Skanska has highlighted four civil infrastructure projects in Southern California that are improving transportation connections, flood protection and community resilience. The projects include emergency retaining wall repairs in Los Angeles, a railroad grade separation in the City of Industry, levee rehabilitation in Riverside and interchange improvements near the Port of Los Angeles.
In an update dated September 18, 2026, the company outlined completed work and upcoming milestones across the projects, which are intended to strengthen regional infrastructure and support communities.
Following the Pacific Palisades fire, Skanska’s team repaired a 900-foot beam-and-lagging retaining wall near the Getty Villa along Pacific Coast Highway. The work involved removing soil and debris, replacing damaged lagging, removing temporary steel plates and applying specialised fireproofing paint developed through collaboration between Caltrans and the University of California, Berkeley.
In the City of Industry, the Fullerton Road Grade Separation project is designed to separate road traffic from a busy Union Pacific Railroad crossing. The work includes lowering the roadway, raising the railroad right-of-way and installing pumping systems to manage groundwater conditions. Approximately 90 trains travel through the corridor daily.
The project is expected to improve transportation safety, reduce delays and support the movement of freight and passenger vehicles. Skanska reported that the team was targeting an opening in 2026.
The Riverside Levees Rehabilitation project restored sections of the Santa Ana River levee system between Market Street and Mission Street. Work included excavation, toe-fill placement, riprap removal and salvage, and temporary sound barrier construction.
The project involved approximately 328,000 cubic yards of excavation, 331,000 cubic yards of toe fill and the removal and salvage of 200,000 cubic yards of riprap. GPS-guided equipment and improved field technology helped crews complete the construction work one year ahead of schedule.
Near the Port of Los Angeles in San Pedro, the SR-47 Vincent Thomas Bridge and Front Street/Harbor Boulevard Interchange Reconfiguration project is upgrading access to the bridge and surrounding transportation network.
The work includes replacing and realigning five ramps, realigning Knoll Drive, upgrading Front Street and Harbor Boulevard, and improving drainage, lighting and traffic signals. Additional features include bike lanes and Americans with Disabilities Act-compliant infrastructure.
Together, the four projects address infrastructure resilience, road safety, flood protection and freight mobility across Southern California.
