Parking meters and most parking restrictions also will not be enforced, except along the H Street streetcar line and around Nationals Park.
Trash and recycling collection will be pushed to the following day, too.
Metro trains and buses will run on a normal weekday schedule.
The holiday, which commemorates the end of slavery in D.C., will include a fireworks display, parade and other events around the District.
On Capitol Hill, the Hill Center will celebrate the holiday with music and speakers honoring African Americans. More than a dozen poets and scholars will discuss black history and culture at the center from Thursday to Sunday as part of its Benjamin Drummond Emancipation Day Celebration. Drummond, a black Navy veteran, in 1866 was the first patient of the Civil War Naval Hospital, now the home of the Hill Center.
