Over time, it would replace and absolve the 1903 treaty. 1 October 1979, the Panama Canal Zone was abolished. All unused area (mainly forest) was transferred to Panama. Also some non-military constructions, like hospitals and schools, were transferred to Panama. Between 1979 and 31 December 1999 U.S. transferred all military areas and constructions to Panama.
