— Duke Energy crews were investigating a charred transmission box as the source of a power outage Tuesday that left more than 8,000 customers in the dark and tied up traffic in north Raleigh.

Crews found a burned out box on StoneCliff Drive.

According to Duke, transmission lines were damaged just before noon, knocking the power out and traffic signals offline in an area extending north and west from the Beltline along Glenwood Avenue and Creedmoor Road from just before noon.

Most customers were back online by 2 p.m.
