I-5 South County Improvements Project

The I-5 South County Improvements Project is a significant infrastructure initiative aimed at enhancing a 6.5-mile stretch of Interstate 5 in Orange County, California. This project focuses on the segment between State Route 73 and El Toro Road, traversing the cities of Mission Viejo, Laguna Niguel, Laguna Hills, and Lake Forest. 

With an estimated budget of $664 million, the project commenced in June 2019 and is anticipated to reach completion by early 2025. 

Project Objectives and Scope

The primary goal of the I-5 South County Improvements Project is to alleviate traffic congestion and improve the overall flow on one of Southern California’s most heavily traveled freeway sections. Key components of the project include:​

• Lane Additions: Introducing an additional general-purpose lane in both northbound and southbound directions to accommodate increasing traffic volumes.​
• Interchange Enhancements: Upgrading interchanges within the project limits to improve traffic movement and safety.​
• Bridge Replacements and Modifications: Reconstructing and widening bridges to support the expanded freeway capacity and ensure structural integrity.​
• Operational Improvements: Implementing measures such as improved signage, lighting, and drainage systems to enhance driver experience and roadway safety.​

Funding and Collaboration

The project is a collaborative effort between the Orange County Transportation Authority and the California Department of Transportation. Funding is sourced from a combination of federal funds and Measure M, Orange County’s half-cent sales tax dedicated to transportation projects. ​

Construction Phases and Updates

Construction activities have been strategically phased to minimize disruptions to motorists and local communities. Regular updates on closures, detours, and project milestones are provided to keep the public informed. As of mid-2024, approximately $655 million has been expended, with the project on track for its early 2025 completion target. ​

Community Impact and Benefits

Upon completion, the I-5 South County Improvements Project is expected to deliver several benefits:​

• Reduced Congestion: The additional lanes and upgraded interchanges will facilitate smoother traffic flow, reducing travel times for commuters and freight transport.​
• Enhanced Safety: Modernized infrastructure, including improved bridge structures and operational features, will contribute to a safer driving environment.​
• Economic Growth: Improved transportation efficiency can stimulate local economies by attracting businesses and facilitating commerce.​
