 Traffic and weather on the 8s. Here's Bob Imler in the WTOP Traffic Center. In northwest D.C., a stretch of Shoreham Drive and also Cathedral Avenue closed because of police activity. So that if you're northbound on Rock Creek Parkway, you must continue up Beach Drive. You will not be able to go up either Cathedral or Shoreham Drive up toward Connecticut and Calvert. That is all closed right now because of this police activity, but you can go up to Porter Street on Beach Drive.
