Astor - East Broad Street 138-kV Transmission Line Rebuild Project
AEP Ohio representatives plan power grid upgrades in eastern Columbus. The project involves rebuilding just under 3 miles of 138-kilovolt (kV) transmission line connecting AEP Ohio's Astor Substation off Astor Avenue to the East Broad Street Substation off East Broad Street near McNaughten Road.
The poles and wires along the nearly 70-year-old transmission line have deteriorated and require frequent maintenance. Company representatives need to replace the line as it approaches the end of its useful service life. Installing modern steel poles and wires reduces power outages and improves the local electric service reliability.
* This project requires Ohio Power Siting Board (OPSB) approval.
Project Updates
Summer 2026: Pre-construction activities are ongoing along McNaughten Road as crews begin site preparation ahead of construction. Motorists along McNaughten Road should expect temporary lane closures with flaggers on-site as needed to maintain safe traffic flow. These lane closures will be temporary and move as the work progresses. Crews expect to begin construction in September and conclude by early 2027.
