"After WWII, the barrio began to change physically. In the 1950s, the zoning laws had been changed by the city of San Diego, from residential to industrial, allowing the influx of Anglo-owned auto junkyards. In 1963, Interstate 5 bisected the Barrio. In '1969 the Coronado Bay Bridge opened with its on-ramps and support pylons piercing the heart of the barrio. Because of the dislocation of families and business closures during these two major construction programs, by 1979 the population of the barrio had declined to approximately five thousand residents. City, state, and federal governments had dictated the policies of change in Barrio Logan. Residents had not realized they could petition City Council and express their opinions; there had been no local discussions regarding community and neighborhood planning. Many of the residents accepted the negative changes in their community as the way things had to be. In 1967, feelings of resignation and hopelessness began to change to those of empowerment, as community leaders began to demand a neighborhood park under the bridge pylons."
