Authorities have reopened a north side interstate ramp blocked by a predawn truck wreck, but a south side interstate shut down by a fatal wreck remains closed, according to the Georgia Department of Transportation.

On the south side, College Park police are working a wreck that has all lanes of I-85 southbound blocked at I-285. According to GDOT, the wreck, which involves a tractor-trailer and a sport utility vehicle, also involves a fatality.

Southbound traffic is being diverted off I-85 onto Old National Highway, according to the AM750 and 95.5FM News/Talk WSB Traffic Center.

On the north side, the ramp from Peachtree Industrial Boulevard to I-285 westbound reopened about 9 a.m. after being blocked by a truck that overturned and dumped a load of logs onto the roadway before dawn.
