District government offices and schools are closed Friday in observance of Emancipation Day.
That means weekend or holiday traffic patterns in the city will be in effect.
There will also be no parking enforcement. That includes tickets for expired meters, residential parking and rush-hour violations. Trash and recycling collection scheduled for Friday will move to Saturday.
Emancipation Day is April 16, but the District is observing it on Friday.
Emancipation Day marks the occasion on April 16, 1862, when President Abraham Lincoln signed an act freeing slaves in D.C. Some 3,100 slaves were freed by the act. Lincoln freed the slaves in D.C. nine months before he issued the Emancipation Proclamation, which led to all slaves being freed.
