On June 16, 2025, the City of Temecula, RCTC, and project partners gathered to celebrate the completion of Phase 2 of the French Valley Parkway Improvements Project.

The I-15/215 junction serves as a vital connection for Riverside County and the greater southern California region. This junction connects travelers from San Diego and beyond and is a vital lifeline for residents of Temecula and Murrieta. As southwest Riverside County continues to grow, the I-15 corridor and ramps have become increasingly congested, but relief is on the way.

Phase 2 of the French Valley Parkway Project addresses a major traffic bottleneck on northbound I-15 between Winchester Road and I-15/215 by constructing a concrete barrier to separate highway and on-ramp traffic. It features new dedicated ramps for motorists entering northbound I-15, including a new bridge overpass for direct access to I-215, which eliminates troublesome merging and weaving.

For nearly 20 years, RCTC prioritized funding for the French Valley Parkway Project, recognizing the project’s pivotal role in alleviating congestion in the region. RCTC allocated $47 million in State Transportation Improvement Program (STIP) funding for this project, one of the largest such allocations for a project.

Looking to the future, Phase 3 of the French Valley Parkway Project is a cornerstone of RCTC’s Traffic Relief Plan – a regionwide transportation improvement blueprint aimed at enhancing mobility across Riverside County. Partners in the region are working to start construction on future phases of French Valley Parkway to further alleviate traffic congestion. Phase 3 includes construction of the full-width of French Valley Parkway between Jefferson Avenue and Ynez Road, including the bridge overcrossing of I-15, and connecting on-ramps to the new dedicated on-ramps constructed in Phase 2. Phase 4 will construct a new northbound off-ramp and southbound on-ramps for the French Valley Parkway interchange, and new dedicated ramps along southbound I-15.

RCTC is also working on additional improvements along the I-15 Corridor in Temecula and Murrieta with the construction of the I-15 Smart Freeway Pilot Project – a first of its kind in California. Completion of Phase 2 of the French Valley Parkway Improvements Project, along with planned future improvements along this busy corridor, demonstrate how local and regional agencies are working collaboratively to improve Riverside County mobility for all residents.

The Riverside County Transportation Commission congratulates our partner in transportation solutions the City of Temecula, on receiving $50 million in federal grant funds for the Interstate 15 French Valley Parkway interchange.

Representative Ken Calvert, CA-42, was instrumental in securing funding for the interchange, a project in his district, through the Infrastructure for Rebuilding America grant program administered by the United States Department of Transportation. Temecula was one of only twenty grant recipients in the entire nation.

“Our regional economy depends upon our transportation network, which is severely congested,” said RCTC Chair and Riverside County Supervisor Chuck Washington. “Thanks to the continued efforts of Congressman Calvert and the U.S. Department of Transportation, the City of Temecula is one giant step closer to traffic relief in southwest Riverside County.”

Temecula’s grant demonstrates the success of partners working together.  The City is working closely with Caltrans, RCTC, neighboring cities, the business community, and many others to address congestion on I-15.  RCTC has programmed $47.6 million in state funds for the French Valley Parkway Interchange.

“Traffic doesn’t heed city or county lines, so bringing funding to anywhere in Riverside County is a victory for all residents,” Washington added.  “Our county must work together to secure as many transportation funds as possible. This is a big win for our region.”

The grant funds will allow the City of Temecula to complete the next phase of the French Valley Parkway interchange with Interstate 15. The project is designed to reduce traffic weaving as motorists drive northbound and southbound on I-15, especially at the 15/215 ‘Y’ interchange.

The interchange has been a priority for RCTC for many years and the Commission included the next phase of the project in its 2019-2029 Western County Highway Delivery Plan. RCTC prides itself in working will our transportation partners in solving traffic issues for our residents.  It is our mission.
