 In 1969 , plans to extend the freeway portion of SR 78 east from the Broadway interchange through Escondido were delayed by Caltrans director Jacob Dekema due to a lack of funding until 1980 . However , in 1970 , the community raised concerns about the number of buildings that would need to be destroyed , as the freeway would go through a dense urban area . Other routes , including routing SR 78 along I @-@ 15 south , were proposed . The majority of the Escondido City Council supported sending representatives to the upcoming California Coastal Commission meeting in January 1971 to expedite the process of construction .
