6:45 A.M. Update:

Justin Jouvenal has more details on the shooting that has shut down northbound Baltimore-Washington Parkway this morning. But if your commute normally involves taking that roadway, we’d advise heading a different way. It should be closed for a few hours. Heading over to the Beltway and I-95 North might be your best bet.

6:25 A.M. Update:

Northbound I-95 is very, very congested leading up to the Springfield Interchange. Delays essentially run from Woodbridge to the interchange.
