Trooper Mark Samosky said a woman was using her GPS to get back on the highway after filling up at a gas station on Truck Stop Road.
Samosky said the driver turned right on the service road rather than taking the entrance ramp for I-95 South.
He said she then looked down at her GPS and drove off of the road.
She then hit a guy wire that supports the power pole, bringing down the power lines and covering all four lanes of the roadway.
The roadway was reopened by 6:30 a.m.
