SR 47 Interchange Project

Back

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. Work is set to begin in early 2026 with an anticipated closure of 16 months. Get more information on that project, here.

Traffic Advisories

The public will be kept updated on related traffic impacts with road signs throughout the duration of the SR 47 Interchange Project. Drivers should follow posted traffic signs accordingly.

If you have additional questions about these traffic impacts, please leave a message at (310) 732-7778 and your call will be returned within 24 hours.

Posted below are anticipated lane reductions, ramp closures and detour information.

Northbound I-110 On-Ramp Lane Reduction

The northbound I-110 on-ramp from Harbor Boulevard/Front Street reduced to a single lane for approximately one year.

New Traffic Pattern on Front Street/Knoll Drive

A new lane configuration implemented on Knoll Drive, resulting in lane reductions between the Front Street intersections for approximately nine months.
