Authorities have closed off 15th Street between L and M Streets this afternoon after a suspicious package was found in an underground parking garage, according to the Washington Post. Workers have been evacuated from the building above the garage. More details when we get them. The 15th Street package — and a very brief package concern at the L Street entrance to Farragut North — have both been cleared as non-hazardous. (Also, we want to assure everyone that J Street NW is completely back to normal.)
