Interstate 15 / SR - 74 Central Avenue Interchange Project

The Project

The City of Lake Elsinore (City), in cooperation with the California Department of Transportation (Caltrans), is proposing improvements to the Interstate 15 (I-15)/State Route 74 (SR-74) (Central Avenue) interchange located in the City of Lake Elsinore, California. The I-15/SR-74 Interchange Improvement Project is needed to improve traffic conditions, reduce congestion at the interchange, and help alleviate traffic at surrounding local intersections within the Project area. Visit the project’s Interactive StoryMap at for more details.

Project Goals

  • Support anticipated regional growth and local development projects.
  • Relieve congestion by providing additional ramp storage capacity and directional connectivity between I-15 and SR-74.
  • Improve operational efficiency of signalized intersections, turning movements, and throughput volumes.
  • Improve mobility and access for all users, residents, and businesses within the Project limits.

Estimated Construction Cost: $39 Million
