DelDOT Puts Up Another HAR?

I've noticed that the WTMC network of HAR stations, run by the Delaware Department of Transportation on 1380 may have put up a new transmitter. I was getting overloading of the WTMC signal in north Dover, near exit 104 off Route 1, at the intersection of US13 and Scarborough Road. Sure enough, a new HAR transmitter tower is there, similar to the new one in Smyrna, at exit 114 off Route 1. I don't know if this replaces the transmitter that is already on the air in south Dover near the Puncheon Run Connector or if this is an additional transmitter, which would bring to 5 stations on 1380, run by DelDOT- the main station in Wilmington, Smyrna, two now in Dover and in Rehoboth Beach.
