 Baltimore-Washington Parkway slowing northbound through Greenbelt on your way toward Laurel. Southbound jammed as usual, leaving Jessup toward 32 in the NSA. On 270 northbound after 118, the crash apparently at last report you were getting by staying to the left with a brief slowdown there. Farther north, you'll slow again through Clarksburg and a volume delay toward the lane drop.
