I-15 / French Valley Parkway Improvements

Map of French Valley Parkway Interchange


Reduce congestion and improve safety by relieving the I-15/Winchester Road interchange and minimizing weaving movements on I-15 between Winchester Road and the I-15/I-215 Junction.


  • A new arterial, French Valley Parkway, connecting Jefferson Avenue and Ynez Road
  • A new interchange connecting French Valley Parkway to I-15
  • A new collector/distributor system along I-15 between Winchester Road and the I-15/I-215 Junction
  • Modifications to the I-15/Winchester Road interchange such as ramp widening for additional lanes

Phase 2 - Under Construction May 2023 to May 2025

Shown in blue on aerial map. This phase targets the bottle-neck on northbound I-15 between Winchester Road and the I-15/I-215 Junction.  In this area, the large volumes of vehicles attempting to merge and diverge across 4 to 5 lanes creates a hotspot of congestion and results in back ups into San Diego County ranging from 3 to 12 miles every weekday and on many weekends.  This phase will eliminate the merging and diverging by installing a concrete barrier and bridge overpass to separate streams of traffic and channelize them based on ultimate destination.  These improvements are designed to drastically reduce congestion that occurs during the evening commute.

PHASE 2 Video Playlist:  French Valley Parkway Interchange Project

Phase 1 - Opened in April 2014

Shown in red on aerial map. Construction was completed in 2014.  This Phase targeted the delays at the southbound exit for Winchester Road.  Prior to construction, the line of cars would extend onto the freeway and back towards the I15/I215 Junction.  This project widened the off-ramp at Winchester Road and created a new off-ramp at French Valley Parkway.  By increasing capacity of the Winchester Road off-ramp and adding an alternative off-ramp at French Valley Parkway, vehicles can more easily exit the freeway and traffic flow on the freeway is improved and safer.
