 There is an incident still bottlenecking traffic and backing up inbound drivers on Route 50 in Chevrolet. Parkway southbound after 197 had one stopped along the left. Northbound traffic still heavy in Greenbelt. 270 is pretty much cleared out. Rockville to Frederick. Our traffic center is presented by Window Nation. Get 50% off all styles of windows. It's at windownation.com. I'm Dave Daldine, WTOP Traffic.
