Project Overview

The Port of Los Angeles and California Department of Transportation (Caltrans) began work in March 2024 on a $130 million transportation project to reconfigure a major interchange at State Route 47/Vincent Thomas Bridge and Front Street/Harbor Boulevard in San Pedro.
This interchange currently provides access to San Pedro, Wilmington, Terminal Island and services the West Basin Container Terminal. The reconfiguration will reduce travel times, alleviate congestion and improve motorist and pedestrian safety at this highly traveled roadway juncture.
The reconfiguration will replace an existing southbound SR 47 off-ramp from the Vincent Thomas Bridge, currently located on the south side, with a new off-ramp located on the north side. Additional improvements include realigning the existing on-ramp to northbound I-110 connector; modifying the northbound SR 47 off-ramp onto Harbor Boulevard; and modifying the northbound SR 47 on-ramp onto the bridge toward Terminal Island.
The SR 47 Interchange Project addresses traffic connections in San Pedro that access the Vincent Thomas Bridge, not the bridge itself.
In a separate project, Caltrans is proposing the VTB Deck Replacement Project to replace the entire bridge deck and seismic sensors of the bridge to preserve the functionality and structural integrity of the Vincent Thomas Bridge deck and to enhance the bridge's overall safety.
