 The delay on the Baltimore-Washington Parkway begins inside the Beltway. This is northbound from 410 solid into Greenbelt. It is near Nassau Goddard. The left lane gets by the work, seeing an unusual delay on 95 northbound coming from the outer loop of the Beltway, headed to the point where both loops of the Beltway merge together on northbound 95 before 212. Southbound has a bit of a delay as well, so watch for any activity. Not sure which direction it's in, but there may be something causing the slowdown.
