I-5/Ortega Highway Interchange Improvement Project
This project was completed in 2015.
Caltrans District 12 reconstructed the Ortega Highway interchange at the
I-5 freeway in San Juan Capistrano. Construction began in February 2013 and was completed in
late 2015. The work included widening the Ortega Highway Bridge, reconstructing on- and
off-ramps, constructing a new northbound I-5 loop on-ramp from eastbound Ortega Highway as
well as realigning the Ortega Highway interchange. The project was initiated by Caltrans,
OCTA and the City of San Juan Capistrano, as the solution to the "choke point", where
significant delays and congestion occur along the Ortega Highway (SR-74) at the San Diego
Freeway (I-5) interchange.
