Metropolitan Police Department officers spread traffic barriers along the length of 20th Street on campus Tuesday as part of the department’s security provisions for the upcoming presidential inauguration.

Officers installed the security fencing barriers along 3rd and 20th streets NW between L Street and Independence Avenue at 7:40 p.m. Tuesday, according to an MPD traffic advisory. The advisory states the closures are “subject to change” and instructs commuters to look out for directions from MPD officers and U.S. Park Police.

MPD spokesperson Hugh Carew declined a request for comment.

MPD issued a previous traffic advisory Monday night via Twitter, notifying locals about parking restrictions and street closures that would go into effect at 6 a.m. Tuesday.

“Morning commuters should be aware of parking restrictions and potential street closures in the downtown area,” the advisory reads. “Stay tuned for additional updates.”
