OC I-5 South County

Ave. De La Carlota will be reduced to two lanes by Laguna Hills Mall for about mile as crews realign and reconstruct one of the project’s longest retaining walls. Motorists will still be able to access the area's office buildings and residential complexes as well as shops, restaurants and boutiques.

Two major retaining walls are nearly complete on northbound I-5 between La Paz Road and Alicia Parkway. The new walls feature a pastoral ranch and slate stone aesthetic. #southcounty #southoc #i5progress #goocta #lapaz #orangecounty #ocgo

As part of south Orange County’s I-5 Widening Project, crews recently constructed temporary on and off-ramps at Alicia Parkway. Motorists are encouraged to drive safely through the area, adhering to traffic regulations and posted signage.

Everyone loves a good time lapse! The new northbound La Paz Road loop on-ramp bridge deck is now in its final position. This ramp will open to motorists Spring 2022. Next up: crews will be paving along the northbound I-5 straight on-ramp from La Paz Road.

Don’t forget! The speed limit has been reduced to 55mph throughout the project area for the safety of crews and motorists. Traffic fines may be doubled in a construction zone.

The Aliso Creek Bikeway and Aliso Creek Riding & Hiking Trail is temporarily closed through spring 2022 because of the I-5 South County Improvements Project. This closure, to the east and west of I-5, allows crews to widen the freeway bridge over the Aliso Creek Bikeway. A detour provides cyclists access around the closed section of the Aliso Creek Bikeway and Aliso Creek Riding & Hiking Trail near I-5.

The northbound I-5 off- and on-ramps at Avery Pkwy. and right two lanes on northbound I-5 will be closed nightly. There will be no access on Avery Pkwy. under the I-5 bridge.
