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 March 2015. These nighttime closures are needed for crews to conduct clean-up activities, de-mobilize their equipment throughout the project area, and conduct reviews of the project signage, fencing and metal beam guard rails, among other final tasks.

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.

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.
