Project Website

Working to improve traffic capacity and operations on I-15, RCTC and Caltrans District 8 are exploring widening I-15 from just north of the 15/215 separation near Murrieta, to SR-60 near Ontario.  Environmental and feasibility studies and preliminary engineering are underway. Concepts being studied include the addition of regular, tolled express, and carpool lanes at various locations throughout this 44 mile corridor. A fuller understanding of the project alternatives are anticipated as these studies progress. The following project elements are being studied:

French Valley Parkway Interchange (Phase 1)

  • Construct a new southbound off-ramp from I-15 to French Valley Parkway
  • Construct the western segment of French Valley Parkway from the off-ramp to Jefferson Avenue
  • Widen the I-15 southbound off-ramp to Winchester Road (SR-79 North)
