The traffic mess that started in the Georgetown area and then just got bigger and bigger during the evening rush is on its way to getting cleared up.

D.C. police said at about 6:40 p.m. Thursday that roads were being reopened and they were leaving the scene of the Swedish Embassy, after helping to sweep the building to make sure it was secure. Brian Leary, a spokesman for the Secret Service, said someone had called in a threat to the embassy at about 3:30.

After about three hours of sweeping the embassy in the 2900 block of K Street Northwest, D.C. police and members of the Secret Service didn’t find any suspect items or materials.

Traffic was said to be especially brutal in the West End, Georgetown and the Whitehurst Freeway, after authorities shutdown vehicle traffic in both directions in the area including Rock Creek Parkway near The Kennedy Center, K Street between 30th Street and Rock Creek Parkway, westbound 26th Street at Virginia Avenue, southbound 27th Street at K Street and the Potomac Parkway entrance to Rock Creek Parkway.
