Drivers in the District of Columbia, take note: the 30th Annual Blue Mass is coming to town, and with it, a slew of street closures and parking restrictions on Tuesday, May 7. The event, which honors law enforcement officers and first responders, will be triggering shutdowns on selected streets from 6:00 a.m. to 2:00 p.m.

According to an advisory released by the Metropolitan Police Department, the affected areas include 10th Street between F Street and H Street, NW; G Street between 9th Street and 11th Street, NW; and, G Place between 9th Street and 10th Street, NW. That means no parking and a full stop on vehicle traffic. These temporary traffic measures are critical for the smooth operation of the Blue Mass, a tradition stretching back decades in the heart of the capital. Now entering its 30th iteration, the event draws attendees from myriad law enforcement agencies as well as fire and rescue departments.

For those affected by the street closures, alternative routes should be considered. The police department has urged folks to stay informed about the traffic situation by keeping an eye on local news and the official Metropolitan Police Department's traffic advisory page.
