CTF - Freeway/Expressway Project of the Year




Adding Four Lanes over Two Miles

The I-5 Gateway Project is the final phase in Orange County’s ambitious freeway improvement program. This four-year project involved increasing the traffic capacity of a two-mile portion of the existing six-lane freeway by adding a general traffic and an HOV lane in each direction from the 91-Freeway to the Los Angeles County line.

Psomas is providing construction staking for the freeway widening, reconstruction of four major bridges, relocation of railway rails and structures, relocation of major utilities and reconstruction of drainage structures.
