Traffic on I-675 south is down to one lane from the exit to state Route 235 to the North Fairfield Road exit because of a wreck that occurred just after 6 p.m.
No one is injured in the wreck involving a semi and a car, but the accident scene has shut down one lane and construction is occurring in the other lanes, Fairborn police say.
Exit 20 (Dayton Yellow Springs Road) and exit 17 (North Fairfield Road) are both open, but traffic is slow.
As of 8 p.m., officers remained on scene as the semi's cargo was transferred to another tractor-trailer.
We will update this story as details become available.
