Replacement Planting Project

OCTA is working with Caltrans to coordinate plans for an upcoming Replacement Planting Project, with construction estimated to begin in August 2015. The objective of this project is to provide replacement planting to areas affected by the WCC roadway construction. The project will utilize native, drought-resistant trees and vines selected from a list of species approved by Caltrans, which will oversee the replacement planting.

If you have questions prior to the start of construction, please email, or call OCTA Community Relations Officer Chris Boucly at (714) 560-5326. If you have questions once construction starts, please contact Caltrans District 12 Public Information Officer David Richardson at (949) 724-2341 or

Again, our team would like to thank you for your patience during construction. Please take a moment to visit and fill out a survey to help our team improve communication efforts for future projects.

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.
