 WBAL News Radio 1090 and FM 101.5. Traffic and weather. Good afternoon. Something's going on on the Harrisburg Expressway northbound just past the Maryland-Pennsylvania line causing significant delays for those of you heading to PA via 83. Thanks for our listener who called in on our traffic tip line to tell us about that incident. In Howard County, northbound Maryland 100 very heavy and slow approaching the 29 merge as folks head to Ellicott City from Columbia.
