The reason: more work on the junction of the Blue Line and future Expo Line. Here’s the news release:
Due to continued construction work for the new Expo Line in the downtown Los Angeles area, service on the Metro Blue line will be replaced with bus shuttles on Sunday, Nov. 20.
Expo construction crews will continue their work integrating the Expo Line rail system into the existing Metro Blue Line system that will necessitate the closure of the downtown Los Angeles segment of the Metro Blue Line and the use of buses to transport Metro Blue Line passengers between the Washington Station and 7th/Metro Center Station.
No Metro Blue Lines trains will operate between the 7th Street/Metro Center Station and the Washington Station on Sunday, Nov. 20. Metro Blue Line trains will operate on normal schedules from the Washington Station to Long Beach. Patrons are advised to allow up to 40 additional minutes to complete their trip. Normal Metro Blue Line service will resume with the start of morning service on Monday, Nov. 21.
Stations impacted due to the partial Blue Line closure include 7th Street Metro Center, Pico, Grand and San Pedro. For specific route and schedule information visit metro.net.
