Per WMATA: As people across the region prepare to celebrate the Independence Day holiday, Metro is also preparing to get people to and from July Fourth activities and fireworks. Trains will operate regular weekday service on all lines, with supplemental service on the Red Line and trains positioned throughout the system to provide extra capacity when needed.
Downtown where stations are served by multiple lines, as well as the Red Line, trains will arrive every 6-8 minutes. Off-peak fares will be in effect and parking will be free at all Metro parking facilities and garages.
