Tuesday is Emancipation Day, a holiday in the District celebrating the 1862 date on which President Abraham Lincoln freed slaves in the nation’s capital. Since it’s not a holiday for federal workers or most private employees, all the normal rush hour traffic and parking restrictions will be in effect.

However, other parking regulations, including expired meters, residential parking and street sweeping rules, will be suspended for the holiday. The Department of Motor Vehicles will be closed.

A holiday parade and festival is scheduled to start at 11 a.m. at Fourth Street and Pennsylvania Avenue NW and end at Freedom Plaza along 14th Street NW.

These streets are closed until 11 p.m.: E Street NW from 14th to 13th streets, Pennsylvania Avenue NW from 14th to 12th streets,13th Street NW from E Street to Pennsylvania Avenue.

These streets will be closed from 9 a.m. to 2 p.m.: Constitution Avenue NW from Ninth Street to Pennsylvania Avenue, Seventh Street from Pennsylvania Avenue to Independence Avenue SW.

These streets will be closed from 10 a.m. to 2 p.m.: Pennsylvania Avenue from 12th Street to Third Street NW, all streets crossing Pennsylvania Avenue from 12th to Fourth street between E Street and Constitution Avenue.

Police may decide to temporarily close other streets as well. Travelers and parade-goers are likely to see more police Tuesday as various agencies take security precautions in the wake of Monday’s bombing at the Boston Marathon.
