Abstract
The most technically complex aspect of the Los Angeles County Metropolitan Transportation Authority (LACMTA) Regional Connector Transit Corridor (RCTC) project in Downtown Los Angeles is the mined crossover cavern, the largest tunneled excavation contemplated in Los Angeles, to be constructed using sequential excavation methods (SEM).
