Getting There: Both Metro and Metrolink will expand service on Saturday to accommodate the crowd expected to attend.
- Using Metro: The closest station is Pershing Square. Metro urged people to arrive early and consider buying TAP cards and loading them with adequate fare in advance to avoid what are likely to be long lines at TAP kiosks on Saturday. Metro plans to bolster service on its rail lines from 6 a.m. to 7 p.m. Saturday. Service will be increased on rail lines and on the Silver and Orange bus lines and on Metro Line 720. Some local Metro buses that typically travel through downtown could be diverted due to the crowds and street closures, and passengers were urged to consider exiting before reaching the downtown area.
- Using Metrolink: Metrolink also plans to boost service on its regional rail lines. Officials plan to add 12 trains through Southern California to accommodate crowds. Trains will be added on the San Bernardino and Antelope Valley lines. Metrolink will also offer service on its Ventura County line between Chatsworth and Los Angeles. The Ventura County line typically does not operate on weekends. You can buy tickets through the Metrolink app.
