 starting at about 410 all the way beyond the Beltway. That's because of some road work being done that is taking away the right lane between Greenbelt Road and Beaver Dam Road. Once you get past that work zone, northbound should be clear moving up towards Baltimore, but southbound of the BW Parkway, slow between Arundel Mills Boulevard and a little bit past 32. In between there somewhere, there is some reported crash activity, unsure of which side of the road may be affected.
