WASHINGTON (WNEW/AP) — For a third day in a row, demonstrators protesting a grand jury’s decision not to indict the white police officer who shot and killed an unarmed black teenager in Ferguson, Missouri blocked traffic in D.C., this time on the 14th Street Bridge.

Protesters lay in the roadway or stood holding hands and signs during the Monday morning commute. Police were at the scene and put up yellow tape to separate the protesters from stopped traffic.

The group shut down the road for about 40 minutes but then proceeded to move throughout the city. The protest has since broken up.

Another group later laid down in front of the Justice Department headquarters in D.C. The protest was expected to continue with a rally later Monday afternoon at the Justice Department.

On Sunday, demonstrators blocked the Southeast-Southwest Freeway of Interstate-395.

The D.C. Department of Transportation reported the highway was closed Sunday afternoon near the 3rd Street Tunnel. Images online showed a line of protesters holding hands, blocking traffic in both directions. Police were on the scene.

The highway was reopened to traffic a short time later.

Some people alongside the protest were holding signs opposing the Ferguson, Missouri, grand jury decision from last week.

On Saturday, protesters blocked streets in the busy Georgetown neighborhood and in the Pentagon City area of Arlington County. The protests remained peaceful and nonviolent.
