Vincent Thomas Bridge Deck Replacement Updates

The VTB Deck Placement Project

The Vincent Thomas Bridge Deck Replacement Project is a Caltrans-led infrastructure initiative that will begin in November 2026 to replace the bridge deck and modernize key structural components. The Vincent Thomas Bridge is located in Los Angeles Harbor, connecting the communities of San Pedro and Terminal Island via State Route 47, and serves as one of three access point for port operations. The project will require a temporary 16-month closure of State Route 47 across the bridge. This investment is designed to enhance the long-term safety, reliability, and resilience of one of the primary transportation links serving the San Pedro Bay port complex.

What does this mean for the Port Complex

Throughout the duration of the bridge closure, all Port of Los Angeles and Port of Long Beach facilities will remain fully open and operational. Of the roughly 53,000 daily crossings on the Vincent Thomas Bridge, approximately 4500 or 8% are port related trucks, meaning the majority of port cargo flows will continue unaffected during the closure. There is no expected impact on cargo terminal capacity, or rail operations within the port complex. While localized detours may modestly affect some truck routes, the movement of goods through San Pedro Bay will continue uninterrupted, ensuring the Port remains a reliable gateway for national and global trade and maintaining supply chain continuity despite the temporary loss of this roadway connection.

Schedule of the closure and pre-closure projects

The Vincent Thomas Bridge Deck Replacement Project is scheduled to begin in November 2026 and will require an approximately 16-month closure of State Route 47 across the bridge and is anticipated to reopen in March 2028. Updates and milestone information will be shared regularly through Port of Los Angeles and Caltrans communication channels.

Alternative and Detour routes

Caltrans, in coordination with regional partners, has developed a comprehensive Traffic Management Plan to support the temporary closure of State Route 47 during the bridge deck replacement project. Clearly marked and widely communicated detour routes will be implemented to help maintain efficient traffic flow throughout the San Pedro Bay area. The plan includes enhanced traffic control measures, deployment of enforcement officers, and adjusted signal timing to minimize congestion and support safe, reliable access to port facilities. These proactive measures are designed to reduce disruptions and ensure continued connectivity for commercial vehicles, local businesses, and surrounding communities.
