A crash closed southbound Interstate 71 in Warren County at the height of the morning commute Wednesday.
All lanes were open shortly after 9 a.m.
The highway was completely shut down when two vehicles collided about 8 a.m. between Kings Mills and Fields Ertel roads.
Injuries were reported.
One lane opened about 30 minutes later, but by then the damage was done.
Traffic backed up into northern Warren County, and vehicles also clogged side streets such as Kings Island Drive.
