Avenida Pico to San Juan Creek Road

This project was completed in 2018.

The completion of a new carpool lane and improvements to the Avenida Pico Interchange, the I-5 South County Improvements Project is complete. This 5.7 mile project, a partnership between OCTA and Caltrans, extended the carpool lane in each direction of I-5 from between its prior terminus in San Juan Capistrano and San Clemente. The project also reconstructed the Avenida Pico interchange, adding dual left-turn lanes to both on-ramps and widening the northbound on-ramp to three lanes.
