(WAVY) — Virginia will be closing some interstates and bridges into Washington D.C. to increase security around the presidential inauguration.

The Virginia Department of Transportation and Virginia State Police announced the plans Friday night. The closures support ongoing security efforts under the United States Secret Service Joint Transportation Plan.

The closures will be from 6 a.m. Tuesday, Jan. 19 through 6 a.m., Thursday, Jan. 21 on the Interstate 66 and Interstate 395 bridges.

Officials in Virginia, D.C. and across the nation are all working to ensure security and safety across the country.

The FBI has warned of potential armed protests in all 50 state capitals, and U.S. Capitol officials have cracked down on security to ensure the Biden inauguration Jan. 20 goes smoothly.

Virginia Gov. Ralph Northam, U.S. Sens. Mark Warner and Tim Kaine, and U.S. Reps. Don Beyer, Gerry Connolly, and Jennifer Wexton — all Democrats from Virginia — issued a joint statement Friday about the closures ahead of the inauguration.

“The 2021 Presidential Inauguration Ceremony will see the strongest Capital-area security response in history. We worked together to push for a response that balances protecting public safety in a manner commensurate with available intelligence about threats without going too far. It is very important now that the U.S. Secret Service and its partner agencies communicate road and bridge closures swiftly and clearly in order to keep disruptions to a minimum. All of us want the transfer of power to be as peaceful as possible, and we thank all of the men and women in uniform helping to make this historic occasion safe.”
