State Route 78 or SR-78 is a state route and partial freeway in the U.S. state of California. The road forms an east-west route between Oceanside and Blythe. The section up to Escondido is designed as a motorway and is called the Ronald Packard Parkway. The highway section is 26 kilometers long, the total route is 310 kilometers long, and runs until just before the border with Arizona.
Travel directions
Oceanside – Escondido
The highway begins at Interstate 5 in Oceanside, a suburb of 173,000 people, north of San Diego. The highway has 2×3 lanes, and runs along an elongated business park in Oceanside. After Oceanside you enter the city of Vista, which is much thinner than Oceanside. Here the houses are scattered throughout the site. It is almost a continuously built-up area until San Marcos. The highway eventually ends in Escondido, at Interstate 15. Escondido has a population of 141,000 and is located halfway between the Los Angeles and San Diego metropolitan areas, but actually belongs to the San Diego metropolitan area. The first suburbs of Los Angeles are only 50 kilometers to the north.
Escondido – Blythea
State Route 78 at Santa Ysabel.
Outside Escondido, State Route 78 becomes single-lane, the only larger town east of Escondido is Ramona. The road also rises between the two places from 100 to 450 meters. The road then heads into the Santa Rosa Mountains and rises to nearly 1,300 meters around the village of Julian. The road then drops abruptly to 800 meters at Banner, where the terrain is more like a desert. The first part is still mountainous, but eventually turns into the hot and flatter Imperial Valley. The road eventually descends below sea level at the Salton Sea.
The road is quite a long stretch in the Imperial Valley with State Route 86 double-numbered to Brawley. This part is a 2×2 divided highway with intersections. Around Brawley, the Imperial Valley is irrigated with much agriculture. East of Brawley, the road heads through the Colorado Desert and curves north. This is sparsely populated and remote area. One then reaches the valley of the Colorado River, which forms the border with Arizona. This area has been irrigated again. State Route 78 then terminates at a junction with Interstate 10 at Blythe.
History
The first section of the highway was opened in April 1962 through the eastern suburbs of Vista and San Marcos, to I-15. The section through Oceanside was constructed in 1966-1967, but there was still a missing link until 1971. In 1973 the interchange with I-5 opened in Oceanside. A number of connections were adapted in the 1990s, but the highway was not widened.
In 1969 there were plans to extend the highway eastwards through Escondido, but due to lack of money this was not carried out then, and later never started again.
