Project

The Vincent Thomas Bridge (VTB) was built in 1963 and has been in service for 60 years. Although the bridge is structurally sound, the bridge deck is rapidly deteriorating. This is due to concrete fatigue caused by heavy traffic loading, as well as environmental deterioration due to age and the marine environment. Caltrans is proposing to replace the entire bridge deck and its seismic sensors. In addition, the project will replace the bridge railings, fences and median barrier. The purpose of this project is to preserve the operations, functionality, and structural integrity of the bridge deck.

Benefits

Caltrans aims to replace the bridge deck and modernize other bridge components, which is needed to enhance the safety of the traveling public on the VTB and maintain an important economic corridor to Terminal Island.

Schedule

Construction is expected to begin in late 2025, with the bridge closing in fall 2026 and reopening before the 2028 Olympic Games. Key project milestones and the schedule are shown below:

*PA/ED: Project Approval and Environmental Document

**Nightly one directional closures and possible weekend closures

*** Full closure (16 months)

Cost

The estimated cost for the Vincent Thomas Bridge Deck Replacement project is about $706 million.
