Work resumed in 1999, and was expected to be finished by 2000, at a cost of $ 10 million; the benefits of decreased congestion came into effect once the new westbound offramp was opened. The Twin Oaks Valley Road interchange was another subject of contention, as the state
Assembly refused to fund the project with $ 5.1 million (about $ 8.99 million in 2023 dollars) in April 1997. However, in June 1998, the California Transportation Commission approved the funding after the San Diego Association of Governments officially requested it. Construction began in August 1999, and was scheduled to end in 2001.

The part of the freeway connecting Rancho Santa Fe Road to the Vista portion opened in February 1963, at a cost of $ 3.9 million (about $ 29.7 million in 2023 dollars). The opening of the freeway was credited with helping to bring 315 jobs to San Marcos in 1963. The rest of the freeway between Nordahl Road and US 395 opened on December 21, 1964, providing a four-lane highway from Escondido to Oceanside; the segment cost $ 1,865,000 (about $ 14.2 million in 2023 dollars). SR 78 was officially designated in the

system as SR 195 and
Legislative Route 146. The state legislature added the portion of SR 78 from SR 115 to the Riverside County line in the 1964 state highway renumbering, also naming the road the Ben Hulse Highway. In March 1964, the Ben Hulse Highway leading to Palo Verde was dedicated, and state senator Hulse's efforts to have the road built were recognized. Following this, in 1965, the newly constructed section was signed as CR S78. The section from Palo Verde to Blythe shows up as part of SR 78 on maps as early as 1965, and the section from southwest of Midway Well to Palo Verde is shown as part of SR 78 as early as 1966.

February 2008 to June 2011. On the third phase of the project, from the junction with SR 86 west of Brawley to the western end of the completed bypass, construction began in late 2010. This project was identified in August 2010 as a project that could be affected by California state budget cuts. The Brawley Bypass, as it was known, opened on October 30, 2012.

May 1968 saw the state designating the Jefferson Street and Emerald Drive interchanges as a priority. In August 1968, the state allocated $ 750,000 (about $ 5.02 million in 2023 dollars) for building the Jefferson Street interchange. Further funding difficulties were encountered due to US 395 being given priority, but both interchanges had funding by August 1970.

Nordahl Road was also improved, and extra lanes were to be added between Nordahl Road and I-15; construction commenced in early 2012, and the new bridge opened in November. The project cost $ 41 million.
