This 5.7-mile project extends from Avenida Pico in San Clemente to San Juan Creek Road in San Juan Capistrano. The four-year, $249 million project will:
- Add a carpool lane in both directions on I-5 between Avenida Pico and San Juan Creek Road
- Improve the sight distance on the southbound horizontal curve north of PCH
- Reconstruct the interchange at Avenida Pico, including widening the northbound Avenida Pico on-ramp to three lanes, and provide dual left-turn lanes to both northbound and southbound Avenida Pico on-ramps
- Add soundwalls where needed
Nightly closures are plotted on a Google Map and includes specific closure times as well as recommended detours. Closures are updated in real time and can be accessed by clicking the image below or visiting www.octa.net/5southCountyDetourmap. This interactive map is easily accessible on your smart phone or you can bookmark the page on your computer and it allows you to see other local detour routes that may be convenient for your commute.
