A road sign on I-95 in Delaware County had a message for Delaware County - and its drivers - and it was not a pretty one. Someone hacked into the electronic sign on I-95 near the Ridley Park exit twice and turned it into a vulgar message. The electronic board was commandeered to offer a three-word screed: Announcing “Delco, followed by an expletive and lastly an anatomical reference,” along with what appeared to be several initials. The message on the board displayed the nasty announcement most of the day. After it was corrected once, it was changed again. Eventually the sign was shifted so that it did not face the highway. The message was first noticed about 9 a.m. Sunday. PennDOT said they dispatched a crew to reset the sign about 10 a.m., but it was changed again later in the day. After being reset however, the sign was once again hacked with the same message. A crew then returned to the sign and powered it off. PennDOT said the board, which is used to note road projects, belongs to one of its contractors. PennDOT officials said they now are investigating to see how the board was changed and who might be responsible. They also will look into security measures to make sure it does not happen again.
