 WDEL, Delaware's news radio from the Highmark Blue Cross Blue Shield sponsored studio. Highmark, the plan Delawareans have counted on for more than 80 years. 519 now on WDEL to the roads for Traffic Watch. Here's Mike Phillips. Thank you very much, Chris. When we started this afternoon, I-95 Northbound was backed up from the service area, the Welcome Center, right up into Churchman's Marsh. Not that way anymore. It's really improved over the past 90 minutes or so. 95 Northbound is still very busy.
