Half a million people turn out every year for the July 4 fireworks in the District.
Metro will be running extra trains Thursday evening to help people get to and from the National Mall for the July 4th fireworks display.
Metro says more than 500,000 people are expected to use the transit system on Independence Day, with many traveling to the mall for the fireworks set to begin at 9:10 p.m.
Since most travel is expected late in the day, Metro will begin the holiday on a weekend schedule, opening at 7 a.m. Thursday instead of 5 a.m. But from 6 p.m. through closing at midnight, trains will operate at near rush-hour service levels.
To avoid crowding, Metro recommends not making transfers if possible, and says passengers headed to the Mall should consider using stations other than Smithsonian or Federal Triangle, which often see the heaviest ridership for events on the National Mall.
Metro says there's no scheduled track work planned for the holiday.
