WMATA sent out an alert just before 8:30 a.m. that a suspicious package investigation at Farragut West had closed the 18th & I Street station entrance, and we’ve since heard that the surface streets surrounding the area were also closed, leading to an impressively bad traffic jam. Metro gave the all-clear at 9:23 a.m., but not before many a commuter was stuck in a mess at the height of the morning rush. The area should be getting back to normal by now. UPDATE: The Post is now reporting that the suspicious package in question turned out to be an empty can inside a garbage bin. But what kind of a can? A soda can? A can of beans? Coffee can? CAN-bus?
