West County Connectors

WCC Project Milestones

  • Southbound I-605 to southbound I-405 carpool connector - Open
  • Northbound I-405 to northbound I-605 carpool connector - Open
  • Westbound SR-22 to northbound I-405 carpool connector - Open
  • Southbound I-405 to eastbound SR-22 carpool connector – Open
With the HOV connectors now open, freeway closures are anticipated to occur intermittently through February 2015. These anticipated intermittent nighttime closures are needed for crews to conduct clean-up activities and de-mobilize their equipment throughout the project area.

Project Overview

wcc logo

The West County Connectors project is a joint partnership between OCTA and Caltrans linking high occupancy vehicle (HOV) lanes/carpool lanes on the San Diego Freeway (I-405) with those on the Garden Grove Freeway (SR-22) and San Gabriel River Freeway (I-605) to create a seamless carpool connection amongst the three freeways. The 6-mile project traverses the cities of Garden Grove, Westminster, Seal Beach, Los Alamitos, Long Beach and the community of Rossmoor. 

Project Improvements Include

  • Constructing two direct carpool connectors
  • Adding a second carpool lane in each direction on the I-405 between the SR-22 and the I-605
  • Reconstructing on- and off-ramps
  • Constructing soundwalls and retaining walls
  • Adding landscaping and enhancing aesthetic elements

Completion of the carpool connectors marks just one of the major milestones achieved over the last four years. This infographic highlights a few of the exciting milestones the WCC project team has celebrated since the project began in 2010.

Catch a glimpse of what the project area will look like upon completion of the WCC project.

The project is split into two segments – east and west segments.

EAST SEGMENT: SR-22/I-405 Carpool Connector

  • Directly connect the westbound SR-22 carpool lane at Valley View Street to the carpool lane on the northbound I-405 and the reverse movement
  • Reconstruct southbound I-405 to eastbound SR-22 connector
  • Reconstruct the Valley View Street Bridge over the SR-22

SR22/1-405 Connector

WEST SEGMENT: I-405/I-605 Carpool Connector

  • Directly connect the northbound I-405 carpool lane to the carpool lane on the northbound I-605 and the reverse movement.
  • Reconstruct the Seal Beach Boulevard bridge over I-405. Click for more information.
  • Reconstruct the eastbound SR-22 to the northbound I-405 connector.
  • Reconstruct the eastbound SR-22 to the northbound I-605 connector.
  • Reconstruct the northbound I-405 to the westbound SR-22 connector /7th St.
