(Updated at 11:00 a.m.) Traffic backups caused by a barricade situation in downtown D.C. have spilled over into Arlington.
In Rosslyn, traffic on Lynn Street approaching the Key Bridge is backed up all the way to the Iwo Jima memorial.
The Memorial Bridge, Route 50, I-66 and I-395 are all slow and congested approaching the city, even at 10 a.m. Heavy traffic has also been reported on large portions of the GW Parkway and Washington Blvd near the Pentagon.
Reports out of D.C. suggest a mentally unstable person, possibly armed with a high-powered rifle, is barricaded in a downtown office building. Police have closed a multiple block portion of downtown near the Farragut North Metro station to pedestrians and vehicles.
As of 11 a.m., the suspect was reported to be in custody.
