All lanes were open at 6 p.m. after a one-vehicle rollover accident about 3 p.m. Friday, according to authorities.
The accident initially caused a traffic backup to the Arlington-Grand Prairie border and closed the exit ramp from Interstate-30 leading to Six Flags Drive and Texas 360.
One person was ejected from a Ford Explorer which overturned during the accident. That person was taken to an area hospital by helicopter ambulance, police said. Two other people in the Explorer were taken to area hospitals by ground ambulance, police said.
The accident was still under investigation late Friday.
