I-5 HOV Extension and Pico Interchange

This $275 million Caltrans project will widen the I-5 freeway to extend the existing carpool (HOV) lane from San Juan Creek Road in San Juan Capistrano to just south of Avenida Pico in San Clemente. The project also includes complete reconstruction of the I-5 / Pico interchange. All three segments are under construction, and the last phase of the project is expected to be completed in late 2017.
