 WBAL News Radio 1090 and FM 101.5. Traffic. The accident on the northbound side of the BW Parkway after 197, that has been cleared, but now we have a new one. This is going to be on the northbound side of the BW Parkway before you get to Powder Mill Road, but north of NASA Goddard. So just be ready for delays going northbound of the BW Parkway through Greenbelt.
