While not funded or managed by OCTA, the Santa Ana Freeway
(I-5) South Corridor Improvement Project may impact Orange County commuters and
travelers on the I-5. This page provides general background and relevant links
to the main project pages.
Caltrans is investing $1.6 billion dollars in the Santa Ana Freeway (I-5) South Corridor Improvement Projects to improve southern segments along the Santa Ana Freeway (1-5) between the Orange County/Los Angeles County line and the San Gabriel River Freeway (I-605). Major improvements include widening the freeway, upgrading bridges and overcrossings, and adding one High Occupancy Vehicle (HOV) lane and one general purpose lane. The improvements will enhance safety, improve traffic flow, reduce congestion, encourage ridesharing, decrease surface street traffic and improve air quality.
Construction is expected to continue through early 2016.
Detours will be posted and digital portable message signs are in place to notify the motorists. Residents and emergency responders will have access at all times during the closure. Noise will be experienced from back-up alarms, work crews and other related equipment and water trucks will be on-site and used to minimize dust during working.
The public is encouraged to sign-up to receive email notifications on freeway lane and ramp closures and local city street closures by calling the I-5 South Corridor Improvement Projects Toll-Free Hotline (855) 454-6335 or by visiting http://www.my5la.com/
