Station Construction

Underground rail stations are an essential part to many of Metro’s existing and upcoming rail projects. Please see the Tunneling Fact Sheet to learn how decisions are made whether to build underground and how tunnels are built.

Current and Future Below Ground Rail Stations

Metro currently has underground stations on the following lines:

  • Metro A Line (Blue): The northernmost station at 7th St/Metro Center in downtown Los Angeles is below ground. Opened 1990.
  • Metro B/D Line (Red/Purple): Sixteen fully underground stations from Union Station to North Hollywood and Wilshire/Western Stations. Opened in phases 1993-2000.
  • Metro L Line (Gold): Two fully underground stations at Mariachi Plaza and Soto. Opened in phases 2003 and 2016.
  • Metro E Line (Expo): Like the A Line, this line comes into the 7th St/Metro Center Station in downtown Los Angeles below ground. Opened in 2012.

In addition, Metro currently has three projects under construction that incorporate underground stations:

  • Metro Crenshaw/LAX Transit Project: Includes three underground stations – the Expo/Crenshaw, Martin Luther King Jr. and Leimert Park Stations.
  • Metro Regional Connector: Has a fully underground alignment with stations at Little Tokyo/Arts District, Historic Broadway and Grand Ave/Bunker Hill, and will connect to the existing 7th Street/Metro Center Station.
  • Metro Purple (D Line) Extention Transit Project: Like the current D Line, the Extension is fully underground. Connecting at the existing Wilshire/Western Station, it adds stations at Wilshire/La Brea, Wilshire/Fairfax, Wilshire/ La Cienega, Wilshire/Rodeo, Century City/Constellation, Westwood/UCLA and Westwood/VA Hospital.

Construction Overview

Construction at each station is estimated to take five to seven years. Underground stations are constructed from the surface by excavating the area to be occupied by the station box. Construction staging areas are usually located immediately adjacent to station construction sites. It is preferable to utilize two staging areas directly adjacent to each station construction area to expedite the process.
