Eastbound U.S. 78 in DeKalb County has reopened following a wreck Wednesday morning that blocked all lanes for about an hour.

The crash, which involved a tractor-trailer and a smaller vehicle, happened before 10 a.m. at the junction of U.S. 78, also known as the Stone Mountain Freeway, and I-285.

There were only minor injuries in the wreck, according to a DeKalb police spokesman.

The Georgia Department of Transportation initially reported that the wreck happened on I-285 and blocked all northbound lanes of the Perimeter, but those lanes remained open.
