Seamless HOV Connection

The West County Connectors Project was initiated by the Orange County Transportation Authority (OCTA) and Caltrans to link HOV (carpool) lanes on the San Diego Freeway (I-405), the Garden Grove Freeway (SR-22) and San Gabriel River Freeway (I-605) to create a seamless HOV connection among the three freeways. Spanning the cities of Garden Grove, Westminster, Seal Beach, Los Alamitos, Long Beach and the community of Rossmoor, the project will:

  • Construct two direct HOV connectors
  • Add a second HOV lane in each direction on I-405 between the SR-22 and the I-605
  • Reconstruct the Valley View Street bridge (over SR-22)
  • Reconstruct the Seal Beach Boulevard bridge
  • Reconstruct the Northbound I-405/Westbound SR-22/7th Street connector
  • Reconstruct on- and off-ramps
  • Construct soundwalls and retaining walls at various locations
  • Add landscaping and enhance aesthetic elements

Psomas was contracted by Parsons to provide survey, mapping and right-of-way engineering services in support of the PS&E for this project. As a subconsultant to CALTROP, Psomas is currently providing construction staking for all improvements associated with this OCTA Measure M freeway expansion project.
