15 Express Lanes Project Facts


The Riverside County Transportation Commission (RCTC) and its project partners, the California Department
of Transportation and the Federal Highway Administration, are investing $471 million to improve Interstate 15.
The project will add two express lanes to I-15 in both directions, from Cajalco Road to State Route 60, widen
bridges and add soundwalls. This design-build project will be built within the existing median and offer multiple entry and exit points to the express lanes.


  • Improve existing and future mobility along the I-15 corridor
  • Reduce congestion and improve traffic operations
  • Provide a time-saving travel choice with multiple entry / exit points
  • Expand the tolled express lane network
  • Increase travel time reliability


RCTC is proceeding with a design-build process to expedite delivery of the project and minimize construction costs.
