A big rig (unknown if loaded) rolled over and came to rest on its side in the middle of a busy tri-intersection in Commerce. Atlantic, Telegraph, and Eastern all come together near the 5 freeway. Parts of the intersection are open but will be shutdown to upright the big rig and trailer. If the trailer is loaded the upright time will be extended. The female driver was not injured and was helped out of the rig by a Good Sam.
