An accident during road construction efforts in Westmoreland County is to blame for WKHB-AM (620) and WKFB-AM (770) being knocked off the air on Thursday. Crews working near the transmitter site apparently damaged a few phone poles worth of the phone lines used to carry the station signals to the transmitter. Lines above and below ground were damaged. Crews hope to have service restored sometime today.

In related news, new FM sister station, WKVE (103.1) Mt. Pleasant, is in its third full day of broadcasting from Chestnut Ridge using a line-of-sight studio to transmitter relay.

UPDATE: WKHB and WKFB returned to the air shortly after this story ran.
