The new interchange with SR 94 was completed in July 1976. In August, the California Highway Commission (CHC) announced that SR 75 south of SR 54 had been removed from the state highway plan. The next year, the county supervisor, a San Diego City councilman, and the mayors of La Mesa and National City wrote a letter to then-Governor Jerry Brown to ask that this portion of SR 125 and other freeways be constructed. There were concerns about the types of congestion seen in Los Angeles coming to San Diego due to the incomplete freeway system. San Diego City Councilman Tom Gade wrote a telegram to the Caltrans Director Adriana Gianturco about the possible deletions; in response, Gianturco clarified that the plans were only being reconsidered and had not been removed, and a CHC member criticized the tone of the original telegram, calling it "intemperate." However, the city of Chula Vista was opposed to the construction at the time, which was a factor in the removal of SR 125 from the highway plans.
