Cincinnati and leave with plenty of time to get to work Tuesday.

Authorities say a construction worker was killed and a tractor-trailer driver injured when the Interstate 75 overpass collapsed about 10:30 p.m. Monday.

Blackwell called it a workplace accident, saying crews were taking down an old bridge when something went "terribly wrong."

The truck driver was taken to the University of Cincinnati Medical Center with minor injuries.
