Musk had wanted to dig a 2.7-mile tunnel planned along Sepulveda Boulevard on L.A.'s Westside.

The Boring Company has posted images online showing a possible network of tunnel routes across L.A., with proposed stations at the Getty Center, Dodger Stadium, Union Station and Los Angeles International Airport. Opponents say that the map is evidence that the proposed Westside tunnel is part of a much larger planned underground transportation network. California does not allow portions of construction projects to be approved separately.

City Councilman Paul Koretz supports the tunnels. Koretz hopes Boring Company tunnels can be built more quickly and at a lower cost and at no government expense. He would like tunnels from LAX to Westwood to the Valley at a minimum by the 2028 Olympics.
