All lanes of the outer loop of the Beltway before Georgia Avenue were closed following an accident Thursday morning.

The accident happened in the left lane about 6 a.m. Police temporarily brought traffic to a standstill while they moved the vehicles involved in the collision to the right side of the roadway.

An estimate of when the lanes would be reopened was not immediately available, but officials said the closure was temporary. Delays are expected to continue even after some lanes are reopened.
