revenue. The project included building a second bridge over the San Luis Rey River. Discussion on whether the route of the highway should go south or north of the river east of Mission Road began later that year, with residents expressing concerns about being able to make left turns. In June 2011, Caltrans decided to use the existing roadway as the path, but agreed to build traffic signals at Via Monserate, South Mission Road, Gird Road, and Old Highway 395. For environmental mitigation, Caltrans purchased the parcel known as Rancho Lilac, which was . The second Bonsall bridge was finished by April 2012. The westbound lanes between Melrose Drive and Mission Road opened to traffic in October, with the entire roadway projected to be complete by the end of the year. The total cost of the entire widening project east of Melrose Drive is projected to be $371 million. A request by the city of Oceanside to restore access to Jefferies Ranch Road from SR 76 was declined by Caltrans in late 2012, due to concerns about future expressway expansion to six lanes. In May 2013, construction at the I-15 and SR 76 interchange uncovered a Bison latifrons fossil. Revisions to the interchange were finished in August 2013. The final portion east to I-15 was contracted out in August, and construction was to begin soon afterward and extend until 2017, at a cost of $201 million. In August 2016, traffic was to switch from the existing roadway to the newly constructed one west of I-15, from Gird Road to Old Highway 395. This would allow the older roadway to be reconfigured to carry westbound traffic, while the new roadway would handle eastbound traffic. The new roadway was described as having fewer turns than the older road, which would increase safety. The expansion of the road to four lanes was completed in May 2017; this meant that from about east of the interchange with I-15 west to CR S21 the roadway was four lanes wide, including the widening that had been paid for by the owners of a rock quarry.
