Traffic is backed up in both directions on U.S. Highway 98 near its intersection with North Holiday Road in South Walton.
A dump truck hit a power pole around 8 a.m., according to Corey Dobridnia, spokeswoman for the Walton County Sheriff's Office. The collision left a live power line across all four lanes of the highway.
Dobridnia said traffic was backed up westbound to Silver Sands Premium Outlets and eastbound for three or four miles.
All four lanes were closed while power crews worked to deactivate the lines. As of 11:30 a.m. the highway was reopened according to Dobridnia.
