The California Department of Transportation (Caltrans) has announced a pavement rehabilitation project on State Route 23 from U.S. 101 in Thousand Oaks to State Route 118 in Moorpark, due to funds from Senate Bill 1 (SB 1), the Road Repair and Accountability Act of 2017.

The $91 million project, including construction capital and support costs, will replace pavement on the outer two lanes from U.S. 101 to State Route 118 to provide a service life of 40 years. The on- and off-ramps, connectors and adjacent shoulders also will be rehabilitated, and slabs will be replaced where needed on the inner main lane in both directions. Existing curbs ramps will be enhanced to comply with the Americans with Disabilities Act (ADA), guardrails and signal lights will be upgraded, and approach slabs and bridge rails will be replaced at select locations. The project will improve 46.7 lane miles to provide a safer and smoother ride for motorists.

The contractor is Security Paving Company, Inc., of Westlake Village, CA. The construction phase is scheduled to begin Monday, April 27, 2020, and be completed in fall 2023. Generally, three lanes in each direction will be open for traffic for the duration of the project. An auxiliary lane will be used to shift traffic patterns to perform pavement work. Some ramps will be subject to 55-hour closures and detours will be provided. Special provisions allow the contractor to close lanes or ramps for extended periods as needed.

Motorists can expect construction-related delays and are strongly encouraged to allow extra time to get to a destination. Caltrans also advises motorists to use alternate routes when necessary. Residents and businesses near the freeway may experience noise, vibrations and dust associated with construction activities.

More than 116,000 motorists per day use sections of the roadway to reach their destination, and more than 4,600 truckers per day use this segment of State Route 23. Nearly 4 percent of the trucks on the interstate have five-plus axles adding to the wear and tear on the roadway.

All work is subject to change due to traffic incidents, weather, availability of equipment and materials, and other construction-related issues. More information and updates on the project can be found at and on Twitter via @CaltransDist7. 

SB 1 LogoSB 1 provides an ongoing funding increase of approximately $1.8 billion annually for the maintenance and rehabilitation of the state highway system. SB 1 funds will enable Caltrans to fix more than 17,000 lane miles of pavement, 500 bridges and 55,000 culverts by 2027.

Caltrans is committed to conducting its business in a fully transparent manner and detailing its progress to the public. For complete details on SB 1, visit
