California Transportation Foundation - Project of the Year

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.
