Red shows the proposed Phase 1 proof-of-process tunnel for which The Boring Company has filed an excavation permit application. Phase 1 would include the construction of a 2.7-mile proof-of-process tunnel through Los Angeles and Culver City. The tunnel would be used for construction logistics verification, system testing, safety testing, operating procedure verification, and line-switching demonstrations. Phase 1 would not be utilized for public transportation until the proof-of-process tunnel is deemed successful by County government, City government, and TBC.
Blue indicates potential Phase 2 expansion options, and is included as a concept, not as a finalized alignment. Phase 2 specifics would be developed in cooperation with Los Angeles County, the City of Los Angeles, city governments in the greater Los Angeles area, and the general public. The Boring Company looks forward to receiving feedback from residents of the greater Los Angeles area on station locations and system improvements for Phase 2 and beyond.
