Wall Innovations Utilized in the Mid-Coast Trolley and LOSSAN Corridor Rail Projects

The LOSSAN (Los Angeles to San Diego) rail corridor is the second busiest intercity rail corridor in the nation supporting commuter, intercity, and freight rail services. The San Diego LOSSAN rail improvements and Mid-Coast Trolley projects include adding 3 new rail lines.  One heavy rail for Amtrak, Union Pacific and BNSF heavy rail freight services, and two light rail tracks for commuter trains for a total of 4 tracks along the corridor. 

Several traditional retaining walls planned for the project were replaced with Precast Concrete Counterfort Walls, which have been around for over 40 years, but are recently becoming more popular because of their cost savings, speed of construction, strength and diverse aesthetic options.  The presentation will provide information on five large precast counterfort retaining walls that were designed and constructed for the project, including some of the design challenges, and potential future research that can be done to further verify and possibly improve the design.
