Museum groundbreaking to snarl traffic around Mall

8:40 A.M. Update:

President Obama, Michelle Obama and former first lady Laura Bush are expected to speak at the groundbreaking for the National Museum of African American History and Culture later this morning. The ceremony will be held at 10 a.m. inside a tent on the museum’s future site at 14th Street and Constitution Avenue NW.

This event isn’t open to the public (it will be streamed live here), but it will still impact traffic in the surrounding area. The following roads are either already closed or will be closed due to the ceremony, according to the Smithsonian:

• 15th Street between Independence Avenue and Constitution Avenue (closed 6 a.m. until noon)

• Madison Drive and Jefferson Drive between 14th Street and 15th Street (closed 6 a.m. until noon)

• Constitution Avenue between 12th Street and 17th Street (closed 9:45 a.m. until noon)

Additionally, parking has been prohibited on Madison Drive between 12th and 14th street since 12:01 a.m.

7:45 A.M. Update:

An accident on northbound Falls Road/MD 189 at I-270 could cause delays there.

A disabled vehicle on the I-95 reversible lanes before Occoquan could also cause issues around that area, but it’s unknown right now if any lanes are blocked.

7:25 A.M. Update:

The dedication of the National Museum of African American History and Culture later this morning will slow traffic due to the presidential motorcade. There are already some road closures caused by this event:

• 15th Street between Independence Avenue and Constitution Avenue (closed 6 a.m. until noon)

• Madison Drive and Jefferson Drive between 14th Street and 15th Street (closed 6 a.m. until noon)

• Madison Drive between 12th Street and 14th Street (closed 8 a.m. until noon)

• The 12th Street ramp from Constitution Avenue to Madison Drive (closed 8 a.m. until noon)

• 14th Street between Independence Avenue and Constitution Avenue (closed 9:45 a.m. until noon)

• Constitution Avenue between 12th Street and 17th Street (closed 9:45 a.m. until noon)

Additionally, parking has been prohibited on Madison Drive between 12th and 14th street since 12:01 a.m.

7:20 A.M. Update:

The accident on I-270 South at the 270 Spur has been cleared and all lanes reopened.

7:05 A.M. Update:

An accident on I-270 South at the 270 Spur is blocking two southbound lanes and one of the southbound shoulders.

President Obama, Michelle Obama and former first lady Laura Bush are expected to speak at the dedication for the National Museum of African American History and Culture later this morning. The ceremony will be held at 10 a.m. inside a tent on the museum’s future site at 14th Street and Constitution Avenue NW.

This event isn’t open to the public (it will be streamed live here), but you should still expect it to impact traffic in the surrounding area. And while this venue is right near the White House, you should definitely expect the usual congestion that occurs when the president has to drive somewhere.

6:45 A.M. Update:

A disabled vehicle on I-95 South in Baltimore’s Fort McHenry Tunnel is blocking one southbound lane.

A disabled vehicle on I-95 North after Lorton is blocking the right shoulder.

6:30 A.M. Update:

The delays on I-66 East have gotten worse leading up to Chain Bridge Road.

Additionally, the inner loop of the Beltway is slow before Gallows Road.

6:15 A.M. Update:

The accident on I-66 East at Chain Bridge Road has been cleared and the left lane and left shoulder have reopened. I-66 East is heavily backed up approaching this spot.

The disabled vehicle on I-95 North at Joplin Road in Triangle has been cleared from the right lane and right shoulder.
