In 1981 a second east–west runway, 26L/8R, was built, necessitating the removal of the old NE-SW runway 4/22. Remnants of the 4/22 runway are visible in the present-day taxiways. With the completion of the new runway, the existing runway 25/7 became 26R/8L. In 1985, the city of Los Angeles acquired Ontario International Airport outright from the city of Ontario. In 1987, Runway 26R/8L was extended to the east to bring the two runway thresholds side by side, so aircraft would be higher over neighborhoods. 26R/8L became the main departing runway and 26L/8R the main arrival runway.
