This 15.2-mile light rail line Design-Build project utilizes the exposition corridor with 19 stations. Phase II includes seven new stations along the Westside. The Exposition Light Rail Transit (LRT) to Santa Monica is a significant and long-term public investment in transit, city-wide and regional mobility and sustainability.
Group Delta, an NV5 company, provided materials evaluation of 1920’s brick arch tunnel under light railroad and geotechnical recommendations for Exposition Light Rail Transit (LRT) stations over Sepulveda Boulevard. and Centinela. Services also included Multiple Mechanical Stabilized Earth (MSE) light.
Added Value
- Historic Structure Evaluation: Our team conducted materials evaluation of a 1920s brick arch tunnel located beneath the light rail alignment, ensuring structural integrity and compatibility with modern transit loads.
- Geotechnical Design Support: Our team provided geotechnical recommendations for LRT station construction over key corridors, including Sepulveda Boulevard and Centinela Avenue, addressing complex subsurface conditions.
- Earth Retention Solutions: Our team delivered engineering support for multiple Mechanically Stabilized Earth (MSE) walls, contributing to safe and efficient station and trackway construction.
