Metro will run extra trains during the evening of July 4 to help passengers get to and from the National Mall for the fireworks display.
The system will run on a weekend schedule, opening at 7 a.m. instead of 5 a.m., on Thursday. It will stay open until midnight. Trains between 6 p.m. and midnight will operate at near rush-hour service levels.
More than 500,000 people are expected to take Metro on Independence Day, WMATA said.
Riders should try to use stations other than Smithsonian or Federal Triangle, which often see the heaviest ridership for National Mall events, the transit agency said. The Smithsonian station will be “entry-only” at the end of the fireworks event.
Metro offers a list of alternative station choices on its website.
There will be no scheduled track work over the holiday.
