Update: Two lanes reopen on outer loop from 50 to 202

UPDATE (2:48 p.m.): All lanes have reopened on the Outer Loop, according to Lora Rakowski from the Maryland State Highway Administration. The road is clearing up, but motorists should still expect slight delays from residual backups.

UPDATE (2:10 p.m.): Two left lanes of the Outer Loop, between US 50 and Route 202, have reopened after being closed for nearly three hours. Lora Rakowski from the Maryland State Highway Administration said that two right lanes remain closed as crews conduct their investigation. A detour was lifted, but traffic stretches back to about MD-214, approximately five miles. Expect delays if traveling through the area. Rakowski could not estimate when all lanes will return to service.

ORIGINAL POST (12:38 p.m): All lanes on the Outer Loop of the Beltway between US 50 and Route 202 are closed while police investigate a multi-vehicle collision that ended a police chase about 11:20 a.m., authorities said.

Trooper Jeff Deibel, of the Maryland State Police College Park barracks, said that there was a police pursuit of a vehicle that ended at the scene.
"There's an investigation into the pursuit," he said. "I can't comment on injuries."

Lora Rakowski from the Maryland State Highway Administration said that the crash happened just before US 50.

The road is closed at MD-202. All the vehicles that were on the road between those two points are being turned around, she said. A detour is being set up at 12:30 p.m., and traffic operations officials have arrived at the scene. Exact details of the detour weren't yet available.

The 202 ramp to the Outer Loop is also closed. No lanes are closed on the Inner Loop in that area, but Rakowski said traffic is moving slowly and drivers should expect delays.

She said she could not offer a guess at when the road will reopen.
