I-75 Transmission Line Relocation Study

Transmission Investments

Duke Energy's electric system is essential to meeting our customers' needs. We're also committed to the development, stability and economic growth of the communities we serve. With that in mind, Duke Energy Ohio will be relocating a short section of a 69-kilovolt (kV) electric line to accommodate an Ohio Department of Transportation (ODOT) project.

Project Need

ODOT is planning future work to improve safety and ease congestion on I-75 in Hamilton County, which involves reconstructing I-75 between the bridge over the Mill Creek and the Ronald Reagan Cross County Highway – adding a fourth lane in either direction.
ODOT's I-75 project requires Duke Energy to relocate our poles, towers, electric power line and other associated equipment to new road right of way and into a new transmission corridor.

Project Description

Duke Energy Ohio will need to relocate about a half-mile of 69-kilovolt (kV) electric transmission line and related equipment from crossing I-75 near the 10.10 mile marker. Construction on the transmission line portion of the project is planned to begin in fall 2021.


Community engagement is a vital part of our siting process. It allows us to receive and consider public input and to share information with the community about this project. We invited landowners within 500 feet of the study area to send us their feedback. The public comment period was held from Jan. 4 to Feb. 3, 2021

After examining public comment and additional study on how to best approach the project with the least impact to property owners, the community and the environment, we shared our findings for the preferred route, Segments 2 and 5, which are detailed on the map. Landowners in the study area received the announcement on June 14, 2021.

We believe this option will have the least overall impact on property owners, businesses, historic areas and the environment. The precise location of the transmission line and pole structures within the easement will be determined following a detailed route survey, additional field study and completion of the engineering design of the route.
