The Vincent Thomas Bridge will close to all traffic on November 1, 2026, for a 16-month deck replacement that severs the most direct road link between San Pedro and Terminal Island until about March 2028. Caltrans confirmed the start date in its March project announcement and restated it in construction updates through the summer.
Drivers, port workers, and cruise passengers who rely on the crossing should lock in alternate routes now and attend one of three October open houses where Caltrans staff will walk through detour maps and signal timing. Cruise travelers sailing out of San Pedro can compare access options in our LAX to San Pedro cruise port transit guide before choosing arrival times.
- Closure: Full closure of the Vincent Thomas Bridge on State Route 47 starts November 1, 2026 and runs about 16 months to March 2028.
- Open houses: October 1 in Wilmington, October 8 in San Pedro, and a virtual session on October 14, each from 6 to 8 p.m.
- Detour planning: Caltrans will present detour routes and a traffic management plan at the sessions, with enhanced traffic control and adjusted signal timing.
- Project scope: A 752.8 million dollar deck replacement by the Skanska-CEC Joint Venture, including seismic sensor upgrades.
- Port impact: All Port of Los Angeles terminals stay open, only 8 percent of port drayage truck traffic uses the bridge, and rail cargo is unaffected.
November 1 Brings a 16-Month Full Closure
The four-lane bridge that arches over the Main Channel of the Port of Los Angeles will shut completely on November 1 so crews can replace the entire roadway deck. The Caltrans District 7 construction announcement sets the full closure for November 1, 2026 and describes a 752.8 million dollar project spanning partial and full closures over two years.
The Port of Los Angeles places the full closure window from November 2026 to March 2028 and says the work also modernizes bridge components beyond the deck. The bridge opened in 1963 and its deck has been repaired many times, but state engineers say patching is no longer enough. A complete deck replacement is now required to preserve the structure.
Caltrans cautions that the schedule can shift with weather or operational needs, including dates, closure counts, and details. Drivers should check Caltrans QuickMap for current conditions before traveling near the work zone. The agency also reminds motorists to slow down and stay alert around construction areas.
Three October Open Houses Detail Detours
With the shutdown weeks away, Caltrans scheduled three evening sessions in October to explain the project status, the construction schedule, and the traffic plan. The Daily Breeze report on the meetings lists two in-person gatherings plus one online session, each running from 6 to 8 p.m.
The first session meets October 1 at the Wilmington Recreation Center at 325 N. Neptune Avenue. The second meets October 8 at the Peck Park Community Center at 560 N. Western Avenue in San Pedro. The virtual session follows on October 14 through a published webinar link, with dial-in numbers for listeners who join by phone.
Caltrans personnel will present the construction schedule, the detour routes, and the traffic management plan, along with steps to address construction impacts on nearby neighborhoods. Each event includes a question-and-answer period, and recordings will be posted online afterward for residents who cannot attend.
How San Pedro and Terminal Island Trips Change
The bridge is the key connector for San Pedro to Long Beach commuter traffic and for workers reaching Terminal Island, so the closure pushes those trips onto surrounding freeways and surface streets. State Route 47 links San Pedro and Long Beach with Terminal Island and connects to Interstate 110, State Route 103, and Interstate 710, which will absorb the diverted traffic.
Overnight directional closures earlier in 2026 already detoured westbound traffic from State Route 47 to Route 103 to Pacific Coast Highway to Route 110, a preview of the longer reroutes to come. Harry Bridges Boulevard in Wilmington received pavement work because it will serve as part of the designated detour network during the full closure. Travelers headed to the San Pedro waterfront will find the same access questions covered in our Los Angeles cruise port guide, which lays out terminal arrival routes.
Cruise and cargo operations continue through the work. The Port of Los Angeles project page states that every terminal remains open with no expected impact on productivity, flow, or capacity. Only 8 percent of port complex drayage truck traffic crosses the bridge, and the port expects local detours to add some extra time for those drivers rather than disrupt cargo movement.
752.8 Million Dollar Deck Replacement Behind the Shutdown
The project replaces the entire bridge deck and its seismic sensors to extend the life of a structure that carries heavy port traffic in a marine environment. Concrete fatigue and years of heavy use drove the decision, according to state transportation authorities. The Skanska-CEC Joint Venture serves as general contractor for the build.
Preparation work began in spring 2026 with overnight directional closures, an under-deck shield, work platforms, and crew staircases. Those overnight closures ran from 10:45 p.m. to 6:45 a.m. on weeknights between Ferry Street and Harbor Boulevard. The fall brings occasional overnight closures before the full shutdown starts.
Local roads around the detour routes are getting upgrades first, including resurfacing and a temporary traffic signal where detour traffic will pass. Caltrans frames this advance work as reducing the shock when the bridge closes. Residents near the detour corridors should expect heavier volumes and retimed signals for the duration.
A Second Bridge Could Follow Within a Decade
Beyond the deck project, port, city, and state officials are studying a far larger fix: an entirely new bridge beside the current one. Port of Los Angeles Executive Director Gene Seroka said the parallel bridge concept could finish perhaps 10 years from now, with the existing bridge staying open during that construction.
The driver is ship size. Commercial vessels keep growing, and the vertical clearance under the Vincent Thomas Bridge no longer fits the newest ships calling at the port. That research phase is still gathering consultant and design data, with costs expected to challenge every agency involved.
For now, the deck replacement is the certain event and the new bridge is only a study. Travelers should plan around the 16-month closure dates rather than the decade-scale concept. The open houses will separate funded construction facts from longer-range ideas.
| If you… | What to do |
|---|---|
| Commute between San Pedro and Terminal Island | Build a new route via Interstate 110, State Route 103, or Pacific Coast Highway before November 1. |
| Sail from the San Pedro cruise port | Add an arrival buffer for closure traffic starting November 1, and review terminal driving directions the night before you travel. |
| Haul port cargo across the bridge | Expect local detours with extra travel time, since 8 percent of port drayage traffic uses the crossing, and confirm dispatch routing for November shifts. |
| Can shift your travel dates | Complete bridge-dependent trips before November 1 or travel outside peak hours, and monitor Caltrans QuickMap for overnight work before the full closure. |
October 1 through 14 is the briefing window. Attend the Wilmington, San Pedro, or virtual session to get the detour routes and signal timing before the closure starts.
November 1 is the closure gate. After this date the bridge is fully shut, so every San Pedro to Terminal Island trip needs its alternate route in place.
March 2028 is the reopening target. Caltrans expects the bridge back before the 2028 Olympic Games, but weather and operations can move the date, so recheck closer to arrival.
When does the Vincent Thomas Bridge close and reopen?
The full closure starts November 1, 2026 and is expected to last 16 months to about March 2028. Dates can shift with weather or operational needs.
Which detour should San Pedro to Long Beach drivers use?
State Route 47 connects to Interstate 110, State Route 103, and Interstate 710, and earlier overnight work detoured traffic through Route 103 to Pacific Coast Highway to Route 110. Get the final full-closure routing at an October open house.
Do the October open houses require registration?
The published meeting details list no registration step, only venues, times, and the virtual join information. Confirm the details on the Caltrans District 7 project page before you go, since advisories can change.
Will cruise ships and port terminals operate during the closure?
Yes. All Port of Los Angeles terminals remain open with no expected impact on operations, and only 8 percent of port drayage truck traffic uses the bridge. Allow extra driving time to reach the San Pedro waterfront.
Is the 16-month schedule firm?
Caltrans calls the schedule subject to change for weather or operational factors. Check Caltrans QuickMap before traveling and watch for updated advisories as November 1 approaches.
