I’ll reply to my own question in case someone else needs to know. This AM Beach Dr. was closed from Stony Brook to 355/Grosvenor, and looked like it was closed beyond 355 as well. The road is rideable, but has lots of small debris like leaves and twigs. Some areas have sand and mud. There’s a tree down and blocking the road just south of Connecticut, but you can ride under it if you duck.
Sligo Creek Parkway in Silver Spring was also closed, but there are no blockages.
