 From Berwyn House toward Greenbelt Road, only single file getting by on Route 1. I-270, delay free from Rockville toward Frederick. Same goes on Route 50 between the Beltway and the Bay Bridge. Dinner at a diner? Yes, if it's Silver Diner. Silver Diner transforms everyday fare into elevated entrees. From fresh seafood and local steaks to vegan options, Silver Diner makes everyday meals extraordinary. Dave Dildine, WTOP Traffic.
