Concrete jersey barriers block many of the cross streets along K Street NW, police officers are screening people coming into downtown, and Metro has closed some of its busiest transfer stations within the security perimeter this weekend.

More fencing is going up in a farther perimeter around the Capitol and White House. The National Mall and other National Park Service areas nearby are closed.

Mayor Muriel Bowser is urging people not to come to the Downtown Central Business District area, which roughly stretches from east of the Capitol to the Lincoln Memorial and north to Massachusetts Avenue. She also told would-be visitors to stay out of Washington.

Many parking garages near the Capitol and White House were shuttered Friday. Vehicles left inside won’t be accessible until after the inauguration, officials said. Trucks delivering to businesses in the area will be sent to an off-site inspection point first.

These are just some of the unprecedented security measures taking place ahead of President-elect Joe Biden’s inauguration Wednesday. It’s set to take place just two weeks after a violent attack on the U.S. Capitol by supporters of President Donald Trump. The FBI is tracking threats of violence at the U.S. Capitol and at state capitals around the country in the coming days.
